What do I think about the stability of the solution?

The system has maintained a high level of stability, although managing licenses and testing can be a bit challenging, especially for large organizations like ours. The downtime occurrences have been relatively rare, with any issues that arise being promptly and effectively resolved.

What do I think about the scalability of the solution?

It's highly scalable and you can easily expand your licenses and integrate new capabilities and modules. We can also tap into other solutions by simply using plug-ins, which provide the capabilities we need, and scalability remains a straightforward process.

How are customer service and support?

We occasionally rely on tech support, and while they often meet our expectations, there are instances where our anticipated resolution timelines are not met. This can be attributed to the prolonged engagement period. On a positive note, the overall experience with support has been satisfactory, with most interactions going smoothly. I would rate it eight out of ten.

How was the initial setup?

The initial setup is quite straightforward and not overly complex

What about the implementation team?

The deployment process doesn't differ significantly from other solutions. It involves integrating with our online domain controllers for authentication and setting up the system. It's a straightforward process without complex steps or unique challenges, we collaborate directly with the OEM, without involving external consultants.

What's my experience with pricing, setup cost, and licensing?

I find it reasonably priced.

What other advice do I have?

Overall, I would rate it eight out of ten.

Disclosure: My company does not have a business relationship with this vendor other than being a customer.

An easy, simple, and secure product with an excellent message-tracing feature
Pros and Cons
  • "Message trace is the most valuable feature of the product."
  • "The interface is a bit confusing."

What is our primary use case?

The product is used to create email addresses. We can also create groups and distribution lists. The product also provides email forwarding features. We can create rules, monitor the flow of emails, and trace messages. We can use connectors on the platform for email security and email signature.

What is most valuable?

Message trace is the most valuable feature of the product. We can get a customized report on what is happening in our environment. We can trace all the emails, understand what happened, and get information on how they reached the user and the hops before delivery. It is very interesting.

We can also know how many deliveries failed and are pending in the queue and customize our reports how we want them to be. The product is very easy, simple, and secure. It is available everywhere because it is cloud-based.

What needs improvement?

The solution should have a better interface. The interface is a bit confusing. It should be more simple. The product should also improve the email flow. The rules are a bit complicated compared to the previous version. The previous version was much easier, and the latest one is more complicated.

For how long have I used the solution?

I have been using the solution for four to five years.

What do I think about the scalability of the solution?

In my organization, 150 people use the product. I have plans to increase the usage by 10% in one or two years, depending on how much the organization will grow. The product is extensively used in our company.

How are customer service and support?

I had a very good first impression of the technical support team. Technically, the team is very good, very supportive, and very friendly. The team members are well-mannered while talking to customers. They follow up very well and are with us until the case is closed and we are satisfied.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

I was using Lotus Notes five to six years ago. It was centrally based in our head office. I didn’t contribute to it. Later, when I applied to have my own email solution, I chose Microsoft.

How was the initial setup?

The solution is very easy to set up. We just have to enter the username and password and start using it. We can deploy emails to end users within five to ten minutes. The product is cloud-based.

What was our ROI?

In our business, everything is done by email applications, Microsoft Excel, and Microsoft Word. So, we get a 60% ROI on the solution.

What's my experience with pricing, setup cost, and licensing?

We pay a yearly licensing fee for the solution. The cost depends upon the plans we choose and the types of applications we want to use. We have a three-year deal with Microsoft to get a good price for the product. They are very willing to revise the price, accompany us for the setup, and give us a framework. They are very impressive to work with. There are no additional costs associated with the product.

What other advice do I have?

I am using the latest version of the solution. Most businesses and users are using Microsoft for email business. I would recommend the solution to others. Overall, I rate the solution a ten out of ten.

Quick to deploy, easy to set up, and works with minimal issue
Pros and Cons
  • "It does what it's supposed to do with minimal issues, and the solution is very easy to set up and quite quick to deploy."
  • "When you migrate from on-prem to cloud, if you choose to or are forced to do the hybrid, they need to devise a way to undo the hybrid."

What is our primary use case?

We primarily use the solution for email and calendar functionality.

What is most valuable?

It works. It does what it's supposed to do with minimal issues.

It's one of the products that Microsoft has absolutely done its very best with.

The solution is very easy to set up and quite quick to deploy.

What needs improvement?

Right off the top of my head, I can't think of anything that I would change to improve Exchange.

The pricing could always be better.

Right now, I'm writing documentation to upgrade the existing Exchange and Active Directory from 2016 to 2019.

When you migrate from on-prem to cloud, if you choose to or are forced to do the hybrid, they need to devise a way to undo the hybrid. At present, once you establish a hybrid organization between cloud and on-prem, there's no way to undo it. Fixing that would be most beneficial. At the last organization I was at and did a migration, I had 31,000 users, and my largest mailbox was 90 gigs. It took three months to complete the migration.

We had no choice but to put it into hybrid mode due to the period of time. The MX record can only exist in one place. Therefore, you can't route mail from one system to another system. All the mail had to be routed through the on-prem and then synced from the on-prem to the cloud until everything was in the cloud. Then we were able to move the MX record from being on-prem to being in the cloud. Then all mail could be received in the cloud. However, then there was no way to tear down the Exchange organization on-prem. We are still left with a server, server maintenance, licensing, OS upgrades, patching, and everything on the on-prem server. The on-prem server is literally sitting there doing nothing except filtering air in the data center, costing me power, time and cooling. Therefore, fixing that would be awesome.

For how long have I used the solution?

I’ve used the solution throughout my career - for over 30 years.

How are customer service and support?

Typically, by the time I open a ticket, and they get back to me, I've figured out how to fix it. I don't call them until I'm really stuck.

They're not very good. I have had one of their technicians call me back more than once, and I'll go, "I figured it out, I fixed it." They flat asked me, "Well, how did you fix it?" I'm like, "You're Microsoft. You figure it out." They may not have the best understanding of the system.

How would you rate customer service and support?

Neutral

Which solution did I use previously and why did I switch?

I've used Exchange my entire career. My best friend is currently trying to get rid of Lotus Notes where he's at. He's been working on that for a year now, and it just doesn't seem to want to go away. I've always been with this product. I did a bunch of work with GroupWise and got GroupWise out of the environment and so forth - replacing that with Active Directory. However, that really didn't have a mail component to it.

How was the initial setup?

The initial setup is very straightforward. It only took a few hours to deploy.

What's my experience with pricing, setup cost, and licensing?

The pricing is always something that could be better. We always like to work towards protecting our budget.

I know what the cloud cost per user is. I don't have what the on-premises costs are.

What other advice do I have?

I’m a customer. I don't have any direct relationship with Microsoft.

I’d rate the solution a nine out of ten.

It's an excellent product. It's an excellent mail system. It does exactly what it's supposed to do. If you are under 5,000 employees, I would say that Microsoft 365 is the way to go. If you're over 3,000 or 5,000 employees, I would have some serious conversations about on-prem versus cloud. Once you get over about 3,000 or 5,000 employees that are mail users, the cloud really starts to get much more expensive than on-prem.

A stable and user-friendly solution that provides various productivity tools and enables communication
Pros and Cons
  • "The product enables us to have remote meetings."
  • "The solution must provide better security features."

What is our primary use case?

I manage the tool. All of our business activities happen with the help of the tool. We also have SharePoint integrated into it. We have several other packages listed on the Exchange platform.

What is most valuable?

The product enables us to have remote meetings. Several valuable resources like SharePoint are available to us. It has been our basic tool for communication in an enterprise environment. It's user-friendly. The interfaces are quite friendly. We can navigate around interfaces and tasks. It has several productivity tools attached to it. I can have it deployed on the local computer and the cloud. As long as we have access to the internet, the tool is accessible anywhere in the world. It is a seamless and excellent product. It is a critical support platform.

What needs improvement?

The solution must provide better security features. It provides two-factor authentication, IPSec, security payload, and other authentication and encapsulation. I want more consignment of the access to identify users.

For how long have I used the solution?

I have been using the solution for about 15 years.

What do I think about the stability of the solution?

The tool’s stability is excellent. The server hardly goes down. In ten years, I hardly recall any downtime.

What do I think about the scalability of the solution?

We have more than 300 to 400 users.

How are customer service and support?

The support is excellent.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

We chose the solution because our sister companies and other associates were using it.

How was the initial setup?

The setup was not difficult. We created a domain and implemented it with the help of a third-party company that is a partner with Microsoft. I do the annual renewal of our licensees. We have moved from enterprise licenses to educational licenses. Educational licenses have certain benefits and discounts.

What's my experience with pricing, setup cost, and licensing?

The product is very cheap. It is relatively affordable.

What other advice do I have?

If someone plans to use the solution, they must consider the number of users. They must choose the license model depending on their organization. The documentation must be put together in detail, and the right model must be chosen. Overall, I rate the tool a ten out of ten.

Which deployment model are you using for this solution?

Public Cloud

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

The tool has diverse functions and excellent support
Pros and Cons
  • "Microsoft has many consultants who can provide support."
  • "It is tricky to integrate Microsoft Exchange Online if you are in an infrastructure provided by other vendors."

What is our primary use case?

I work for civil ministries, and we exclusively use Microsoft products because we get them for a low price.

I handle security with Fortinet, and I run virtualization with Citrix. Those are my main tasks.

What is most valuable?

Microsoft has many consultants who can provide support.

What needs improvement?

Some of the Microsoft implementations of protocols are far from standard. They make their own standards, and you're out if you can't convert to them. With other Unix-based solutions, we had more flexibility to react to special problems we needed to solve. We can only solve the problem now if the problem is solvable with Microsoft.

Similarly, it is tricky to integrate Microsoft Exchange Online if you are in an infrastructure provided by other vendors. We have had an alternative solution to Exchange since 2016, and if we had problems, it was never a problem with Microsoft. It was a problem with the alternative product. The problem is that Microsoft has a standard, and you need to stick to it.

Even if the reason for the problems is Microsoft, the SMTP stack in Exchange is far from the RC of SMTP. If the alternative solution makes extensions to DNS for their active directory and if you use an RC DNS server, you would have problems with some of the records that Microsoft produces. They are not replicated. If you begin with Microsoft, you make everything Microsoft. It is difficult to mix Microsoft with other vendors or with other products. And you get less support if you want to choose a solution other than Microsoft.

Moreover, Exchange Online should work on integration with other services like Teams because when they work together, you gain benefits that other companies might not be able to give you.

For how long have I used the solution?

I have been using Microsoft Exchange Online since 2012, and we will use it in the future.

Which solution did I use previously and why did I switch?

We formerly worked with Unix-based mail servers. The positive side is that you're flexible. You could use different hardware. You get limited with Microsoft.

What's my experience with pricing, setup cost, and licensing?

Microsoft solutions are expensive.

What other advice do I have?

I prefer to use solutions like LibreOffice since they are free and cheaper, but our partners might have problems reading our data, and we would face difficulties cooperating.

The main problem with Microsoft products is that we get very dependent on them. Until 2016, I had to make decisions for the budget for the Southwest of Germany, and when you work with Microsoft, your budget is fixed to them, and you lose your ability to work with other solutions. That was a bad situation for us.

If you don't plan to use other solutions in the future, it's a good product. Otherwise, you have to be prepared that some problems may arise. Once you get married to Microsoft, it's a fierce divorce if you want to leave. I rate the solution an eight to nine out of ten.

Secure with good support and an easy implementation
Pros and Cons
  • "It's not hard to set up."
  • "We'd like to see more integration with other platforms."

What is our primary use case?

We are primarily using the solution for Office 365 and various other Microsoft products. It's used for any integration of any applications. Multiple company domains have been configured on a single exchange. It helps us standardize and consolidate connectivity. 

What is most valuable?

We like the standardization we can get across all of our companies. We can put all domains on one exchange. The user can then have one single ID instead of creating five emails for one user. 

It scales well.

Technical support is helpful.

It's not hard to set up.

The solution is stable.

The product offers good value for money. After a few years, we have seen an ROI. 

What needs improvement?

There are no features that are missing.

We'd like to see more integration with other platforms. We'd like to explore the feature of SSO and Artemis. 

For how long have I used the solution?

I've used the solution for more than three years. 

What do I think about the stability of the solution?

The solution is stable and reliable. There are no bugs or glitches. It's very stable. 

What do I think about the scalability of the solution?

The solution can scale well. It's cloud-based, which makes it very simple. We just have to approach our reseller and add on more licenses. You can have 50 users or 50,000 users, and it will work just as well. 

We have about 1,000 or more users on the product currently. We do have plans to increase it to 1,500 by the end of the year. 

How are customer service and support?

We may have used technical support previously and were able to resolve any issues within a week. They are very good. They are helpful.

Which solution did I use previously and why did I switch?

I did not previously use a different solution. Past colleagues may have used something else. 

How was the initial setup?

The initial setup takes two to four weeks. It's pretty straightforward. We take each domain and consolidate everything on the exchange. We can migrate everything in one go, and usually, we migrate each company each week and migrate one by one, so that end users are not disturbed. 

What was our ROI?

We have experienced an ROI after three to four years. 

What's my experience with pricing, setup cost, and licensing?

We pay for the solution annually. The price is a bit expensive. However, it offers good value for money. The implementation cost is minimal. Also, now it is on the cloud, we don't have to worry about storage, maintenance, or hardware. The cloud is highly secure, and it helps save us money in the long run. 

What other advice do I have?

This is the latest version. We are using the cloud version, and it is constantly updated. We are using all of the standard features that come with the cloud-based product. 

This is a very user-friendly enterprise solution. Everything is very secure according to GDPR needs. The product is scalable, and its offering good value for money. Everyone can use it. It's a great product.

I'd rate the solution nine out of ten.

Quite convenient access from anywhere but the UI could be improved
Pros and Cons
  • "The solution is quite convenient because you can access the web version anywhere."
  • "The UI could be improved to look more like the desktop version for ease of use."

What is our primary use case?

Our company used the solution as an alternative to desktops for accessing emails remotely. It is a front-end email application that can be accessed from the web.

The solution allowed us to create new emails, collaborate via online surveys, and get feedback from a group of engineers on a specific items. We had 2,000 users across our company. 

The solution more or less is an online collaboration tool.  

What is most valuable?

The solution is quite convenient because you can access the web version anywhere. You aren't tied to a company-provided laptop where you have your Outlook desktop.  

What needs improvement?

The UI could be improved to look more like the desktop version for ease of use. 

For how long have I used the solution?

I used the solution all the time as an end user with my prior employer. 

What do I think about the stability of the solution?

The solution is stable with no issues. 

What do I think about the scalability of the solution?

The solution is scalable because it is on the Microsoft cloud. The sky is the limit. 

How are customer service and support?

As an end user, I contacted our internal support team. They actually handled reaching out to Microsoft's technical support. The process didn't take a lot of time and was quite transparent. We received feedback within 24 hours. 

How was the initial setup?

The solution is cloud-based and accessed via a website so there is no setup. You just point to the URL, provide any extensions, and log in to the solution. 

What about the implementation team?

We implemented the solution in-house. 

Our IT department deployed by installing exchange server and enabling a shared configuration item. This allowed all users to access the solution via the web. 

Deployment shouldn't take more than two hours because you just enable the web for the online exchange. Then you share a link or the URL so users can access the solution. 

What was our ROI?

Our company achieved ROI by using the solution. 

What's my experience with pricing, setup cost, and licensing?

The pricing is based on a yearly contract and a floating license option is offered.

What other advice do I have?

I strongly recommend using the solution. 

Which deployment model are you using for this solution?

Easy to use, and straightforward deployment, but is not stable
Pros and Cons
  • "The solution is scalable."
  • "The stability of the solution has room for improvement."

What is our primary use case?

The primary use case of the solution is for email and SharePoint.

How has it helped my organization?

We are beginning to explore Office 365 Online Exchange and Azure, which are part of Microsoft 365. We intend to create our Active Directory and Domain Controller on Azure and integrate OnTime Active Directory with Azure Active Directory.

What is most valuable?

I haven't encountered any downtime with Exchange Online so far. Last week, the entire Azure portal experienced an outage, which caused some disruption, but thankfully, we haven't had any issues with 365 yet.

What needs improvement?

The stability of the solution has room for improvement.

For how long have I used the solution?

I have been using the solution for over four years.

What do I think about the stability of the solution?

I give the stability a seven out of ten.

What do I think about the scalability of the solution?

The solution is scalable.

We have thousands of people using Microsoft Exchange Online.

How are customer service and support?

We have a limited amount of time to contact tech support, but we usually communicate with the vendor. If I have an issue, our Microsoft partner can help us with problem-solving.

Which solution did I use previously and why did I switch?

We previously used Google G Suite before switching to Microsoft Exchange Online.

How was the initial setup?

The initial setup is straightforward.

What about the implementation team?

The implementation was completed in-house with the help of our Microsoft partner.

What was our ROI?

We have seen a return on investment since we are taking advantage of the license and Microsoft Exchange Online's useful features.

What's my experience with pricing, setup cost, and licensing?

The cost of our annual license for the solution is moderate. I would give the cost a five out of ten.

What other advice do I have?

I give the solution a seven out of ten. Microsoft Azure has experienced outages at times, but it can be comparable to Amazon Web Services (AWS).

I strongly suggest using Microsoft Office Exchange due to its ease of use and maintenance, as well as its increased reliability and added security features.

Which deployment model are you using for this solution?

Public Cloud

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

Useful sandbox feature; quite cheap
Pros and Cons
  • "It is a fantastic solution."
  • "In the next release, I would like to see more features added to the security of the solution."

What is our primary use case?

The primary use case for Exchange Online is managing users and their mailboxes, resources, and contacts. We also use it to manage email communication within and outside the organization.

How has it helped my organization?

Exchange Online has helped us properly manage email communications in the company and also from employees to other users outside the company. Microsoft has deployed a lot of newer features on Exchange Online that have helped improve security, email management, email trace, mail flows, and all else. This has been very helpful for us.

What is most valuable?

The features I find the most valuable are the rules, the mail flow, the reports, and the shared mailbox. I most appreciate the shared mailbox feature.

What needs improvement?

I think Microsoft could add more security features in terms of managing spam emails, because for us as an organization, we've had to deploy that trace to complement the Exchange Online security feature.

In the next release, I would like to see more features added to the security of the solution.

For how long have I used the solution?

I have been using Microsoft Exchange Online for over three years now.

What do I think about the stability of the solution?

I would rate the stability of this solution a 10, one a scale of one to 10, with one being not stable and 10 being very stable.

What do I think about the scalability of the solution?

I would rate the scalability of this solution a 10, one a scale of one to 10, with one being not scalable and all and 10 being very scalable.

We plan on increasing the usage of this solution in the future. As we increase the number of our employees, we also increase the usage of Exchange Online.

We currently have about 700 users and above.

How are customer service and support?

I would rate their customer service a 10, on a scale of one to 10, with one being very poor and 10 being very responsive.

How would you rate customer service and support?

Positive

How was the initial setup?

I would rate the initial setup a 10, on a scale of one to 10, with one being very complex and 10 being very straightforward. It was really straightforward.

What was our ROI?

We see a whole lot of return on investment.

What's my experience with pricing, setup cost, and licensing?

I would advise being aware of the organization's requirements. Also, an in-house technical person that can help in terms of managing is a necessity, because Exchange Online requires a continuous management process. The solution is not one that can just be deployed one-off and let go; it has to be continuously managed. Also, Exchange Online is quite cheap.

What other advice do I have?

Overall, I would rate Microsoft Exchange Online a 10, on a scale of one to 10, with one being poor and 10 being excellent. It is a fantastic solution.
