A stable solution with a good storage capacity
Pros and Cons
  • "It has helped us because we don't have to worry about servers crashing."
  • "The mail-blocking feature is not great and could be improved."

It has helped us because we don't have to worry about servers crashing. Everything has been stable since we began migrating to the cloud.

What is most valuable?

We have found the availability of large storage valuable.

What needs improvement?

The mail-blocking feature is not great and could be improved.

Convenient, easy to install, and scalable when deployed on the cloud, but has too many products integrated with it that it has now lost focus
Pros and Cons
  • "What I like about Microsoft Exchange Online is that it's a very convenient solution because it's part of the Microsoft business suite. This is the first email service I've used that lasted for many years, and I'm still using it because it's very convenient and it's suitable for my needs. Microsoft Exchange Online is the best product in the world for me because I don't remember any other service that's so well-accepted."
  • "What I don't like about Microsoft Exchange Online is too much integration because now it has many services connected to it. In the beginning, it was just email, and now it's also Teams and Visio, and many other services which I don't like. Microsoft Exchange Online should focus on one service. The product now lost focus, and this is its area for improvement. I would also like more freedom in choosing to use just one service, for example, just Microsoft Exchange Online, which means I don't need Teams or any other Microsoft product or service there. Right now, all services are either in the Microsoft Office suite, or there are more products or services integrated with Microsoft Exchange Online, and I'd like to just focus on one."
  • "What I don't like about Microsoft Exchange Online is too much integration because now it has many services connected to it."

What is our primary use case?

We're using Microsoft Exchange Online for our emails.

What is most valuable?

What I like about Microsoft Exchange Online is that it's a very convenient solution because it's part of the Microsoft business suite. This is the first email service I've used that lasted for many years, and I'm still using it because it's very convenient and it's suitable for my needs.

Microsoft Exchange Online is the best product in the world for me because I don't remember any other service that's so well-accepted.

What needs improvement?

What I don't like about Microsoft Exchange Online is too much integration because now it has many services connected to it. In the beginning, it was just email, and now it's also Teams and Visio, and many other services which I don't like.

Microsoft Exchange Online should focus on one service. The product now lost focus, and this is its area for improvement.

I would also like more freedom in choosing to use just one service, for example, just Microsoft Exchange Online, which means I don't need Teams or any other Microsoft product or service there. Right now, all services are either in the Microsoft Office suite, or there are more products or services integrated with Microsoft Exchange Online, and I'd like to just focus on one.

For how long have I used the solution?

I've been using Microsoft Exchange Online for more than ten years.

What do I think about the stability of the solution?

Microsoft Exchange Online is a stable product, in particular, when it's on the cloud. It's stable when it's dependent on the cloud, but if it's deployed on-premises, Microsoft Exchange Online is not stable.

It's a very old product with the same code, even on Windows. Nothing's changed, and my company is using Windows NT for Microsoft Exchange Online with Unix as the code.

What do I think about the scalability of the solution?

Microsoft Exchange Online is a scalable solution.

How are customer service and support?

We haven't used the technical support for Microsoft Exchange Online.

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

Microsoft Exchange Online is the first service I've used, and all the new services in the market are a little bit different from this solution. Microsoft is a very old company, and almost all of my colleagues started with Microsoft products, so it's just natural to continue using Microsoft Exchange Online.

How was the initial setup?

Microsoft Exchange Online is easy to install.

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

There is a license for Microsoft Exchange Online and I have information on that, but there have been so many changes to the licensing and it's a completely different story nowadays. Microsoft has been pushing users to buy a package of products under one license. Users are becoming more dependent on Microsoft rather than independent, that you can't decide anymore, and from my point of view, that is bad.

Which other solutions did I evaluate?

My company evaluated Qualitas, Unix, HP, and IBM.

What other advice do I have?

In my company, Microsoft Exchange Online is deployed both on the cloud and on-premises.

More than two thousand people use Microsoft Exchange Online in my company of four thousand employees.

At the moment, there's no plan of increasing usage of the product because of the current crisis.

In terms of whether I would recommend Microsoft Exchange Online to others, with the integration it has, it depends on the focus of the company. For small markets, Microsoft Exchange Online is "too big" because it has a lot of services and you'll be paying for services provided in the package, with some you don't get to use. For end users, this would be difficult, but for companies, especially bigger ones that would have a choice, Microsoft Exchange Online is a good product. My recommendation would depend on the case because every user is different, for example, the purpose is different, the business is different, etc.

My rating for Microsoft Exchange Online is seven out of ten.

Which deployment model are you using for this solution?

Hybrid Cloud

Features like SharePoint Online allow for collaboration between our team members
Pros and Cons
  • "We also create technical presentations, so most of the time we are dealing with MS Word and Excel. Sometimes, we also use Visio for diagramming. Our overall experience is good."
  • "Overall, technical support is very good."
  • "They should tighten their cloud security."

What is most valuable?

We use SharePoint Online for the collaboration of our team and for other desktop applications we are using in-house.

We also create technical presentations, so most of the time we are dealing with MS Word and Excel. Sometimes, we also use Visio for diagramming. Our overall experience is good.

What needs improvement?

They should tighten their cloud security. If you are using Microsoft Office 365, the responsibility of backup is not on the part of Microsoft. It is on the part of the customer. Microsoft Office should give some kind of built-in solution with the Office 365 subscription regarding the backup of their online mailboxes.

For how long have I used the solution?

My company has been a Microsoft Gold partner for the last 12 years. As soon as we became a Gold partner, we started to use Office 365.

What do I think about the stability of the solution?

It's stable.

What do I think about the scalability of the solution?

We can have different plans. If we are scaling, then obviously we can go for the enterprise plan and add an unlimited number of users to our Office 365 plan.

How are customer service and support?

Overall, technical support is very good. My colleagues reached out to Microsoft technical support many times for queries. They are very responsive.

How was the initial setup?

Setup was really simple. We migrated our customers from a different platform to Microsoft Office 365. There is a separate technical team. I designed the solution only.

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

They have raised their prices, and obviously, it hits our customers. Some of them are deciding to step back from Office 365. For customers who have bought the annual subscription, they are moving to the monthly subscription.

What other advice do I have?

I would rate this solution 8 out of 10.

I would recommend Office 365. It's a global product, and overall they have a larger footprint in the world. We're a Microsoft Gold partner, so as soon as the customer moves to Office 365, obviously our business will also grow.

Enables us to integrate with other Microsoft applications and use as a hybrid solution
Pros and Cons
  • "It's easy to use and there is more integration."
  • "Integration with the Microsoft applications is the key for us."
  • "The ActiveSync services and the mapping services could be improved."
  • "There are a lot of issues with security."

What is our primary use case?

I cannot put everything on 365 because it's obviously not as fast. We have Microsoft Exchange because we have a lot of emails. Most of our emails, about 80%, are on Exchange Server locally, and just 20% are on 365. We use Microsoft Exchange as a hybrid solution. The users who are accessing from outside and the users who are on our priority list outside of the organization are on 365. But the other people that are local are on Exchange Server.

There are more than 200 people using this solution in my organization.

What is most valuable?

It's easy to use and there is more integration. We have Dynamics and 365 as a hybrid solution. Integration with the Microsoft applications is the key for us. It has better integration with other solutions.

What needs improvement?

The ActiveSync services and the mapping services could be improved.

There are a lot of issues with security. We had one issue, a bug, with the Active Directory services.

The cost of the license could be lower, and the security features could be better.

For how long have I used the solution?

I've been using Microsoft Exchange since 2016.

What do I think about the stability of the solution?

It's quite stable.

It's a core product from Microsoft, so it's quite stable because of that.

What do I think about the scalability of the solution?

It's scalable. I chose this solution because it's easy to scale services. Services like Active Directory and ActiveSync aren't available in other solutions.

We don't have plans to increase usage right now.

How are customer service and support?

Technical support is good.

How was the initial setup?

Installation is easy. 

For installation, we have only two admins that can work on this solution.

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

The pricing is really high. It's higher compared to other services.

The license is yearly.

What other advice do I have?

I would rate this solution 8 out of 10.

An easy-to-use platform providing mail tagging and other top-notch security measures
Pros and Cons
  • "The solution is stable."
  • "The cost is very high, and not every customer can afford licenses."

What is our primary use case?

It's a messaging card with the assembly solutions. I manage multiple platforms and upgrade and migrate the environment on-prem to online.

What is most valuable?

It is an easy-to-use platform. It provides both browser-based and desktop versions, accessible through a single license or up to three licenses. Additionally, with enterprise plans, you can use desktop licenses. It includes mail tagging and other top-notch security measures. You can manage mailboxes and utilize many other features based on your needs. Shared mailboxes are also available and can be used freely.

What needs improvement?

The cost is very high, and not every customer can afford licenses. Many customers only require the desktop version, so they don't opt for desktop licensing. Also, Exchange lacks a tunneling system. We need to explore third-party solutions and tunneling systems.

They are improving the new version of Outlook. It's free, and we provide the desktop application. This can be quite resource-intensive on the desktop level. When you open Outlook, it heavily utilizes your internet connection, slowing down your email access. Another issue concerns security features. There have been reported bugs in Microsoft's security features where emails marked as spam may still get through, leading to concerns about spoofing.

For how long have I used the solution?

I have been using Microsoft Exchange Online for 11 years.

What do I think about the stability of the solution?

The solution is stable. However, some certain limitations and issues arise, particularly with the desktop application and related functionalities. Recently, Microsoft announced an issue with email invitations not functioning correctly in Exchange Online, leading to duplication and other disruptions.

What do I think about the scalability of the solution?

We must procure licenses and ensure we have everything required based on the requirements. However, this also depends on the network. For instance, scalability and other issues may arise if we have fifteen users and a network speed of ten Mbps from our ISP.

How are customer service and support?

I experienced an issue with Microsoft Exchange Online, where creations are typically sorted out within 15-16 days.

How was the initial setup?

I've worked on involved setting up Microsoft Exchange Online. We implemented DMARC, DKIM, and other essential email authentication protocols. Additionally, we focused on configuring API access to enhance security measures. We also redirected all mail services to Office 365, a standard procedure. Our approach included reconfiguring settings according to best practices for Exchange Online.

The deployment spans one month at maximum, depending on specific requirements. For me, it is crucial to meet all prerequisites, such as domain names, DMARC policies, certificates, and other necessary configurations. Once these are prepared, straightforward implementations can be completed within seven days, barring unforeseen complexities. Integration with licensing structures, email gateways, and potential hybrid environments adds further considerations. Understanding hybrid configurations is essential and tailored to meet client-specific needs for an optimal online deployment.

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

All of that is managed within the pipeline. The cost-saving aspect involves reducing licensing requirements. For instance, if you have fifteen licenses, you must evaluate which licenses are unnecessary for non-required production. Reducing those licenses will reduce costs.

What other advice do I have?

The compliance features are crucial. We have options such as rights management, marking as confidential, and restrictions on sending emails. Additionally, we monitor tunneling systems for security threats such as malware and employ spam filtering and anti-spam measures. These practices are designed based on industry best practices and tailored to meet customer requirements, including regulatory compliance. Retention policies are also implemented online for five to ten years, depending on customer and regulatory requirements.

It can be integrated using the Graph API. Third-party tools like IronPort and Mimecast can also be integrated with Exchange Online. These integrations often utilize Azure APIs for connectivity.

It requires maintenance based on our needs. Unnecessary licensing can become an issue, especially in large environments with multiple users. Therefore, it's essential to manage licenses effectively, such as by removing licenses from groups based on usage. Regular maintenance involves disabling users, removing sync, and adjusting licensing accordingly. Security features like spam filtering should also be upgraded quarterly to ensure optimal protection.

I recommend using Microsoft Exchange Online because it offers a straightforward environment. Administrative tasks are easily manageable at the L1 and L2 levels. However, it's important to note that Exchange Online operates primarily through a UI-based control interface. If issues like data corruption occur on the backend, we lack direct control to fix them ourselves. In such cases, we must report the issue to Microsoft for resolution.

Overall, I rate the solution a nine out of ten.
