Great for collaboration and syncing calendars with good reliability
Pros and Cons
  • "The solution has been stable with good performance on offer."
  • "Microsoft takes care of the back end while companies can focus on their day-to-day work and be more productive."
  • "The solution could be a bit cheaper."

What is our primary use case?

We use Microsoft Exchange for sending emails and running calendars. With the calendars, we are able to check other people's calendars and be sure of their availability so that they can deploy solutions. That's what we normally use it for.

What is most valuable?

The solution is great for collaboration purposes. 

The calendar capabilities are great.

The solution has been stable with good performance on offer.

The product can scale. 

What needs improvement?

The solution could be a bit cheaper. 

I'd like it to be more voice-activated and to have more AI so that it becomes easier to use. The world is moving toward more AI and machine learning, and likely they will adopt more of it in the future. 

For how long have I used the solution?

We just migrated to the solution. We've used it maybe for about a year and a half so far.

What do I think about the stability of the solution?

The solution is very stable and reliable. There are no bugs or glitches. It doesn't crash or freeze. 

What do I think about the scalability of the solution?

I've not had any problem with it personally in terms of scaling. Due to the fact that it's connected, it pulls everything down. I'm able to do whatever is needed of me with it without stress. 

Everybody is using it now in the company. If it was not scalable, I don't believe over 100,000 staff members could be using it without issues. It has to be scalable.

If we want to increase usage, we simply purchase more licenses. 

How are customer service and support?

I've not had any contact with tech support. It's been very stable for me. There has been no need.

How was the initial setup?

I'm not part of the team that does the installation. That said, I know that Exchange should be good in terms of implementation. In the mailing lists that I used to install, the installation was straightforward. If you get your configurations right, it works. It works well without any trouble. This is Mircosoft. I'm sure it's fine to install.

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

You do need to pay a licensing fee in order to access the solution. There are also enterprise agreements where companies would have to agree to a certain level of volume. 

It could be less expensive. If it was, more companies would use it. 

What other advice do I have?

I'm an end-user.

I would recommend the solution to others and rate it at a ten out of ten. It's in the Cloud; people don't need to have anything on-site or to worry themselves with problems any longer. Microsoft takes care of the back end while companies can focus on their day-to-day work and be more productive.

Simple, easy to use, scalable, and easy to install
Pros and Cons
  • "Microsoft Exchange Online is very simple and easy to use."
  • "For non-technical people, some configurations might be a little bit difficult. We can use it on our laptops or our portable devices like mobiles and others gadgets, but we have had repeated problems with syncing. That is, when using different gadgets and devices, there are issues with syncing. The configuration could definitely be improved."
  • "For non-technical people, some configurations might be a little bit difficult."

What is our primary use case?

We use SharePoint and Active Directory, meaning that all telecom users and customers are authenticated. We use it as a gateway.

What is most valuable?

Microsoft Exchange Online is very simple and easy to use.

What needs improvement?

For non-technical people, some configurations might be a little bit difficult. We can use it on our laptops or our portable devices like mobiles and others gadgets, but we have had repeated problems with syncing. That is, when using different gadgets and devices, there are issues with syncing. The configuration could definitely be improved.

Technical support is needed for any log-in credential problems and other related issues.

For how long have I used the solution?

I've been using it since 2008.

What do I think about the scalability of the solution?

It is scalable. We have around 16,000 users in our company.

How was the initial setup?

There are no problems with the installation, but when you finish the installation and get to the authentication part of the log-in, there may be problems. It needs improvement.

A team of not more than ten is needed for deployment and maintenance.

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

We have yearly licensing costs.

What other advice do I have?

I would rate Microsoft Exchange Online at eight on a scale from one to ten.

Reduces maintenance, has zero downtime and is fairly reliable
Pros and Cons
  • "I enjoy not having to maintain the local infrastructure, local servers, local whatever. You use the software and don't have to worry about the details."
  • "I don't really like the response time of the web GUI for administration. All this seems a bit slow and not responsive enough."

What is most valuable?

The experience has been rather good. We've had nothing major happen to us. We've had no major downtimes. We haven't lost mail so far, which is good.

I enjoy not having to maintain the local infrastructure, local servers, local whatever. You use the software and don't have to worry about the details. You're not concerned with administration tasks other than managing users, which, of course, our team does on a daily basis, basically.

The pricing is okay.

The solution is stable.

The product scales well.

The user interface isn't too bad.

What needs improvement?

There were a few short outages where mail delivery was flaky.

I don't really like the response time of the web GUI for administration. All this seems a bit slow and not responsive enough. They should provide a far simpler solution for sending mail from machines as this is not really intuitive.

Due to the restrictions that Azure and Microsoft impose on sending mail, for example, if you have an Azure-deployed server that is sending out mails (for a shop system or something like that) it's not really simple. Also, it is not really scalable to use Office 365 as a relay server.

There's not really a useful backup tool that comes along with Exchange Online. You have lots and lots of storage for each user, yet you have to buy extra backup tools just to back it up with an Exchange on-premise. You could do this just with onboard tools, however, there's no such thing in cloud deployment.

For how long have I used the solution?

We completed the migration from Lotus Notes on-premise to Microsoft Office Online or Exchange Online last year.

What do I think about the stability of the solution?

The stability has been good. We haven't dealt with bugs or glitches. it's pretty reliable. 

What do I think about the scalability of the solution?

I expect the product to scale well. That is what we are paying Microsoft quite a bit of money for. They have to address scalability, reliability, and things like that. We have the service-level agreement and it's their business to do it. That's what they get the money for. 

We have about 3,500 physical users currently using Exchange. There are 1,500 more that are not interactive (for example, service accounts, group mailboxes, and accounts for machines that send mail and things like that). That makes the total number of users 3,500 persons and about 1,200-1,500 users that are not necessarily people.

How are customer service and support?

I haven't had any direct contact with technical support, however, I have not heard complaints as to their services.

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

We used to have an on-premise deployment of Lotus Notes, however, we discontinued using this and swapped over to Microsoft Exchange Online with the help of an external consultant as there was a lot of mailbox migration to do. That was a quite lengthy process due to the fact that we had several terabytes of mail storage that had to be migrated.

How was the initial setup?

We had a partner help us migrate everything over. 

The deployment times depend on a few factors. From the first start to the last migrated mailbox, for us, the deployment took over half a year. That said, actually, it wasn't that long, as we deployed in several waves taking one user group at a time and migrating them over.

Therefore, the real transfer time was much less than the seven months. In total, if you take the net time, it might have only been one month of actual migration.  However, we made a point of migrating only on weekends to keep user satisfaction high and disturbance to daily business low.

What about the implementation team?

We had a partner assist us with the process.

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

Pricing is good. However, it's also not exactly cheap.

It's my understanding that we have a contract that runs for two or three years with an enterprise agreement backing all this up. We do not buy on a yearly basis. That would be unusual for our company to buy for such short term.

What other advice do I have?

Since the project was finished, I'm no longer in an administrative role with Exchange Online. I have passed it on to other colleagues. The administration part is no longer in my hands, for which I'm quite grateful. I don't have to do the daily tasks anymore. My main job is to be the principal cloud architect for the company. I'm, to a lesser extent, concerned with daily administration tasks.

I'd recommend potential new users just go ahead and do it. It reduces the on-site administration chores by quite a bit. It's reliable enough to be used without second thoughts for business if you can handle the cost that comes with it, as Exchange or the whole Office 365 is not exactly cheap, especially when you count in the cost for security-related services that come with Office 365 if you pay for them.

I'd rate the solution at an eight out of ten. It works well, just not perfectly.

Useful mail flows, stable, and simple installation
Pros and Cons
  • "All of the Microsoft Exchange Online is very useful, such as the sections, the information protection, and the mail flows."
  • "The solution could improve with the integrations with some of the known applications is still not possible, there must be more connectors."

What is our primary use case?

We use Microsoft Exchange Online for emails and communication.

What is most valuable?

All of the Microsoft Exchange Online is very useful, such as the sections, the information protection, and the mail flows.

What needs improvement?

The solution could improve with the integrations with some of the known applications is still not possible, there must be more connectors.

There should be a feature when sending the emails it pops up and gives the confirmation of the real details when you are sending them out outside. There's an option for the alerts, but there's no double-check. We cannot double-check it or re-confirm it again. This option would be nice to have.

For how long have I used the solution?

I have been using Microsoft Exchange Online for approximately two years.

What do I think about the stability of the solution?

I have found Microsoft Exchange Online to be stable. I have not had any issues.

What do I think about the scalability of the solution?

Microsoft Exchange Online is scalable.

How are customer service and support?

I have not needed the support. 

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

I have used Gmail previously, but I like Microsoft products better. The options and features are already at the granular level.

How was the initial setup?

The installation is simple.

What about the implementation team?

I did the implementation of the solution myself.

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

I am using Office 365 and Microsoft Exchange Online comes as the package. It cost approximately $13 per month.

What other advice do I have?

We have a lot of connectors with Office 365, and it's integrated with Microsoft technologies already. Additionally, there is integration with other third parties solutions. It's a good product.

I rate Microsoft Exchange Online a ten out of ten.

Great security flow, easy to set up, reasonably priced
Pros and Cons
  • "The initial setup is straightforward and is definitely easy."
  • "Compared to the competitors, I would say it gives you a lot more functionality and is easy to integrate with other applications and tools."
  • "Technical support can be improved by shortening the response time and increasing their knowledge."

What is our primary use case?

The primary use case of the solution is mainly used for our email conversation, specifically for minutes of meeting or to propose a solution.

What is most valuable?

The most valuable features of the solution are the security of the email flow, the primary security, having a dedicated, consultative space where if I send an email from a billing app or from a browser or anywhere, it gets stored in consultative space, and some of the end users features such as Word solution.

What needs improvement?

Technical support can be improved by shortening the response time and increasing their knowledge. The solution can improve the integration with mobile applications.

For how long have I used the solution?

I have been using the solution for over ten years.

What do I think about the stability of the solution?

The solution is stable.

What do I think about the scalability of the solution?

The solution is scalable.

How are customer service and support?

The technical support is completely based on how we connect with the support team. I would say they just follow the ticketing process. I do have mixed feelings because it's completely based on the engineer allocated to my ticket. Depending on who you get some are more knowledgeable than others.

How would you rate customer service and support?

Neutral

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

  • Technical support can be improved by shortening the response time and increasing their knowledge.

How was the initial setup?

The initial setup is straightforward and is definitely easy. Anyone with basic IT knowledge should be able to do it.

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

I would say the solution is reasonable and affordable. Compared to the competitors, I would say it gives you a lot more functionality and is easy to integrate with other applications and tools. I give the solution ten out of ten for pricing.

What other advice do I have?

I give the solution nine out of ten.

We currently have between six and seven thousand daily users.

The solution 

The solution doesn't require any maintenance. The solution is a cloud platform and everything is taken care of by Microsoft, so there is no maintenance required. It's maintenance-free.

I recommend the solution. As soon as you know what your needs are, you can go ahead with Microsoft Exchange Online. You don't need any demonstration of features, and you don't need to do any POCs.

I think the solution is pretty reasonable in what it does. In terms of mobile applications, that is Microsoft Outlook for Android and iOS integration, which can make some integration to Microsoft Teams application, which is already prospected in the desktop application. If they can have it in mobile application also, that would be good. But as a solution, I couldn't think of any new features that are required presently.

Which deployment model are you using for this solution?

Private Cloud

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