It's a highly scalable, essential product for our business, but it could be more flexible and integration could be more seamless

- "Exchange Online plays a significant role in our business; it controls all our emails, so we'd be in a lot of trouble if we didn't have that, and it's an essential product."
- "The problem with Exchange is that the attributes aren't flexible enough. I'd like to see more interaction with Office 365 and tighter integration between on-prem Exchange and Exchange Online. There's still a disconnect between mailboxes and the cloud."
- "The problem with Exchange is that the attributes aren't flexible enough. I'd like to see more interaction with Office 365 and tighter integration between on-prem Exchange and Exchange Online."
What is our primary use case?
Exchange Online plays a significant role in our business. It controls all our emails, so we'd be in a lot of trouble if we didn't have that. It's an essential product.
What needs improvement?
The problem with Exchange is that the attributes aren't flexible enough. I'd like to see more interaction with Office 365 and tighter integration between on-prem Exchange and Exchange Online. There's still a disconnect between mailboxes and the cloud.
For how long have I used the solution?
I've been using Exchange Online for the last 20 years.
What do I think about the scalability of the solution?
Exchange Online is pretty scalable. We have about 6,000 users at our company.
How are customer service and support?
I rate Microsoft support six out of 10.
Which solution did I use previously and why did I switch?
We were using a Windows NT 3.5 20 years ago and an on-prem version of Exchange.
How was the initial setup?
Setting up Exchange Online is straightforward. I rate it eight out of 10 for ease of installation. The total time of deployment was a couple of days. I have eight staff looking after it.
What's my experience with pricing, setup cost, and licensing?
There's a licensing cost, but it's included in our Azure pricing, so I'm not really concerned about it.
What other advice do I have?
I rate Exchange Online seven out of 10. There's no alternative to it unless you want to use some Unix system, like Apache. People don't use Apache for wide-stream things like email and stuff like that. The only equivalent is a Linux-based or Unix-based solution, and who wants to do that?

Project Manager at Dell Technologies
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."
- "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.
Which deployment model are you using for this solution?
Public Cloud
