How are customer service and support?
Microsoft always has nice support. You are able to create some tickets on the Microsoft support pop up, it's quite simple.
How was the initial setup?
On-premise setup for one server took about seven hours in total - I would expect this time to double, triple, etc. depending on the number of servers that you have.
I would expect cloud deployment to be significantly faster - maybe two hours for 100 email boxes.
What about the implementation team?
We used an in-house team of one senior engineer and one junior engineer.
What's my experience with pricing, setup cost, and licensing?
I think that the price is a little high, especially considering that Google have a similar, free email solution.
What other advice do I have?
If you are looking to deploy on-premise, make sure that you have a small data center, or even a small room for physical security. Otherwise, you should deploy Exchange online.
Which deployment model are you using for this solution?
On-premises

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

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.

A very good investment that's helpful for users
Pros and Cons
- "A good investment."
- "Documentation is lacking."
What is our primary use case?
Our company provides software and hardware as well as Microsoft product training. I'm the company CEO.
What is most valuable?
The solution is good for numerous deployments and helpful for many users.
What needs improvement?
Despite being a Microsoft-certified trainer, I am lacking some information. I don't know what each product does and how it is linked to other products. I'd like to see more updated documentation which is currently lacking. I'd like to see a smoother connection between Microsoft products and integration with other companies into the Exchange environment, particularly those that fill gaps in Microsoft. It's difficult to know where to get information for testing, tuning, and so on. I'd like some centralized way of logging.
For how long have I used the solution?
I've been using this solution for about 11 years.
What do I think about the stability of the solution?
The product is stable and provides good performance.
What's my experience with pricing, setup cost, and licensing?
I believe that the solution is not cheap but that it's a good investment. It's affordable but they've made licensing into a complex issue and it's difficult to try and follow all the changes.
What other advice do I have?
I recommend this product and rate it nine out of 10.
