Microsoft Exchange Online
January 2026
Learn what your peers think about Microsoft Exchange Online. Get advice and tips from experienced pros sharing their opinions. Updated: January 2026.
881,757 professionals have used our research since 2012.
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

Delivery manager at a computer software company with 201-500 employees
Completely scalable and flexible
Pros and Cons
- "The solution offers complete scalability and flexibility."
- "The solution should have more integration with other platforms."
What is our primary use case?
I use the latest version.
The solution obviates the need for infrastructure. The model is pay-per-use. We are not talking about a single email but a complete collaboration suite. One gets very well integrated IT which is tightly stitched with collaborations. One can chat and field calls. As such, it is not only Exchange Online coming on, but Office 365 Suites, which Microsoft provides the users. This availability ranges from first-line workers to CEO level users, depending on one's requirements. All the industry needs are covered. One can take the model best suited to him and tailor his solution to his investment capacity needs.
This means that the solution offers complete scalability and flexibility. A business user who occupies a very small portion of the industry can pay less for a suite. The desktop and web versions are also options. The solution's handy. One can use it on his mobile, or any other devices, including multiple devices and single identity. So, the picture is comprised of many components.
What needs improvement?
The solution should have more integration with other platforms. It is more integrated to the collaboration suite and other document management systems.
For how long have I used the solution?
I have been using Microsoft Exchange Online for the last couple of years.
What do I think about the scalability of the solution?
The solution boasts complete scalability.
How was the initial setup?
As the solution is cloud-based, there is no installation required. There is no need to worry about its applications and no license. We are talking about per-user subscription-based use.
When it comes to the license, we are already talking about Microsoft. There is also provisioning. Otherwise, it's just plug and play. There are not many administrative tasks involved.
What's my experience with pricing, setup cost, and licensing?
The model is one which is pay-per-use go. There is no license. We are talking about per-user subscription-based use.
When it comes to the license, we are already talking about Microsoft. There is also provisioning. Otherwise, it's just plug and play. There are not many administrative tasks involved.
A business user who occupies a very small portion of the industry can pay less for a suite. The desktop and web versions are also posibilities.
What other advice do I have?
The solution is an SaaS cloud-based solution.
There are a thousand-plus users making use of the solution in our organization.
I would recommend the solution to others, although this depends on the capacity one is interested in and whether he utilizes another solution. For someone who wants the complete bouquet of the solution, he can go with Office 365. There are others solutions which are geared to one who is only interested in email capabilities. There are many cloud-based solutions available, although these vary with the needs of the organization. Office 365 is geared towards someone who is looking for a complete collaboration suite. Someone who is not looking for this is advised to go with another solution.
I rate Microsoft Office Exchange as an eight to nine out of ten.
