My primary use case is for email services.
Previously, we hosted our email servers with GoDaddy. We migrated the email addresses to Office 365 and we enabled mailboxes in Exchange Online.
Pros and Cons
- "It helps us manage the email focus from our side."
- "In the past, we had issues with DB in mailboxes."
What is our primary use case?
How has it helped my organization?
Previously, we hosted our email servers with GoDaddy. We migrated the email addresses to Office 365 and we enabled mailboxes in Exchange Online and we now manage the email focus from our side. I administrate this for our company through Microsoft Exchange.
What needs improvement?
There were prior issues with DB in the mailboxes. But, Microsoft has recently increased from 50 DB to 100 DB. So that is one of the nice recent changes from Microsoft.
For how long have I used the solution?
Three to five years.

manager of SAP department at Standard Sharing Software
Excellent email solution with EOP filtering service
Pros and Cons
- "There are many valuable features such as email, calendar, and the ability to share your calendar and documents with coworkers. Knowing that the emails go through the EOP filtering service is nice as well."
- "I would like to have the option to have my electronic signature posted on my emails by default. I am able to add it manually but cannot get it by default."
What is our primary use case?
I am an implementer of this solution. My clients use it as an email solution.
What is most valuable?
There are many valuable features such as email, calendar, and the ability to share your calendar and documents with coworkers. Knowing that the emails go through the EOP filtering service is nice as well.
What needs improvement?
I would like to have the option to have my electronic signature posted on my emails by default. I am able to add it manually but cannot get it by default.
What do I think about the stability of the solution?
It's a stable solution.
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

CEO at Enter++
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.

I recommend this product and rate it nine out of 10.

How was the initial setup?
The initial setup was not complex. There was a learning curve, but we overcame the challenge. We used the Microsoft website to help us with our questions.
What's my experience with pricing, setup cost, and licensing?
The pricing is a bit more expensive than other solutions.
Which other solutions did I evaluate?
We also have entities that use G Suite, and we have noticed that it is much smoother. We also considered IBM products, but we did not truly consider that as an option because of our Active Directory.
What other advice do I have?
I would like to let new users know that there are challenges regarding user provisioning, HRMS and the AD. Also, the data migration integrity needs to be checked in terms of the old data.
