885,376 professionals have used our research since 2012.
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?
Which deployment model are you using for this solution?
Hybrid Cloud
Disclosure: My company does not have a business relationship with this vendor other than being a customer.

Used for emails and provides integration with other services for shared calendars
Pros and Cons
- "The most valuable feature of the solution is its integration with Microsoft Outlook and Microsoft Teams for shared calendars."
- "The solution’s technical support could be improved."
What is our primary use case?
We use Microsoft Exchange Online for emails.
What is most valuable?
The most valuable feature of the solution is its integration with Microsoft Outlook and Microsoft Teams for shared calendars.
What needs improvement?
The solution’s technical support could be improved.
For how long have I used the solution?
I have been using Microsoft Exchange Online for two to three years.
What do I think about the stability of the solution?
We haven't faced any issues with the solution's stability.
I rate Microsoft Exchange Online an eight out of ten for stability.
How are customer service and support?
The solution's technical support is sometimes helpful and sometimes useless. It depends on the agent that is working on your case.
I rate the solution’s technical support a six or seven out of ten.
How would you rate customer service and support?
Neutral
Which solution did I use previously and why did I switch?
I previously worked with the IBM Domino mail system. Compared to the on-premises model of Microsoft Exchange Online, the IBM Domino mail system's maintenance and administration upgrades were less complicated.
How was the initial setup?
It wasn't difficult to migrate the solution from on-premises to the cloud. It took us around one week to migrate from on-premises to the cloud because we don't have that many mailboxes.
What's my experience with pricing, setup cost, and licensing?
We are Microsoft partners. We bought some licenses, and some are within our package or partnership with Microsoft.
What other advice do I have?
Earlier, we had the solution on-premises, and then we migrated to the cloud. The solution helped with the planning and time management within our organization by providing everything that Outlook offers to end users, including email and calendar.
The solution does not provide 100% security, and some emails are still detected as malicious by our other endpoint security solution. Microsoft Exchange Online does not require any maintenance from our side.
Overall, I rate the solution an eight out of ten.

Managing Director at ProQuanta
A stable solution for managing suites with a collaboration feature
Pros and Cons
- "One of the important features is the collaboration tool used in Office 365. The security and DLP mechanisms are also quite good."
- "The solution’s pricing could be better."
What is our primary use case?
We use the solution to manage calendars and the entire online and on-premises suite. It is used in large corporate banks.
What is most valuable?
One of the important features is the collaboration tool used in Office 365. The security and DLP mechanisms are also quite good.
What needs improvement?
The solution’s pricing could be better.
For how long have I used the solution?
I have been using Microsoft Exchange Online as a reseller for three to four years.
What do I think about the stability of the solution?
The collaboration speed has some issues, but it is stable.
I rate the solution’s stability an eight-point five out of ten.
What do I think about the scalability of the solution?
The solution is scalable. When you reach certain volumes, the default limits on the packages essentially allow you to use the full spectrum anyway.
The solution’s packaging makes it difficult to scale to the enterprise level without significantly upgrading the packages and negotiating higher limits on certain things, such as API calls, to accelerate data transfer.
Around 3000 users are using this platform.
I rate the solution’s scalability a nine out of ten.
How are customer service and support?
Microsoft technical support is making some improvements, but it can still be time-consuming to get an answer to a basic question. I often find it easier to troubleshoot the problem myself.
How was the initial setup?
The initial setup is straightforward and takes around a week to complete.
Exchange Online deployments can be complex, especially when migrating existing data from on-premises to the cloud. Much planning and preparation is involved, and the process can be lengthy.
What's my experience with pricing, setup cost, and licensing?
The product is expensive and has an annual subscription.
Which other solutions did I evaluate?
It's difficult to compare Exchange Online to other solutions because of its unique feature set and collaboration capabilities. For example, Google SaaS is quite limited compared to Exchange Online.
What other advice do I have?
We require a full-time team of four or five engineers across different divisions to look after this solution.
I recommend this solution. You’ll find it difficult to find a better solution with all the same features at the same price point. Most other competing solutions don't have the same feature set for the price.
Overall, I rate the solution an eight out of ten.
