Integrated email security has improved phishing response and provides better threat visibility
Microsoft Exchange Online could be improved with more intuitive administration workflows, better troubleshooting visibility, and simpler mail flow analysis for complex environments. We would also appreciate more granular reporting, faster access to detailed message tracking data, and improved alerting around suspicious mailbox activity to help security and messaging teams investigate issues more efficiently. One area where Microsoft Exchange Online could improve is the administrative user experience. Some advanced mail flow, compliance, and troubleshooting tasks still require navigating multiple Microsoft portals. A more unified management interface and deeper integration visibility across Exchange, Defender, and Microsoft 365 security tools would make day-to-day operations more efficient for administrators and SOC teams.

Quick solution, but not very user-friendly or suitable for collaboration
It's not a good solution for collaboration. We're using it because of the price. It's not very strong or comparable with Office 365. An additional feature I would like to see is the ability to connect from different devices. Zimbra could be more user-friendly and deploy security rules. The integration with Outlook could be better to share agendas.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It allows us to work from home, at any time or anywhere."
"The most valuable feature of the solution is its integration with Microsoft Outlook and Microsoft Teams for shared calendars."
"It is for emails, and it seems to work okay."
"The solution is easy to use and the cloud version has taken a lot of challenges away from the user."
"We have found the solution to be stable."
"I chose Microsoft Exchange Online to cut this risk on our day-to-day operations for organizational communication with clients."
"The product is stable and provides good performance."
"One of the important features is the collaboration tool used in Office 365. The security and DLP mechanisms are also quite good."
"It's a fast solution."
"We implement this solution in our data centers, and we have high availability."
 

Cons

"I feel that there is a need for improvement in the product, considering that there are some concerns with the tool's integration capabilities."
"This product is too complex to use."
"For non-technical people, some configurations might be a little bit difficult."
"For example, recently there were some spam incidents that Microsoft does not currently mitigate because they have another paid solution to do so. It would be nice to integrate the security and the anti-spam (i.e. the fake links, etc.) along with the Exchange Online default."
"When you migrate from on-prem to cloud, if you choose to or are forced to do the hybrid, they need to devise a way to undo the hybrid."
"The SaaS platform performance could be improved. At a previous company, we used this same solution on-premises. The data exchange was much faster compared to the SaaS platform and we sometimes experience lags."
"We'd like to have the ability to recall emails on the web. I'm not sure if that is available yet."
"The interface is a bit confusing."
"It's not a good solution for collaboration. We're using it because of the price. It's not very strong or comparable with Office 365."
 

Pricing and Cost Advice

"The license for the solution is cheap, but it could be more affordable in the long term."
"I would give the cost a five out of ten."
"They have raised their prices, and obviously, it hits our customers. Some of them are deciding to step back from Office 365. For customers who have bought the annual subscription, they are moving to the monthly subscription."
"I have no opinion."
"Our organization pays for a corporate license to use the solution."
"We pay per user per year for the cluster with over a thousand users."
"We have a three-year license for $25,000."
"The cost of Microsoft Exchange Online is approximately $4 to $36 per user. They do not give a discount which is not good. The solution is expensive if you have 800 to 1,000 users. They should give discounts when you have a lot of users."
"It's an open-source solution so it's free."
