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

"Microsoft takes care of the back end while companies can focus on their day-to-day work and be more productive."
"The design is intuitive and better than the solution we had previously used, and once it was configured it was very easy to use."
"Exchange Online's best feature is its webmail platform."
"This solution makes it very easy to receive and detect problems about the mail flow and offers very good reporting. In general, it's very easy to manage the organization's mailboxes."
"Exchange Online is a straightforward cloud-based application. It's easy to connect and the interface is user friendly."
"The best thing about Microsoft Exchange Online is that it's integrated with the Outlook application."
"It is a reasonable solution."
"The features of Microsoft Exchange Online are very intuitive and well-built, keeping the user experience in mind. The usability and the accessibility are the best aspects of this solution."
"It's a fast solution."
"We implement this solution in our data centers, and we have high availability."
 

Cons

"I couldn't delete an email account because it was identified as my primary account by the application."
"Microsoft Exchange Online support can be optimized further. They should put some more efficient technical engineers to support end customers."
"The solution could improve by making the user interface better."
"Also, I think the mobile app on the forms you can improve a little bit more."
"The price of the solution could be less expensive."
"My personal issue with using OfficeSuite and the Exchange Server is that one has to cobble together a whole bunch of different applications. Therefore, a lot of scripting and programming knowledge is necessary."
"In the past, we had issues with DB in mailboxes."
"Functionality wise, I can't really say it's improved from Exchange Online, I think it's not so much change on-premise. It's about the same. Other than that, it's the extra features that make a difference, really"
"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

"I would say the solution is reasonable and affordable."
"Microsoft Exchange Online is too expensive."
"The price is a bit high. It is especially expensive in the Indian market."
"We have a license per user scenario."
"There is an annual enterprise subscription to use Microsoft Exchange Online. The price is reasonable."
"The pricing for Microsoft Exchange Online is quite reasonable, in my opinion. Many licensing options are available so that we can choose based on the customer's needs. For example, if a customer only requires mailbox features, we can recommend Plan One or Plan 2. We can suggest an E3 or E5 license if they need the entire Office suite. There are also premium subscriptions for enterprise customers, offering additional security features. Overall, I don't find the pricing costly because Microsoft provides many features and security capabilities, making it reliable for all customers, depending on their requirements."
"We bought some licenses, and some are within our package or partnership with Microsoft."
"This is an expensive solution."
"It's an open-source solution so it's free."
