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

"My primary use case for this solution is for clumping emails, and group emails according to the conversation."
"The user experience is very fantastic for Microsoft Exchange Online currently; I am satisfied with the integrations available with other Microsoft products, and Microsoft Exchange Online has great security features and the spam filters work super fine."
"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."
"All of the features are beneficial, but the scheduling feature is particularly useful."
"The solution is easy to access, and you can bring your own device to access from anywhere."
"Microsoft Exchange Online's resiliency is its most valuable feature."
"This means that the solution offers complete scalability and flexibility."
"I enjoy not having to maintain the local infrastructure, local servers, local whatever. You use the software and don't have to worry about the details."
"It's a fast solution."
"We implement this solution in our data centers, and we have high availability."
 

Cons

"I have found that Microsoft has vulnerabilities when it comes to Exchange Online. It has become the port of a lot of hacker attacks."
"It should integrate better with social media formats."
"In the next release, I would like to see more features added to the security of the solution."
"Tech support is a challenge at times. They take a long time to respond."
"The pricing could be a bit lower."
"The price of the solution could be less expensive."
"In terms of areas for improvement, I think Microsoft could enhance security. Right now, there are limited options for security within Exchange Online, and much of it relies on third-party security and compliance tools. I'd like to see more security features directly integrated. One specific area that needs improvement is the configuration of SMTP for third-party applications. It's challenging to manage without an on-premise SMTP server, and this is an issue many organizations face, including ours. If Microsoft could offer better SMTP configuration for third-party applications within Exchange Online, it would greatly benefit us."
"The mail-blocking feature is not great and could be improved."
"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 costs of this platform vary based on subscriptions, but it is generally reasonable."
"I have no opinion."
"The model is one which is pay-per-use go. There is no license. We are talking about per-user subscription-based use."
"We pay a yearly licensing fee for the solution."
"The product is expensive and has an annual subscription."
"The pricing could be improved."
"The price is a bit high. It is especially expensive in the Indian market."
"The pricing is really high. It's higher compared to other services."
"It's an open-source solution so it's free."
