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.
