The front end of the databases on the home screen looks somewhat old-fashioned.

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.

IT Director at ATOS
Has improved email security through built-in encryption and supported offline work effectively
We don't use team workspace with HCL Notes; we use only Microsoft because it's incorporated with the Microsoft license. Based on my extensive experience with HCL Notes, I think HCL can make its product better by being more visible on the market because most companies don't support or use HCL anymore, and most integrators work with Exchange or Outlook rather than HCL Notes. Inside HCL Notes functionality, they have to be more visible in the market, which is very important.
Yogesh Autade - PeerSpot reviewer
Senior Security Engineer at Softcell Technologies Limited
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.
