Hi, my users calendars periodically goes 'missing' in chunks. Firstly we thought we solved the issue as the aqnti virus solution was scanning the exchange folders, and after we stopped that it didn't happen for a while. But today this issue has reared it's ugly head again. We are running Exchange 2003 SP2 with Outlook 2003. Has anybody experienced similar issues? Many Thanks, Lee

Hi, Any events logged on the exchange server that might help resolve this issue? Leif

Hi, For solving the problem better, you should provide more information, such as log records, cached Exchange mode versus online mode and so on. You can refer to the following article ‘Working with support to troubleshoot the Outlook calendar in an Exchange environment’.
