I have the following environment
Exchange 2003 - Ver. 6.5 Build 7638.2: Service Pack 2) 3 Storage Groups, 14 Mailbox Databases
Outlook 2003 - 11.8206.8202 SP3
CDO.DLL and MAPI32.DLL are same version on BES and Exchange 2003 and are registered.
If I put an appointment on a calendar within about a half hour it moves from the calendar to the deleted items. I can sit and watch it happen. It is not across the board but is happening to 2 users in 2 separate databases in 2 different storage groups.
I know that Exchange does not simply delete an appointment out of boredom so I have tried a few different things as follows:
opened outlook with the extensions \cleanrules - \cleanfreebusy - and lastly \clearview
blew away users outlook profile and created a new one
Users are not running in cached mode.
My next step is to take the 2 impacted databases offline and run a defrag on them, as well as re-register CDO.DLL and MAPI32.DLL on my exchange server and BES and then restart both boxes.
I am at a loss here, and am turning to the EXPERTS here to lend some advice. HELP!!!!!
