We are running Exchange server 2003 and Outlook 2003 clients running Win XP SP2. So far I have tried the following: Removed ‘Cached Exchange Mode’ from the account Removed Cached Exchange Mode, removing the user’s .OST file and then restarting Outlook to re-populate the mailbox and create a new .OST file. This seemed to calm things down for a few days but the problem is back again, I haven’t tried removing and re-installing MS Office, but this might be my next step, anyone got any other idea’s?
