We have migrated from Exchange 2003 to Exchange 2010. During the test phase, we imported 2 PST files from our old exchange server to our new one. Over a period of time this caused appears to have caused corruption to occur on the exchange database to which the PST files were imported. One of the effects was that a percentage of users were unable to download the OAB. we were able to resolve the problem by deleting all of the affected accounts and recreating them. Can I ask if anyone else has had these issues? I thought that maybe some of the mail messages were corrupt as when I tried to import mail using the exchange PowerShell, I had to use the bad mail limit switch. I understand that there’s a significant architecture change between exchange 2003 and Exchange 2010. Is it possible that the new Exchange mailboxes are expecting the mail in a different from format than the PST file is in?
Has anyone experience of corruption when importing PSTs to Exchange 2010 via the Outlook 2010 Client?
Your thoughts would be very much appreciated
