This is Outlook 2010 connected to Exchange 2008 on an SBS2008 server
We upgraded a workstation. Previously it was Vista with Outlook 2007. The user had a 900Meg .PST file with his archived emails.
Outlook 2010 seemed to be working ok until I attached this .PST file. Then it hung completely. I went back to the old machine and copied the archive emails back into his main mailbox again. Then in Outlook 2010 I created a new .PST file and tried to move the emails into it. It crashed again.
Is there a known problem with Outlook 2010 and .PST files?
