We have two email accounts set up in Outlook, both Gmail (Google Apps for Domains) accounts set up via IMAP. Over the last few days it seems as though Outlook is freezing up, turning gray, and becoming unresponsive. I've deleted both of the accounts and re-added them. They seem to work fine for a while (read: a few hours), but then begin causing the program to freeze up again. It seems as though the system is either in the middle of a Send/Receive when it freezes, or it happens when expanding the folder list for the IMAP account in the left pane. Outlook 2010 64 bit running on Windows 7 64 bit. We have another computer with a nearly identical setup that is experiencing no problems, and prior to the middle of last week this configuration has been working flawlessly on this system.
