We recently transitioned a client from Windows XP with Office-2003 to Windows-7 with Office 2010. Outlook transferred properly and was working for several days. Then, On Monday (Halloween) she started to lose her connection to the mail server and no emails will automatically download anymore. Send/Receive button does nothing. She has to "reconnect" and then manually send/receive to get messages in.
The account is an Google IMAP account. We did not change anything on Oct 31-Nov2 (the time when Outlook started misbehaving???)
