I recently switched my outlook to use IMAP instead of POP for my work emails and have started having these two issues. I have these problems on two separate computers, one running WinXP with Office 2003 and another that I just bought brand-spankin' new with Windows Vista and Office 2007. 1) Outlook freezes when the connection to the server gets interrupted. 2) The little notification box that gives a preview of the message that just arrived will NOT show up and I have double-checked that it is enabled. The "new mail" icon appears in the system tray and Outlook plays the "new mail" sound, but the little preview box refuses to show up. Again, each of these problems happens on two separate machines that otherwise work perfectly and on the WinVista machine, I just downloaded a fresh copy of Office 2007 from MS's website. I have ONLY noticed this since switching my account to IMAP so it's got to have something to do with that - any ideas?
