I have a Gmail account set up with IMAP in Outlook 2010. Something went wrong awhile back. Gmail does not download (or synchronize) unless I click on the main folder to open the folder hierarchy and then click on inbox. It then downloads but very very slowly (and I usually only get a couple of emails per day via the Gmail account).
All of my other email accounts are listed in Outlook's accounts except the Gmail account. I cannot delete or close the Gmail folder hierarchy (pst file) because it tells me that I must remove the account from email accounts.
