Hi,

I recently added to my Outlook 2011 existing Exchange mailboxes (which work perfect) a couple of imap mailboxes. Now I get regularly popup messages with eg

Mail could not be received at this time.

The server for account "Gmail" returned the error "Logon failure: unknown user name or bad password." Your username/password or security settings may be incorrect. Would you like to try re-entering your password?

I already removed in Keychain the entries of the concerned mailboxes but this doesn't resolve the problem.

Can anyone help me on this, how to avoid these messages?

Thanks.
