I occasionally have the opposite problem - Outlook 2003/Btinternet premium mail service (POP3/SMTP) - in that I get a report that I could not get in and asking for my password again. Re-saving password makes no difference. It seems to affect only picking mail up, not sending in that I have never on such grounds seen mail sitting around waiting to send. It also affects only some but not all of the email addresses I am trying to pick up.
