I have 3 computers setup to send and receive IMAP/SMTP mail from my domain server using Outlook 2010, 2 with Win 7 and one with XP.
Everything was working up to 10 days ago, 19th Jan was the last email I received normally. Since then I cannot get the 2 Win 7 machines to receive my mail. The XP machine still works fine. The emails are on the server obviously or XP would not fetch them and I can see them in the web mail client. Sending test emails from the Win 7 machines is not a problem.
I have checked the account settings between XP and Win 7 and as expected they are identical. Last Windows Updates were installed on 13/Jan/2012 and the Win 7 machines were working after then.
Appears something else in Win 7 is at fault.
Thanks for any suggestions.
