On outlook I have 3 email accounts, 2 IMAP and 1 smtp. All have worked fine until last night when 1 of the imap accounts came up with the above error on sending an email (it receives ok on that account and the other IMAP account with the same providor is fine).
I've run it through google but the problems posted, with this error number, doesn't fit my scenario.
I've tried using Opera to send mail on the same account and this sends no problem so it must be an Outlook issue, all the settings look OK.
Yes I did but the articles found didn't really cover my problem - mine is an isolated problem with 1 account whilst the articles suggested a problem with all accounts. I have deleted and recreated the account to no avail.
Thanks i tried that and compared the settings of the problem imap account with that of the imap account thats working OK - exactly the same (suppose that rules out the firewall/AV asboth imap accounts have the same settings.
