As far as I can tell it's happening for SMTP and IMAP but not for POP. Unfortunately I don't have W8.1 let alone Outlook myself. And to reiterate, it only started happening after the most recent updates last week... I guess one of M$s regular "patch tuesday" updates. > It's true that there's not a lot to go by.

Looks like a generic error message... "It is very common to receive the error message 0x800CCC0E when configuring an email account in Outlook and trying to send an e-mail, the reason why you get the error is because Outlook is not authenticating your account on the server while sending it, so the outgoing mail server rejects the message." The advice is to set up "My server requires authentification" but all our users already have this set up. > The only way this can be investigated further, is have a controlled > environment with IMAGDEBUGFILE turned on, to capture what the client is > sending, and what the response is. Okay. I am waiting for the next client to call support with this problem so I can touch imaplog.dat and capture some IMAP transaction details. ------------------------------------------------------------------------------ One dashboard for servers and applications across Physical-Virtual-Cloud Widest out-of-the-box monitoring support with 50+ applications Performance metrics, stats and reports that give you Actionable Insights Deep dive visibility with transaction tracing using APM Insight. http://ad.doubleclick.net/ddm/clk/290420510;117567292;y _______________________________________________ courier-users mailing list courier-users@lists.sourceforge.net Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users
