POP3SVC Error SBS 2003 R2
Hello folks,
We have SBS2003R2 Premium (using ISA) edition, and some email clients from branch offices are connecting to server through POP3. I am having this error in event viewer, but I have checked with branch office that they are able to receive emails without a problem.
ID1069, Source: POP3SVC
SSPI authentication attempt from <IP> has failed with error 0x8009030c.
What can be causing this? Thanks for all responses and tips.

Hello Perry,
Thanks very much for your info. However, we are having different error code as the one in KB article as you can see. I have read that article but that is not the issue.
- Users can login fine without issue, they download their mail into their Outlooks just fine
- This error is logged immediately after connection accepted message and after this error is a "client <IP> successfully logged on to mailbox <email address>
- I am not receiving relay error 550
- Security log also logs an "invalid username or password" error for affected pop3 user
Interestingly, I am not experiencing this issue with any other users or branches.
Thanks again,
Mike

Are you also receving a relay error 550?
If you are check that "Authenticate toward server for outgoing messages" is enabled on the clients side.
Also this might be usefull, its Microsofts artical on Users Cannot Log On Using POP3 and the Error 0x80040920 Is Logged.

Is this error logged when they try to send a message? I know some ISP's require you to use their SMTP server for all outgoing e-mail.
Cheers,
