Exchange 2007 running on SBS2008. We have approx 10 user mailboxes set up in Exchange, each with their own pop3 connector. All has been well for 2 years until today suddenly one user stopped getting their email in (still sending out ok). Went into SBS Console pop connector, all looks ok. Tried Retrieve Now under Scheduling and an I'm prompted to check Event Viewer for errors. In there I see the following:
Event ID 203: An error occurred while delivering mail to '<firstname.lastname@example.org>' on the SMTP server 'localhost'. The error code was 0x800ccc67. Verify that the mailbox exists and that the Exchange receive connectors are configured properly.
Wow! What does that mean and what should I be looking for and where?
All other users' mail is flowing in fine, the issue is only afflicting the one mailbox.
Everything looks good in the POP3 connector screen. Worth deleting & re-creating the connector for this mailbox or what?
