I've just migrated from Small Business Server 2003 to SBS 2008. Things were going fine until Iset upa POP3 connector. It just won't work. I get an error in the event log with an Event ID 203. Message Text:An error occurred while delivering mail to 'Rick@libertywrites.com' on the SMTP server 'localhost'. The error code was 0x800ccc69. Verify that the mailbox exists and that the Exchange receive connectors are configured properly.The mailbox does exist, and an online search on any of the keyword/numbers gets no hits. I've checked the POP3 parameters, and they're all correct.Where do I look next?
