I am getting an event entry (Event ID 1052/Source:POP3 Connector) listed
below. This is happening every 15 minutes as scheduled. In addition it is
sending out the subject messages to people who have sent emails to one of
the accounts on the server. I can stop it by shutting down POP3, but need
to know how to find the offending messages to delete them.
The Microsoft Connector for POP3 Mailboxes will reattempt delivery of
message <id: {90824F3B-8433-4560-91FD-91923D9DB1FE}>. The message was
processed previously by the connector but could not be routed to the correct
recipient(s). If you continue to see this message, you should reinstall the
Microsoft Connector for POP3 Mailboxes. To do so, run Small Business Server
Setup again, and reinstall the Networking component.
