Microsoft SBS 2003 and POP3 Connector – Onsite Observation

July 13, 2008

An Onsite client recently called for service as his SBS 2003 R2 Premium Edition stopped receiving email.  His SBS 2003 uses the included POP3 connector that is scheduled to receive mail from his ISP every 15 minutes.  The receiving process was flawless for years; however our client recently added a new employee and email reception halted shortly thereafter. 

Our client’s experience is obviously common as Microsoft has an article on troubleshooting the SBS 2003 connector.  Although the Microsoft article is helpful, our experience may save time and aggravation if you’re faced with the same problem.  A close examination of the last emails received can reveal clues to the cause of the failure.

The latest messages contained large attachments (> 7 megs each).  Apparently the POP3 connector could not receive all of the incoming messages within the fifteen minutes allocated to each connection cycle.  In the process of receiving the huge amounts of attachments, the connection cycle repeated and corruption resulted.  Not only were the large attachments corrupted, but also the Exchange POP3 connector experienced corruption.

A Google of the SBS POP3 connector reveals a plethora of systems experience the same problem; however attempts to reinstall the POP3 connector using IMBREG.EXE were not successful.  If you’re experiencing the same issue, we’ve discovered a temporary fix.  Instead of using the POP3 connector on the Exchange server, we configured the Outlook client on each PC to receive messages directly from the ISP.

Although this solution is not pretty, it works.  The Outlook clients receive all messages, including those with large attachments, without the corruption.  Stay tuned for a future post with our final solution to reinstalling the POP3 connector for the SBS Exchange server.
