TITLE   :XFOR: IMC: Inbound Messages Queued but Not Processed
PRODUCT :Microsoft Exchange
PROD/VER:winnt:4.0
OPER/SYS:
KEYWORDS:kbusage

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Exchange Server, version 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

The Microsoft Exchange Internet Mail Connector (IMC) queues messages in the
Inbound Messages Awaiting Conversion queue. Messages stay in the queue and are
not processed. Incoming IMC mail appears to be stuck in the Exchsrvr\imcdata\in
directory.

CAUSE
=====

The IMC fails during specific Binhex conversions. That thread is effectively
looping during the conversion.

STATUS
======

Microsoft has confirmed this to be a problem in Microsoft Exchange Server
version 4.0. This problem was corrected in the latest Microsoft Exchange Server
U.S. Service Pack. For information on obtaining the Service Pack, query on the
