SYMPTOMS
========

During normal operation, when a message is being downloaded via POP3, the
Microsoft Exchange information store may terminate unexpectedly with an access
violation. If the correct Windows NT and Exchange Server debug symbols are
installed, the resulting Dr. Watson log may have a stack dump similar to the
following:

CAUSE
=====

A message containing an "x-user-defined" MIME character set with a code page
value of "50000" is being improperly handled by the information store. The code
page value of 50000 is not recognized by the store and, as a result, causes an
access violation.

RESOLUTION
==========

A supported fix that corrects this problem is now available from Microsoft, but
has not been fully regression-tested and should be applied only to systems
experiencing this specific problem. If you are not severely affected by this
specific problem, Microsoft recommends that you wait for the next Microsoft
Exchange Server version 5.0 service pack that contains this fix.

To resolve this problem immediately, contact Microsoft Product Support Services
to obtain the fix. For a complete list of Microsoft Product Support Services
