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:   FramePtr  RetAddr   Param1   Param2   Param3   Function Name 1438fcf4 00473eb6  00000000 0128cd6c 00000400 STORE!Cmnode::lpstrName 1438fd08 0047da5b  0128cd6c 0127b734 00000400 STORE!CmcvtrHdr::hrEmit+0x86 1438fd30 0047daed  01278f8c 00000400 1438fde0 STORE!CINETemtr::hrEmit+0xab 1438fd54 0047d950  01278f8c 00000400 1438fde0

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.

The English version of this fix should have the following file attributes or later:   Component: Information Store

File Name   Version Store.exe   5.0.1461.61 Mdbmsg.dll  5.0.1461.61
