XCON: Err Msg: EMS MDB Assert Failure

• Microsoft Exchange Server version 5.0

SYMPTOMS

When you copy a message from an attached PST file to the store, or re-send an old message while there are names in the Reply To field, you may receive the following error message:

   EMS MDB Assert Failure
   Thread 0x123, File 'M:\store\src\store\cp.cxx',Line 1529
   Assert(((fUnicode && cpidSrc == cpidUnicode) || (!fUnicode &&
   cpidSrc != cpidUnicode));

CAUSE

This problem may happen when you convert from an unknown SBCS code page to Unicode for existing messages with non-Unicode reply-to-entry IDs. There are two asserts involved. It is possible that the entry ID is in Unicode and the message containing it is not in Unicode.
