When the information store attempts to process an inbound Simple Mail Transfer Protocol (SMTP) message, an access violation may occur. If you review the User.dmp file or if the proper Exchange 2000 symbols are installed at the time of the access violation, the Dr.Watson log file may contain a call stack that is similar to the following:
When the information store attempts to process an inbound SMTP message that contains a Transport-Neutral Encapsulation Format (TNEF) data attachment, the information store attempts to fully convert the message to Message Database Encapsulated Format (MDBEF) format in the information store, and then promote the message to the .edb file instead of leaving the message in native Multipurpose Internet Mail Extensions (MIME) format in the .stm file. This problem can occur if a PR_RTF_COMPRESSED property is present in the stream, but does not contain any Rich Text Format (RTF) data.
