SYMPTOMS

An incoming Internet Mail message causes the information store to crash.

Back to the top

Messages sent over the Internet are encoded at the sending end and decoded at the receiving end. If Base64 encoding is used and for some reason is corrupted or improperly encoded, the decoding logic in the information store causes an access violation, resulting in an information store crash.
