SYMPTOMS

When an Internet user sends an SMIME message to an Exchange Server recipient and requests a delivery receipt (DR), the Exchange Server information store may stop responding with the following information in the Drwtsn32.log and User.dmp files:

CAUSE

When the Exchange Server information store attempts to generate the DR, it incorrectly tries to free the same object twice. This results in an access violation, which causes the store to crash.
