SYMPTOMS

The MS Mail Connector Interchange (MSMI) may terminate unexpectedly with the following events reported to the application log:

Event ID: 2380

A memory access violation has occurred that prevents further processing of a message. The access violation that occurred is an attempt to read from 0x480df78.
