XCLN: Invalid Page Fault in Mapi32.dll

• Microsoft Exchange Windows 3.x client, version 4.0
• Microsoft Exchange Windows NT client, version 4.0
• Microsoft Exchange for Windows 95, version 4.0

SYMPTOMS

When you use the Simple MAPI function MAPISendMail(), its data structure contains a Cc: recipient, the MAPI_DIALOG flag is set, and the simple SendNote UI is turned ON, the client or application calling this function might generate an invalid page fault or general protection fault in module Mapi32.dll.

CAUSE

A parameter that is passed into the function that displays the Send Note UI is incorrectly set to NULL and this causes the fault in Mapi32.dll

WORKAROUND

Do not set the MAPISendMail() MAPI_DIALOG flag, do not turn on the simple SendNote UI flag, or do not include a Cc: recipient.
