TITLE   :XFOR: Notes Connector Crashes Processing Voice Mail Attachment
PRODUCT :Microsoft Exchange
PROD/VER:WinNT:5.5
OPER/SYS:
KEYWORDS:exc55sp2fix

SYMPTOMS
========

During normal operation while processing a voice mail attachment, the Microsoft
Exchange Notes Connector may terminate unexpectedly with an access violation. If
the correct Windows NT and Microsoft Exchange debug symbols are installed, the
resulting Dr. Watson log may have a stack dump similar to the following:

CAUSE
=====

The Octel Unified Messenger product sends voice mail messages as attached wave
files via Microsoft Exchange. The attachments of these messages do not contain
all expected information. When a Octel voice message was sent through the Notes
Connector, the Notes Connector did not handle the case where the attachment
information was not present and referenced a NULL pointer, resulting in the
access violation.

RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Exchange Server
version 5.5. For more information, please see the following article in the
Microsoft Knowledge Base:
