Outlook 2007 Crashes on Exit Due to WinFax Module dccmsp32.dll

Problem

I have a workstation running Windows XP SP2 on an SBS 2003 domain with Exchange. Yesterday I upgraded it from Office 2003 SP3 to Office 2007 SP1.  All security patches have been applied.
 
When logged on to this machine as an administrative user, Outlook crashes 100% consistently whenever I exit Outlook. Starting as “outlook.exe /safe” did not help. Running Office Diagnostics did not help.

Here is some information from the error that is sent to Microsoft:
 

Error signature

AppName: outlook.exe
AppVer: 12.0.63000.5000
appStamp: 4760725d
ModName: dccmsp32.dll
ModVer: 10.0.2000.929
ModStamp: 39d4133c
fDebug: 0
Offset: 00005346
 

Exception Information

Code: 0xc0000005
Flags: 0x00000000
Record: 0x0000000000000000
Address: 0x0000000010005346

The faulting module, dccmsp32.dll, is part of WinFax Pro 10.03. Disabling the Outlook integration on the WinFax side and the Outlook side did not solve the problem. 

Solution 

I eventually found this Symantec post:

How to integrate WinFax PRO 10.02 and Outlook 2002 on a limited basis
http://service1.symantec.com/support/faxprod.nsf/docid/2001110911391704

In the end, I wound up following the instructions at the very end of that document (“If the problems persist…”):  saving my Winfax data and cover subfolders, uninstalling WinFax, doing a Custom reinstall (deselecting External Phonebooks and send fax by email), copying my data and cover subfolders back, and renaming these four files:

C:\Program Files\Winfax\Wfxext.dll
C:\Program Files\Winfax\Wfoladin.dll
C:\Windows\system32\Dccmsp32.dll
C:\Windows\system32\
Dccwfp32.dll

After that, Outlook exits with no problems, and WinFax works by starting the Message Maanger (not the Controller).
