XCLN: Exchng32 Causes Invalid Page Fault on ThinkPads

• Microsoft Exchange Windows 95 client, versions 4.0 and 5.0

SYMPTOMS

When you run the Microsoft Exchange Windows 95 client on an IBM ThinkPad, you might see the following error when you exit Microsoft Exchange:

   EXCHNG32 caused an invalid page fault in module <unknown> at
   0000;10001b50

CAUSE

The ThinkPad has Collabra Share installed, an add-on extension for Microsoft Exchange. Collabra Share includes an extension DLL to automatically launch the application from the Microsoft Exchange toolbar. This DLL causes the error.

RESOLUTION

Exit the Microsoft Exchange client and use the Windows 95 Registry Editor (Regedit.exe) to find the following key in the Windows 95 registry:

   HKEY_LOCAL_MACHINE
      SOFTWARE
         Microsoft
            Exchange
               Client
                  Extensions

   QuickLaunch   "4.0;C:\COLLABRA\POLL95.DLL;1;01000000000001;111000"

MORE INFORMATION

For information about how to edit the registry, view the Changing Keys and Values online Help topic in Regedit.exe. Note that you should make a backup copy of the registry files (System.dat and User.dat) before you edit the registry.

WARNING: Using the Registry Editor incorrectly can cause serious problems

         that may require you to reinstall Windows 95. Microsoft cannot
         guarantee that problems resulting from the incorrect use of
         Registry Editor can be solved. Use Registry Editor at your own
         risk.
