When you use Outlook 2002 on Microsoft Windows 2000 Terminal Services, you may receive the following error message:
Outlook failed to start correctly last time. Starting Outlook in safe mode will help you correct or isolate a startup problem in order to successfully start the program. Some functionality may be disabled in this mode.
Do you want to start Outlook in safe mode?
If you click Yes
, Outlook 2002 starts. The next time that you start Outlook 2002, you do not receive the error message, but you do receive the error message the next time that you start Outlook 2002 after that. This loop of receiving the error message every other time that you start Outlook 2002 continues indefinitely.
This problem occurs because subkeys are written under the Resiliency
key and the Resiliency
key is not deleted if you have an unsuccessful startup test in Outlook 2002. If the Resiliency
key remains, you receive the error message that is referenced in the "Symptoms" section the next time that you start Outlook 2002.
The following is an example of how subkeys are written under the Resiliency
HKEY_LOCAL_MACHINE\Windows NT\Current Version\Terminal Server\Install\Software\Microsoft\Office\10.0\Outlook\Resiliency
with the TermSrvCopyKeyOnce
key having a value of 0x1 in the registry on the Windows 2000 Terminal Services in one of the subkeys under the Resiliency
When Outlook 2002 starts, the following registry key is created:
: The Resiliency
key for Microsoft Outlook is new for Outlook 2002.
If you do not experience any problems, the Resiliency
key is deleted. If one of the many tests that Outlook 2002 makes during startup fail, subkeys are written under the Resiliency
key and the Resiliency
key is not deleted.
If a subkey is deleted by a program from the HKEY_CURRENT_USER (HKCU)
registry key, specifically a subkey from the following registry key
while the server is in Terminal Server Install mode, the data is copied to the HKEY_LOCAL_MACHINE (HKLM)
registry key as in the following example:
HKLM\Software\Microsoft\Windows NT\Current Version\Terminal Server\Install\Software\\Microsoft\Office\10.0\Outlook\Resiliency
When the program tries to access the HKEY_CURRENT_USER\Software\Microsoft\Office\10.0\Outlook\Resiliency
registry key again while the server is in Terminal Server Application mode and finds it missing, the program looks in the HLKM location, specifically in HKLM\Software\Microsoft\Windows NT\Current Version\Terminal Server\Install\Software\\Microsoft\Office\10.0\Outlook\Resiliency
,for the key. If the Resiliency
key is there and has the TermSrvCopyKeyOnce
registry key under one of the subkeys of the Resiliency
key, the Resiliency
key is written back to HKCU.
In this case, the Resiliency
key was written with subkeys while in Terminal Server Install mode. After the terminal server goes back to Terminal Server Application mode, every user is affected because Outlook 2002 always looks for the Resiliency
key, and therefore causes the loop.
