When I sent test messages to her I didn't see any out-of-office replies.
Microsoft has a Knowledge Base article on the problem "You receive an error message when you try to start the Out of Office Assistant in Outlook 2003". That article recommends ensuring that no Outlook process is running and then checking the HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook registry key for a Resiliency subkey and, if it exists renaming it to Resiliency.old. A similar Knowledge Base article, Article ID 327353 recommends the same procedure if the problem occurs under Outlook 2002, though the registry key references 10.0 rather than 11.0 as the Outlook version. I don't know why Microsoft recommends renaming the Resiliency key rather than deleting it. There is no statement about restoring the orginal name afterwards. Perhaps Microsoft is suggesting renaming it in case deleting it doesn't resolve the problem or creates some other problem. There doesn't seem to be any reason for retaining the renamed subkey if renaming it removes the problem and Outlook works fine afterwards.
I did see a Resiliency subkey in the registry on the user's system. But in trying to understand the function of that subkey, I found another solution based on comments at Outlook / Disabled Items / Resiliency. The solution I employed was based on the information provided at that webpage. Since the solution doesn't involve editing the registry it is a procedure that can be employed by a user without risk of inadvertent damage to the registry.
To resolve the problem, you can take the following steps:
The items below were disabled because they prevented Outlook from functioning correctly.
Please note that you may have to restart Outlook for these changes to take place.
Select the ones you wish to re-enable.
You should then be able to click on Tools and then Out of Office Assistant to modify the out of office setting.
When I employed the procedure and then checked the registry
afterwords, there was no longer a Resiliency subkey.
The source of the problem is suggested on Josh Einstein's Web Log as being due to Outlook permanently disabling an addin:
If the AddIn experiences a problem during initialization, Outlook will prompt the user that the AddIn caused a problem and would you like to disable it. The user will of course always choose “yes” and this is where the problem starts.
Outlook creates a new item in HKCU\Software\Microsoft\Office\11.0\Outlook\Resiliency\DisabledItems that contains some cryptic hashed value of your AddIn. If your AddIn is listed here, forget about it! Outlook will not load it again. You can remove and reinstall the application as much as you like but that key never gets overwritten so the AddIn never gets loaded.
