OL2000: ActiveSync Error After Upgrading Outlook

ID: Q218384


The information in this article applies to:
  • Microsoft Outlook 2000


SYMPTOMS

When you reboot your computer after upgrading to Outlook 2000 you may receive the following error message:

ActiveSync cannot find critical Microsoft Outlook files. Please make sure Microsoft Outlook is installed correctly, and reinstall it if necessary. You may have a conflict with a folder named "\Program Files\Microsoft", which may have to be removed.


CAUSE

You had a Windows CE ActiveSync session running while you ran Setup. As long as a Windows CE device is connected, Outlook is running because the ActiveSync program holds a reference to the Outlook Object Model. Even though you quit Outlook prior to running Setup, Outlook is still running in the background while your Windows CE device is connected.


RESOLUTION

Quit Outlook and disconnect any Windows CE devices. Press CTRL+ALT+DEL and use the Close Program dialog box to verify that Outlook is not running in the background, and then start Setup to upgrade Outlook.


STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.
