I have just upgraded 20 users from Outlook 2000 to Outlook 2003, and one of them now gets the above mentioned error when starting Outlook. Ass upgrades were done by letting Setup remove outlook 2000 and install 2003 in its place. When starting outlook, she sees the Windows Installer window first, with a message to "Please wait while Windows configures Outlook" and a progress bar. This window replays anywhere from three to six times, and then Outlook starts. Immediately after the Outlook window paints, the error pops up. After clicking OK, Outlook runs normally.
Any thoughts on what could be causing this? There is nothing in the Add-in Directory.
Thanks for any help you can offer.
