John,
I don't believe that's a file installed by Office/Outlook. So, my guess is
that you have an Outlook add-in that's causing this problem. Please do the
following steps to confirm this assumption:
1. Exit Outlook.
2. Press and hold the CTRL key as you launch Outlook.
3. When prompted to start in Safe mode click Yes.
Does the error occur? If not, please continue with the following steps:
1. Exit Outlook.
2. Start Outlook in normal mode (don't hold down the CTRL key).
3. On the Tools menu click Options.
4. On the Other tab click Advanced Options.
5. Click Add-in Manager.
6. Note the list of add-ins with a check in the checkbox. If you see
anything that does not have "Delegate" or "Exchange" in its name, clear the
checkbox and restart Outlook.
7. If the error does not occur then you would need to figure out which of
the currently disabled add-ins was causing the error.
Hope this helps.
