"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

This clearly shows that you have a faulty add-in installed. Run Outlook in safe mode using the following command:
outlook.exe /safe

Open in new window

If the error is gone, disable installed Outlook add-ins one by one to find the faulty one.

This is more an OS issue. Looks like .net is corrupt. On PC run this command.

Open CMD in admin mode and type

sfc /scannow
