I recently has a problem with an Outlook plugin (or add-in) which caused outlook to crash. I couldn’t for the life of me uninstall the stupid thing. But I did manage to disable the add-in by doing the following:
- Quit Outlook.
- Click Start, click Run, type regedit, and then click OK.
- Locate and then click the following registry subkey:
You should be able to see all the addins for outlook. Just find the one you want.
Right-click LoadBehavior, and then click Modify.
In the Value data box, type 1, and then click OK.
Quit Registry Editor.
Start Outlook and the addin shouldn’t load.
It might be a good idea to take a back of your registry or make a system restore point before doing this – just in case you make a mistake or something goes wrong.
