Today i had problems with an old Antivirus add-in in outlook… the AV program had been uninstalled but outlook still tried to start the add-in.

Here are some places to look for and remove the add-in:

– Tools/Options/Other/Advanced options/ COM Addins or ADD-In Manager

– HKEY_LOCAL_MACHINESoftwareMicrosoftOffice OutlookAddins

– HKEY_CURRENT_USERSoftwareMicrosoftOffice OutlookAddins

Change it to load behavior 2 or delete the key.
