  3. Click Go
  4. Uncheck the add-ins you want to disable

Administrator Rights

For some add-ins you may receive the following error when disabling:

“The connected state of Office Add-Ins registered in HKEY_LOCAL_MACHINE cannot be changed.”

This indicates that Administrator rights are required to disable:
  • Windows Vista - Close Outlook, right click the Outlook shortcut in the start bar, select Run As Administrator, enter your credentials and disable per the instructions above
  • Windows XP - Log into your PC as an Administrator, make the changes above, log back in under your own account

Please see our list of known add-in conflicts if you are experiencing an issue with another Outlook add-in. If you're add-in isn't listed, please post the issue you are having in our forums. Thanks!
