After installing an add-in (.xla) which worked once, I'm trying to remove it so I can install an updated version.

So far I've:

  • deleted the .xla
  • removed the check box in Tools > Add-ins
  • removed it from the list
  • Quit Excel completely
  • reopened Excel.

I get an error that Excel can't find the plugin, it's back in the Add-ons list, and the Add-ins toolbar is still there with the Add-ins buttons.

Did all the same stuff again, this time with a reboot thrown in. No change.

Where is it storing this? I looked through the plists in the Excel bundle, but couldn't find any references.

You have to do this through "My Add-Ins"

In the Insert Menu, select Add-Ins and then the submenu "My Add-Ins"

Click the 3 dots in the upper right hand corner of the Add-In you wish to remove. Then click "Remove".

  • Thanks - you may get a warning (yellow bar with text) telling you that the add on could not be deleted and to try again. Simply hit REFRESH and it should show you a list off add on's you still have active minus the one's you removed. Apr 9, 2018 at 9:24
  1. In Excel, choose Tools>Templates and Add-ins.
  2. In the Global Templates and Add-ins section, select the problem add-in. Make a note of its location under Full path:, then close Excel.
  3. In the Finder, hold down the Alt key while clicking on the Go menu and choosing Library. Your user library folder will open. Navigate to the path you noted in the last step.
  4. Delete the add-in file.
  5. Restart Excel and check that you've gotten rid of it.

For Outlook on Mac, Go to top toolbar 'Get Add-ins'-->'My add-ins'--> Click the ... button to see the remove add-in option. enter image description here


If you're looking for the Zoom / RingCentral add-in for Outlook for Mac, you need a different method.

From https://apple.stackexchange.com/a/372659/113440 ...

The zoom plug-in / add-in is not provided by the Microsoft store, rather installed by zoom itself, so you won't find it in the Microsoft store > my add-ins area. If you go to finder > applications, you will see a folder called 'Zoom plugin for Outlook', in that folder is an uninstall icon. Close outlook, uninstall, and voila....zoom gone!

This has been especially important since the zoom client no longer works in macOS Catalina, so it's useless to keep it in outlook.
