Add-in can only be Disabled by an Administrator

› Problems › Add-in can only be Disabled by an Administrator

The Problem

When you attempt to remove an add-in, the dialog tells you that only an administrator can connect or disconnect the add-in:

This add-in is installed for all users on this computer and can only be connected or disconnected by an administrator.

Add-in is installed for all users

The Cause

Trying to remove an add-in that was installed using the option “All users” will result in this error message. If the add-in was installed for the current user this message will not appear.

When you install software, the screen may have an option to install it for the current user or for all users of the computer as is shown on this screenshot.

Most users click Next without paying much attention to this screen (using the default set by the developer), or set it for "All users" so the add-ins works for all Windows accounts.
Install for all users

The Solution

Close Outlook and restart it using Run as Administrator then remove the add-in. Close Outlook and restart Outlook normally when finished.

To Run as Administrator, right-click on outlook.exe or the Outlook shortcut and choose Run as Administrator.

If Run as Administrator is not listed, hold Ctrl+Shift+Alt as you right-click on the shortcut to show the full menu.

This was just what I needed help on. Unfortunately didn't work. Windows 10 Pro with Outlook 2016. I started Outlook with Run as Administrator and still got the message about not being able to make changes. I'm totally lost here. Why would that not have worked?????

Can we search information in this website? I didn't find the search icon here. The articles here are really useful.

There is a search box in the left sidebar. On mobile devices (or narrow screens) it will be near the bottom of the page.

Thanks a lot,
the "hold Ctrl+Shift+Alt" did the trick for a similar, excel related, problem

If the above mentioned solution didn't work, you can click on "windows button" to open the start menu. And write "winword /safe" while on the menu. Then right click on "Microsoft Word - Run command" and click on "Run as administrator". The only difference is that you run Word in "Safe Mode".

running word in Safe mode won't help you if Outlook addins are the problem.
