I’m trying to disable some add-ins but I get the error;
"The connected state of Office Add-Ins registered in HKEY_LOCAL_MACHINE cannot be changed."
How can I disable the add-in without uninstalling it?
This error comes up when you try to disable an add-in which is registered at machine level rather than at user level. To disable the add-in, you must start Outlook with administrator privileges.
Windows Vista and Windows 7
Hold the SHIFT button and right click on the Outlook shortcut. From the menu choose “Run as administrator”. Then press Continue or provide administrator credentials when prompted. Once you’ve made the change, restart Outlook to run it under the user context again.
In Windows 8, it works the same as in Windows 7. However, when you right click on the Outlook shortcut in the Start Screen, the option “Run as administrator” will show up in a bar at the bottom of your screen.
In Windows 8.1, you can simply right click the Outlook icon in the Start Screen and choose “Run as administrator” from the menu that opens.
Logoff your user account and logon to the computer as an administrator. Once you’ve made the change, logon with your own user account again.
Note: See this Q&A for instructions on how to enable/disable add-ins.
Some add-ins can only be disabled when you
explicitly start Outlook as an Administrator.
