Add-In States for Microsoft Outlook

The following table describes the states that apply to an add-in.

State	How the State Changes	Impact
Active	Admin uploaded the add-in and assigned it to users or groups.	Users and groups assigned to the add-in see it in the relevant clients.
Turned off	Admin turned off the add-in.	Users and groups assigned to the add-in no longer have access to it. If the add-in state is changed to Active, the users and groups will have access to it again.
Deleted	Admin deleted the add-in.	Users and groups assigned the add-in no longer have access to it.

Consider deleting an add-in if no one is using it anymore. Turning off an add-in may make sense if an add-in is used only during specific times of the year.
