Now available in Office 365, Admins can now check on which devices a user has installed Office apps. This is great news, this functionality was available in previous versions but was removed. Now that it is back I think many Admins will take advantage of it.

To see the Office installs for a user, login as an Admin to the Admin Portal. Go to Users and then Active Users. Select a user from the list.

When you select the user, in the right pane you now have the option to view and manage Office installs on devices. Selecting Edit bring up the next screen

You can deactivate a device, but note the user can easily reactivate the device for use.
