Office Portal:
-
Go to the Office Account page:
- Visit https://portal.office.com/account and log in with your Microsoft 365 (Office 365) account.
-
Navigate to "My Account":
- Under "Apps & devices" Tab on the left side
- You should see the devices menu and open it
-
View and Manage Installations:
- This will show you a list of devices where you've installed Office apps like Word and Excel using your account.
- You can also deactivate an installation from here by selecting "Sign out" or "Deactivate" next to a device.
If you still can't find it in either the Services & subscriptions page or the Office portal, your Microsoft 365 admin (if you're on a business plan) may need to provide access or check this information for you.
