When installing Microsoft Office or the Teams app on a Windows desktop you may be prompted to “Stay signed in to all your apps” and the default option is OK.
By clicking OK you will be registering your device against the Glow tenancy and this is not recommended.
Please choose “No, Sign in to this app only”.
This will prevent device registration. If you’ve registered a device and wish to remove the registration please see Resolving errors where device registration has happened – Error CAA50021
