Troubleshoot activation failures

If Office fails to activate, you can continue using Office for awhile, but eventually Office enters reduced functionality mode. Most buttons and features are disabled (greyed out), and (Unlicensed Product) appears in the title bar. If this happens, see Unlicensed Product errors in Office for help with troubleshooting common activation failures.
