Troubleshoot activation errors

If Microsoft 365 can't activate, it eventually becomes unlicensed and all editing features of Microsoft 365 are disabled. Microsoft can become unlicensed for a number of reasons. For example, if your Microsoft 365 subscription expires, you must renew your subscription to restore all features of Microsoft 365. 

If Microsoft 365 was pre-installed on your new PC, you must start an Microsoft 365 Family trial or buy Microsoft 365 to continue using Microsoft 365.

Note: If you're running Microsoft 365 on Windows 7 (which is no longer supported, see Windows 7 end of support and Office), you need to make sure that TLS 1.2 is enabled by default. See Update to enable TLS 1.1 and TLS 1.2 as default secure protocols in WinHTTP in Windows.
