Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello Michael Woolsey,
This may be related to optional update KB5002907, which caused some Office 2016 and Office 2019 installations to appear unlicensed or, in some cases, be removed.
Please try the following suggestions:
- First, review KB5002907: Optional update for out-of-date Microsoft 365 Apps installations. The recommended solution is to reactivate the purchased Office product or reinstall it if necessary.
- Open Word or Excel and select File > Account. Select Activate Product or Change Product Key, then sign in with the Microsoft account originally used to purchase Office 2019. If Office was activated with a product key, enter that key instead. For more details, see Activate Office for Windows.
- If Office 2019 is listed under Control Panel > Programs > Programs and Features, select it, choose Change, and run Online Repair.
- You can also sign in to the Microsoft account Services & subscriptions page with the account used to purchase Office. If Office 2019 is listed there, download and reinstall it.
Please let me know how it goes after trying these steps, and I'll be glad to continue looking into it with you.
