When opening Microsoft Outlook 2019 or any other apps in Microsoft Office 2019 Suite I receive a pop-up stating that "This version of Outlook (or any other app) isn't included with Microsoft Office". It then states "To use Outlook without interruption, you'll to buy a Microsoft 365 subscription." After closing that pop-up another one pops up informing me that I have 5 more days to create and edit documentation.

My Microsoft Office 2019 suite has been activated for years. Why is this occurring?

    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    • First, review KB5002907: Optional update for out-of-date Microsoft 365 Apps installations.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.
