Product update #KB5002907, deleting my Microsoft Office Product Key

I purchase Microsoft Office Professional Plus 2016 & Product Key thru my Military/DOD Home Use Program during my service in the US Army & DOD. Now, my WORD, PP, and Excel do not open, I been told it's because of a product update KB5002907...

Hi Tony Torres:

You might find some helpful suggestions in the 28-Sep-2026 Your Windows Guide article Office 2019 Deactivated After Windows Update: How to Fix Unlicensed Product Error. Information in that article applies to both MS Office 2016 and 2019.

As noted in that article, the problematic KB5002907 update should appear as “Click-to-Run Update Support” in your Windows Update history if it was installed by a recent Windows Update. From the Windows Update history on my Win 10 Pro v22H2 ESU laptop:

Once my damaged MS Office 2019 C2R product was automatically fixed by a repair reinstall I launched Word (any Office program like Excel, Outlook, etc. would have worked) and clicked the "Get Started" button to sync to my Microsoft Account and reactivate my MS Office 2019 license.

If you log in to your Microsoft Account at https://account.microsoft.com and go to Subscriptions is your MS Office 2016 Pro Plus product listed there? If so see the MS support article Download and install or reinstall Office 2021, Office 2019, or Office 2016 for instructions on how to reinstall and/or reactivate your MS Office product. From my own Microsoft Account:

IMPORTANT:

Just FYI, several years ago I legally purchased Microsoft Office Professional Plus 2010 at a deep discount under the Microsoft Home User Program (HUP – now called Microsoft Work Discount Program) through a previous employer, but I could not use the product key after I left their employment because the product key was registered under my work email address and that email address was inactivated after I moved to a new employer. I opened a case with Microsoft Support and gave them my order confirmation number but they were adamant that the product key was only valid as long I worked for the same employer who offered me the MS HUP discount.

I purchased a retail version of Microsoft Office Home and Business 2019 C2R from Best Buy (Canada) in 2019 and the Subscription tab of my Microsoft Account no longer displays a product key like it used to (see the last image above). If I want to reinstall MS Office 2019 my understanding is that I would use the Install button on that Subscription tab, and once Office is reinstalled all I would have to do is launch an Office program like Word, Excel, etc. while connected to the internet and the reinstalled Office suite should be automatically activated without having to enter a product key (assuming my product key was still “legitimate”).

Thanks. However, this is what I got as follows when I added what you indicate:

Hello Tony,

I understand the concern, especially since this was an Office Professional Plus 2016 purchase through the Microsoft Home Use Program (now called the Workplace Discount Program).

At this point, I would not conclude that KB5002907 permanently deleted or cancelled your Office license. There are recent Microsoft Q&A reports describing Office 2016/2019 activation problems after KB5002907, but those reports do not by themselves establish that the update invalidates legitimate perpetual licenses.

Office Professional Plus 2016 obtained through the Workplace Discount Program has a different activation/reinstallation process from a normal retail Office purchase. Microsoft states that customers who purchased Professional Plus through this program can retrieve the product key from the Workplace Discount Program Order History using the work email associated with the purchase.

I recommend checking this first:

Go to the Microsoft Workplace Discount Program Order History and sign in using the work email associated with the original purchase.

Check whether the Office Professional Plus 2016 order and product key are still available.

If the key is available, use the Workplace Discount Program installation procedure to reinstall/activate Office.

If the key is not available or is rejected, contact Microsoft Support with the original order information and proof of purchase.

Microsoft also provides OSPP.VBS /dstatus for Office 2016 to identify the last five characters of the product key currently installed on the computer:

cscript "C:\Program Files\Microsoft Office\Office16\OSPP.VBS" /dstatus

The command can help determine whether the Office installation still has a license/key registered locally.

One important point: Office 2016 reaching end of support does not by itself mean that an existing perpetual license becomes invalid. Microsoft continues to document installation and reinstallation procedures for Office 2016.

If the original Workplace Discount Program order and product key can no longer be retrieved, I would escalate that specifically as a Workplace Discount Program purchase/license recovery issue, rather than purchasing another Office license immediately.

Also, avoid posting the full product key publicly. If Microsoft Support requests it, provide it through the private support channel.
