KB5002907 is nuking valid licenses for Office 2016 and 2019 products

M C 30

Help, KB5002907 is removing the active valid licenses for Office 2016 and 2019 products. I have a valid license for Office 2016 PRO (Lifetime License) and it was removed by the Office 365 update. When will Microsoft pull the update and correct the issue?

We are experiencing the same issue on multiple PCs with legitimate perpetual Office Home & Business 2016 and 2019 licenses.

After KB5002907 is installed through Windows Update, the existing Office installation appears to lose or alter its activation/licensing status.

According to Microsoft's KB5002907 documentation, this update is intended for out-of-date Microsoft 365 Apps installations, while the affected PCs in our case have perpetual Office 2016/2019 installations.

Can Microsoft please confirm whether KB5002907 is being incorrectly offered to perpetual Office installations and whether this is currently being investigated?

We can provide Office builds, Windows builds, licensing status and OSPP.VBS /dstatus output from affected machines if required.

@Peter Beauchamp

Reinstall Office (if necessary) and reactivate your license. See the Important notice in the updated article at https://support.microsoft.com/en-us/servicing/os/microsoft-365/kb5002907-optional-update-for-out-of-date-microsoft-365-apps-installations . I have posted a similar reply elsewhere in the thread with a screen shot. Good luck.

Is there a class action lawsuit about this?

I got Office 2019 when I bought my computer from an electronics store locally. It has worked fine for years until this update. It is frozen asking for the pass key. I called the shop I bought my computer from and they are out of business and never provided me with the key.

I have tried everything posted by Ai and nothing works. It now shows my product as UNLICENCED. It wont even work when my computer is off-line. This feels criminal on the part of Microsoft. I even spent hours with a Microsoft technician and gave him access to my computer. He eventually just disconnected me from the conversation telling me I was SOL.

From my research it is this (Click-to-Run installs are designed to "phone home" every ~30 days to re-verify the license) that appears to be the technical trick that they use to not really sell you an Office program that will last the lifetime of your computer. It is criminal in my mind that they are allowed to disable a program like this.

Greg Billingsly,

If the cause of trouble is the Microsoft update discussed in this thread, all you have to do is reactivate your installation using your associated Microsoft account.

I still have no access to MS Office 2016 PRO (Lifetime License), and I have until tomorrow 29 SEPT 26, to input key, which I cannot find. Also, the Microsoft shares fix as KB5002907 accidentally breaks licenses, deletes Windows Office apps wasn't added to my system as an update.

If your system never installed the faulty update, the license problem you experienced may have a different cause. I recommend that you start your own thread. Use the Ask a question option. If you already started your own thread, please post follow-ups there. Good luck.
