Microsoft 365 Unlicensed Product Banner: Fixing Activation Errors

Word opens with a red bar reading Unlicensed Product, or the user is told most features are turned off. Sometimes a sign-in prompt loops, sometimes it just fails silently. The apps are installed fine. The problem is that the machine cannot prove to Microsoft that this user owns a licence.

Activation depends on three things lining up: a licence assigned to the user in the Microsoft 365 admin center, a working sign-in to that account on the PC, and a clean activation state in Office itself. Check them in that order and you will find the break.

Check the licence in the admin center

Start where the truth lives. Go to admin.microsoft.com, open Users > Active users, select the user and open the Licenses and apps tab. The user needs a licence that includes the desktop apps, such as Microsoft 365 Business Standard, Business Premium, or an E3 or E5 plan. Business Basic and F3 do not include the desktop apps, and users on those plans will see Unlicensed Product no matter what you do on the PC.

Also confirm the licence was not removed and re-added recently, and that the tenant has no unpaid subscription. A subscription in a grace period will keep working for a while and then stop for everyone at once.

• Licence assigned and includes Microsoft 365 Apps for business or enterprise.
• Account is not blocked from sign-in and the password has not been reset without telling the user.
• The user is signed in to Office with the work account, not a personal Microsoft account with the same email address.
• Subscription status under Billing > Your products is Active, not Expired or Disabled.

Fix the sign-in state on the PC

The most common cause after a correct licence is a stale identity token. The user changed their password, or the device was joined to Entra ID after Office was installed, and the cached token no longer matches. Office keeps trying with the old token and fails.

Sign the user out of Office fully, clear the cached identities and sign back in. Do this before touching the activation state, because a fresh sign-in fixes most cases on its own.

1. In Word, go to File > Account and click Sign out under User Information. Close every Office app, including Outlook and Teams.
2. Open Settings > Accounts > Access work or school and confirm the work account is listed. If the device is supposed to be Entra joined and it is not, that is a separate ticket.
3. Open Credential Manager, Windows Credentials, and remove entries beginning with MicrosoftOffice16_ and ADAL.
4. Reopen Word, go to File > Account and sign in with the work account. Wait a minute and check the licence line.
5. If the prompt loops, run `dsregcmd /status` and check that AzureAdJoined or AzureAdPrt shows YES. A missing Primary Refresh Token causes repeated prompts.

dsregcmd /status

Reset Office activation state

If sign-in is clean and the banner stays, Office's own activation records are stale. Microsoft ships a script with Office that lists and removes installed product keys. Run it from the Office folder, remove every key it shows, then sign in again so Office fetches a fresh licence for the current user.

Check the Software Protection Platform service too. If it is disabled by a tuning script, activation cannot complete and the error is usually a generic "we are unable to connect right now".

1. Open an elevated command prompt and change to `C:\Program Files\Microsoft Office\Office16` (or Program Files (x86) for 32-bit).
2. Run `cscript ospp.vbs /dstatus` and note each Last 5 characters of installed product key.
3. Remove each with `cscript ospp.vbs /unpkey:XXXXX`.
4. Confirm the service: `Get-Service sppsvc` should be Running with a Manual or Automatic startup type.
5. Relaunch Word and sign in. The licence line should update to Subscription Product within a few minutes.
6. If the machine has a leftover volume-licence or Home and Student install alongside Microsoft 365, uninstall the extra one. Two Office installs fight over activation.

cd "C:\Program Files\Microsoft Office\Office16"
cscript ospp.vbs /dstatus
cscript ospp.vbs /unpkey:XXXXX
Get-Service sppsvc

Shared computers and device limits

Each Microsoft 365 user can activate Office on five PCs or Macs, five tablets and five phones. On a shared front-desk or shop-floor PC, a dozen users signing in over a month burns through activations and someone eventually sees Unlicensed Product on their own laptop.

For shared machines, enable Shared Computer Activation. Deploy Office with the Office Deployment Tool and set SharedComputerLicensing to 1 in the configuration XML, or push it through Intune's Microsoft 365 Apps policy. Users can also clear their own activations at portal.office.com under My account > Office apps, which is faster than waiting for support.

Takeaway

Unlicensed Product is a chain of three checks: licence assigned, user signed in, activation state clean. Confirm the licence in the admin center, fix the sign-in with a full sign-out and credential cleanup, then reset activation with ospp.vbs if it still fails. For shared PCs, turn on Shared Computer Activation so device limits stop biting.
