Fix Microsoft Office Repeatedly Asking for Sign-In on Windows 11
Question details
The user is experiencing repeated sign-in prompts and 'unlicensed product' errors in Office apps like Word and OneNote on a new Windows 11 PC, despite having an active Microsoft 365 subscription.
- Product
- Microsoft 365 (Office)
- Device & OS
- Windows 11
- Scenario
- Trying to edit documents in Word and OneNote on a newly setup computer.
- Observed behavior
- Office apps repeatedly ask for sign-in and a Windows PIN. Eventually, Word reports that the product is unlicensed and completely blocks document editing.
Manually save or back up any currently open or unsaved documents in Word and OneNote to a local folder or external drive to prevent data loss before proceeding with uninstallation.
Remove Conflicting Office Versions and Reinstall Microsoft 365
New Windows 11 PCs often include preinstalled Office apps that conflict with your paid Microsoft 365 subscription, triggering persistent sign-in loops and unlicensed errors.
When multiple versions of Microsoft Office exist on the same machine (such as a preinstalled version, an old Office 2013 license, or conflicting 32-bit and 64-bit files), the software struggles to verify the active license. Removing the conflicts and performing a clean installation of the correct version will resolve the recurring sign-in prompts.
Go to account.microsoft.com/services in your web browser and sign in using the Microsoft account associated with your active subscription to confirm its status.
Open Windows 11 Settings, navigate to 'Apps', then 'Installed apps'. Search for 'Office' and uninstall any older versions (like Office 2013) or preinstalled default Office packages.
After restarting your PC, log back into your Microsoft account dashboard online and download the 64-bit installer for Microsoft 365 to ensure a clean installation.

Frequently Asked Questions
Why does Word say 'unlicensed product' when I have a subscription?
This usually happens when multiple versions of Office are installed on the same PC, causing a license conflict, or if you are signed into the app with an account that isn't linked to your active Microsoft 365 subscription.
Can I keep Office 2013 and Microsoft 365 on the same Windows 11 PC?
It is strongly discouraged. Mixing different Office versions, especially a 32-bit older version with a 64-bit newer version, frequently causes activation conflicts, unresponsiveness, and repeated sign-in prompts.
How do I stop Office apps from constantly asking for my Windows PIN?
The PIN prompt is tied to Windows Security and account verification. Resolving the underlying Office license conflict by removing old versions and signing in once with the correct Microsoft account will generally stop the repeated PIN requests.
Will uninstalling Microsoft Office delete my Word documents?
No, uninstalling the Office application does not delete your personal files or documents stored on your local drive or in OneDrive. You can safely reinstall Office without losing your work.
