What you’re seeing
- A banner reads "Unlicensed Product" or says Office couldn't verify your license.
- Editing is disabled and documents open in read-only, reduced functionality mode.
- The account page in Word or Excel lists a different email address from the one that holds the license.
- It began after a password change, a new laptop setup or a change to your subscription.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- The user's Microsoft 365 license was removed, swapped for a plan without desktop apps, or the subscription lapsed.
- Office is signed in with a personal Microsoft account or another work account that has no Office license.
- The user has reached the limit on how many devices can have Office activated at the same time.
- Leftover licensing from an older perpetual or volume-licensed Office edition conflicts with the subscription version.
- Proxy, firewall or web filtering rules stop Office from reaching Microsoft's licensing service for its periodic check.
- The local license cache is damaged or the system clock is wrong, making a valid license appear expired.
Why it matters
In reduced functionality mode staff can view documents but not edit or save them, which stalls contracts, spreadsheets and proposals mid-task. When the trigger is a billing or plan change, every user on that plan can be hit on the same morning. Some people work around it with personal accounts or free alternatives, scattering company files outside managed storage and creating data protection and compliance gaps.

Frequently asked questions
Will users lose the documents they were working on?
No. Files are not deleted; Office simply blocks editing until the license is verified. Anything already saved remains intact.
Do we need to buy more licenses?
Not necessarily. Many cases come from sign-in mix-ups or leftover old installs. If a license shortfall is the cause, we explain exactly how many you need and why.
