Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Dear Gerald Heuer,
Based on your description, it sounds like the Microsoft 365 apps on your laptop were originally activated using a Microsoft 365 subscription that has since expired.
To better understand the situation, could you please confirm the following:
- Under File > Account in Word or Excel, does the product show "Subscription Expired", "Unlicensed Product", or a different status?
- Does the account you're signing in with currently have an active Microsoft 365 license assigned?
If the apps were activated with an expired subscription, signing in with a different account will only work if that account has a valid Microsoft 365 license. In that case, there is typically no need to uninstall the Office apps. You can simply sign out of the old account and activate Office with a licensed account.
Try these steps first:
1/Sign out of all Office accounts:
2/Open any Office app.
- File > Account > Sign Out.
- Close all Office apps.
3/Open Windows Settings > Accounts > Access work or school.
- If you see your old work account connected, disconnect it (if appropriate and you no longer use it).
- Open an Office app again and sign in with the account that currently owns a valid license.
If no active license is available, the desktop apps may remain in reduced functionality mode, and you may need to renew/purchase a subscription or use the free Office web apps instead.
About the message "sign in with a different account as someone already using this account" this can happen if:
- The Windows profile is connected to a different Microsoft/work account.
- Office has cached old credentials.
- The same email exists as both a personal Microsoft account and a work/school account.
I hope information above meet your expectations, feel free to reach out if you have any other questions.
