Trying to login and update license

Try this in order:

1. In Word, Excel, or PowerPoint, go to File > Account > Update License.
   • This forces Microsoft 365 to refresh the license immediately.
   • The button appears in Microsoft 365 apps starting with version 2401, and its presence does not mean the license is expired.
2. Make sure the app is signed in with the correct account.
   • A Couldn't update license error is commonly caused by being signed in with an account that does not have the license.
   • In the top-right corner of the app, verify the signed-in account matches the one that owns the Microsoft 365 subscription.
3. Close all Office apps and open them again.
   • A successful license update may require restarting the apps so they can use the current license.
4. Check whether the product shows as licensed.
   • In File > Account, under Product Information, confirm the licensed product name is shown.
5. If the apps show Unlicensed Product, try these basic activation checks:
   • Sign in with the account used to buy or receive Office.
   • Check for multiple copies of Office installed, because multiple installs can cause activation conflicts.
   • Check whether the subscription is active.
6. Update Office.
   • Open an Office app.
   • Go to File > Account.
   • Select Update Options > Update Now.
   • If Update Now is missing, select Enable Updates first, then Update Now.
7. If activation still fails, check common Windows causes:
   • Verify the computer’s date, time, and time zone are correct.
   • Try running the Office app as administrator.
   • Check whether a firewall, antivirus, or proxy is blocking activation.

If the issue started right after a new purchase or new entitlement, background license refresh can take up to 72 hours, and Update License is the manual way to refresh it sooner.
