subscription

Try these checks in order:

1. Confirm the daughter is still using the same Microsoft account that accepted the sharing invitation.
   • In Word or another Office app, go to File > Account.
   • If multiple accounts are signed in, sign out and sign back in with the account that accepted the family sharing invite.
2. Verify the shared subscription is visible on the daughter’s Microsoft account.
   • Sign in to Services & subscriptions with the invited account.
   • The shared Microsoft 365 Family benefit should appear there.
3. Check whether the daughter is in another family group.
   • Sharing only works if the invitee joins the subscription owner’s family group.
   • If already in another family group, that group must be left first, then the daughter must join the subscription owner’s family group.
4. Re-share the subscription.
   • On the subscription sharing page, use Stop sharing for the daughter, then share again.
   • If needed, use Invite to family so the daughter is in the correct Microsoft family group.
   • Important: when sharing is stopped, access to benefits ends, including extra OneDrive storage and Microsoft 365 desktop apps.
5. If Office still shows the subscription as expired on the device, reinstall Office from the invited account.
   • First uninstall existing Office apps to avoid conflicts.
   • Restart the PC.
   • Then sign in with the invited Microsoft account and install Microsoft 365 again from Services & subscriptions.
6. If the apps still show expired after that, contact Microsoft Support through Contact Support.
