Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi 핼리 엘파이어,
Thanks for sharing your concern on Microsoft Q&A.
Based on your words, I understand that after transferring your Family plan to Personal, the Family plan still prompts on your Microsoft account, even the Office services show the right purchase.
In this case, you could try to refresh subscription and identity status.. such as following:
- Verify the active subscription on your Microsoft account to ensure the renewal and next‑charge date are correct. Go to account.microsoft.com/services and check the Subscriptions section (look for “Has recurring billing” or “Next charge”).
- Sign out of all Microsoft 365 apps and sign in again (Word, Excel, Outlook). This regenerates the license/identity tokens that Windows often reads for account notices. Close every Office app, sign out, reopen, then sign back in.
- Update Office to the latest build, then restart the PC. New builds include fixes that reconcile account prompts after plan changes.
- If you recently changed payment details or switched plans, confirm billing info is valid and saved; then restart Office apps and Windows. Identity prompts can persist until billing changes fully propagate.
Tip: After completing the steps, restart the PC and sign in again; banners in Settings > Accounts and the Start menu profile typically re-evaluate your account state after a fresh sign-in.
