Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello, thank you for reaching out to Microsoft Q&A.
May I please know if you have a work or school account linked to your device or to OneDrive?
Go to Start > Settings > Accounts > Access work or school.
If you see a work or school account added there, please unlink that account.
Next, if you have added your work or school account in the OneDrive desktop app, right-click the OneDrive Work or School icon on the taskbar, then select Settings > Account > Unlink this PC.
Once that is done, sign out of all Office applications and then sign back in.
If you are still experiencing issues, try activating Office from a new local (administrator) profile:
- Press Windows + R, type netplwiz, and click OK.
- Select Add > Sign in without a Microsoft account (not recommended) > Local account.
- Create a username and password.
- Select the new user you just created, click Properties, and on the Group Membership tab, select Administrator.
- Sign out and sign in with the new local user profile.
Finally, open the Office apps and sign in with your personal Microsoft account.
Let me know if it worked.
