    Use the account that actually owns the Microsoft 365 subscription, then remove the account mismatch that is causing activation and Outlook problems.

    1. Check which account has the subscription. Sign in to Services & subscriptions at https://account.microsoft.com/services with all personal email addresses that might have been used. The Microsoft 365 subscription should appear under the correct account. If it does not appear, that email address is not the one tied to Microsoft 365.
    2. If there are multiple Microsoft accounts, identify the one to keep. A common cause is having more than one Microsoft account and signing in with the wrong one. The account used for Microsoft 365 is the one needed to install, activate, and manage Office.
    3. If the product was a home purchase and was never properly linked, associate it with the correct Microsoft account. Go to https://setup.office.com, sign in with the Microsoft account that should own the product, and complete the setup. The account is associated successfully when My Office Account appears with that Microsoft account email address and an install button.
    4. In Office, sign out of the wrong account and sign in with the correct one. Microsoft 365 apps do not support being signed in with multiple user accounts from the same Microsoft 365 organization or tenant at the same time. If the wrong account is signed in, switch accounts and use only the account that owns the license.
    5. If Office shows activation or subscription errors, run the Microsoft Support and Recovery Assistant. Run the Microsoft 365 activation troubleshooter on the same Windows PC where Microsoft 365 is installed. It must be Windows 10 or later.
    6. If activation still fails, check for multiple Office installs and remove the extra copy. In Windows 10 or Windows 11:
      • Open Control Panel
      • Select Programs > Programs and Features
      • Search for office
      • If more than one version appears, uninstall the version not being used
      • Restart the computer
      • Open an Office app and sign in again
    7. If the problem continues, reinstall Office. Microsoft recommends:
      • Deactivate the Office install
      • Use the easy fix tool to completely uninstall Office
      • Reinstall Office
    8. For Outlook-specific password or sign-in issues, reset or change the password for the Microsoft account being used, or update the password in Outlook if the account password changed.
    9. If the account email or password is no longer known, use the sign-in helper tool or the account recovery options.
    10. If self-service steps do not resolve it, contact Microsoft Support through Get Help and select Contact Support.
