Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Common reasons for that message are:
- The username or email address entered is not recognized.
- The account has not been signed in to for more than two years and may have been deleted.
- The account being used is a work or school account, not a Microsoft personal account.
What to do:
- Verify the exact sign-in name being entered.
- If the message says “We couldn't find an account with that username” or “account doesn't exist”, use the Sign-in Helper tool.
- If the account is a work or school account, sign in through the My Account portal instead of the personal Microsoft account flow.
- If the account has been inactive for more than two years, it can no longer be reopened.
- If sign-in still fails, use Contact Microsoft Support. Support agents cannot send password reset links or change account details.
