Login problem

If the sign-in name is not recognized, the supported checks are:

1. Verify the account type in Outlook or Office sign-in.
   • If the app detected the wrong account type, select Not Microsoft 365 or manually select the correct account type.
2. Confirm the sign-in name.
   • For Microsoft 365 business accounts, use the assigned user principal name (UPN). This may be different from the email address.
   • The sign-in name often looks like ******@company.com or ******@company.onmicrosoft.com.
3. Verify the password carefully.
   • If copying and pasting, make sure no extra spaces are included before or after the password.
4. Try signing in to the web portal.
   • If sign-in also fails there, the account may need action from the Microsoft 365 administrator.
5. Check whether the account is activated.
   • If this is a newly assigned Microsoft 365 account, first sign in to the Office 365 portal with the temporary password and create a new password.
6. If the account was blocked after too many attempts, wait 15 minutes and try again.
   • If the problem continues, the administrator may need to reset the password to unblock the account.
7. If the username is still not recognized, contact the Microsoft 365 administrator.
   • Outlook support agents cannot reset passwords or provide tenant-specific webmail settings.

The fact that the subscription is paid through 5/15/2027 does not by itself confirm that this specific sign-in name is the correct Microsoft 365 business user ID. The key check is whether the assigned UPN for the account matches the login name being entered.
