Managing personal Outlook.com account settings, security, and privacy
Hello,
I understand that you are having trouble signing in to your Outlook email account.
The “Account does not exist” error may appear if,
- The username may have been entered incorrectly. Please check it carefully for typing errors.
- The account may have been deleted due to inactivity.
- Someone may have gained unauthorized access to your Outlook account and removed the email alias.
So, could you please let me know when you were last able to sign in to your Microsoft account successfully?
If you haven't signed in with your Microsoft Account for more than 2 years, your account will be put into an inactive State and will be closed permanently. You cannot even use the Account recovery form to recover your account.
Knowing when you last successfully signed in to your account will help us determine the most appropriate solution for your situation.
