Sending, receiving, and organizing email in Outlook.com
Hello, I’m Virginia.
How long is it since you signed in? If over 2 years then the account most likely has been deleted due to lack of use.
Check your browser’s password feature to see if the details were saved otherwise try recovering the account.
Try recovering your account here:
Can’t sign in:
You can try also https://support.microsoft.com/home/contact & type Account Recovery in the box, then choose the Contact Support tab above & select Windows, then recovery from the drop down menus.
If none of the above work then you’ll require the account recovery form:
Please note if you have 2/multi factor authentication active on your account then you cannot use the form to recover the account.
If you’re successful in changing the details then you may find that the account is limited for 30 days, this is a security feature & cannot be circumvented.
Please be aware that if the email address has been changed to that of the hacker &/or 2fa/mfa has been enabled then usually there’s nothing which can be done.
