Thanks for reaching out. If Microsoft says there is no account, it usually means the account is deleted or inactive, or the email entered is not the exact same one used before. Go to the official recovery https://account.live.com/acsrand try to recover the account, then check https://account.microsoft.comif you pass verification.
If recovery fails, Microsoft states deleted accounts cannot be restored and you need to create a new account. When was the last time you successfully signed in and are you sure the email and domain are exactly correct?
