Sending, receiving, and organizing email in Outlook.com
Hey there! Nice to meet you!
If I may ask, have you forgotten your account's password by any chance?
If not, may I know the exact error message upon signing in?
Do you still have access to your account's security information, email, or phone number?
Do you see any unfamiliar email addresses/phone numbers upon signing in to your account?
Did you have two-factor authentication (2FA) active on the account? If yes, do you have access to the 25-character recovery codes?
Lastly, may I know when was the last time you successfully signed in to your Microsoft account?
Best regards,
Darhyl
