Hello,

Any tips that really help.

Answer 1

Are you actually sending these messages? Are they in your sent items?
Sounds like you are being spoofed and seeing the backstatter NDRs?

If so there isnt much you can do and it doesnt mean you are compromised.

Hi @Ahmed Bagaber

I would recommend changing your password and enabling two-factor authentication.

Check if the e-mails stop sending after you enable this.

Hi @Ahmed Bagaber ,
You could check the sign-in logs in Azure Active Directory admin center . Check to see if any IP address from Japan have logged in to your account.
