Hello,
Are these emails found in your spam/junk folder?
Email spoofing happens when someone uses an outside mail server to send messages that pretend to come from your email address by forging the "From" field. They do not have access to your actual email account. To prevent and detect this, email providers like Microsoft use protections like SPF (to define which servers are allowed to send on your behalf), DKIM (to attach a digital signature to prove the email is real), and DMARC (to tell other servers what to do if a message fails these checks). If a spoofed email fails these checks, it will usually be flagged as spam or rejected.
So, if the email is already in spam/junk folder, you have nothing to worry about.
