Exchange online flagging emails with users who have the same name as someone internal as spam

Hello,

I have a question reagarding some thing I am observing which is interesting.

Occasionally a user with exactly the same name as an internal user will email someone in our company and it will be sent to the quarantine.

We know the reason is because of impersonation but we are trying to understand why it happens to only some people and not others.

For example, if I sent an email to myself from another domain where my display name is identical it passes correctly with a spam score of 1

But, if a user who is sending from somewhere like hotmail does the same test it can have a spam score of 5 and be sent to the quarantine and the details will be user impersonation.

Has anyone ever seen this, if yes, how would you fix it without turning the option off in Exchange Online to check for Phishing.

Thanks!
