Hi, I would like to know if there is a way to change the current undeliverable response when an email is sent to an unknown recipients within an Office 365 domain.
the current response seems to be too technical for layman to read and understand. I'm hoping to change it something like.
"Sorry, the email address you're sending to does not exist. Please call the office at "999". Thank you!
Is it possible to be changed at all?
tHanks!
