I only ever worked with Exchange 2010 which is great .. When I send an email to a person's work address, I have to add the word "PERSONAL" into the subject.
This is working fine on my private Exchange server using transport rules (2010) but not so much from my work Exchange which is 2003

Is there any way to do the same, so when an email is send to
@something.blurp that it will add the word PERSONAL to the subject automatically ?
