I have seen some threads about exception in transport rules not working. I have Exchange 2010 and now migrating mailboxes to Exchange 2013. I have a rule running with exceptions but the same rule now does not work on the mailboxes I have migrated to Exc 2013. So I decided to create a similar rule in EAC but still the exception does not. Is this kind of bug or what. Actually what I have done is created a rule to append the Disclaimer in the emails sent, but when an internal user receives the email and replies, it should not append the email again, and this has and is working with my users still in Exchange 2010 mailboxes.
