Hi, from what I read on TechNet I understand that transport rules are stored in Active Directory. During the setup of Exchange 2013 transport rules are read from AD and imported in Exchange 2013. So I will have a copy of XCH2010 transport rules in XCH2013.
My question is: during coexistence are transport rules applied twice then? For example: I have a rule that processes all messages sent or received in my company and forwards a copy to a specific mailbox (it's a journaling basically). Do I have to expect that
if user A (on XCH2010 DB) sends an email to user B (on XCH2013 DB), I will have two emails in my journaling mailbox? In other words, is a transport rule application scope "organization wide" or "server wide"?
Thank you,
Francesco B.
