I manage about eight users in an environment whose email is governed by an Exchange 2010 server (SBS 2011). The users have various devices (phones, computers, etc.) that are not managed by the domain.
We've been trying to come up with a better way to manage the email signatures for one subset of the user-base. In short: We went them all to be the same with the exceptions of name, title, phone, etc.
Right now, I am using a Transport Rule that drops an AD-customized signature into the messages. It works, but the users are squawking over my exception that prohibits applying the signature if the subject line contains "RE:". Admittedly, it's an inelegant way to prevent every outbound message from getting it's signature applied with each new reply.
I'm looking for something better and I hope someone here has a better idea.
