Exchange Server 2007 SP1.I have to automatically add signature on my AD users exchange/outlook messages when they are sent.Reading on the web, it seems that it is not possible via standard administration tools but I should write some custom trasport agent or what else?I have developing skills so what is the right procedure to go ?Any help appreciated.Best regards.

Are you talking about disclaimer? If you add disclaimer through Transport rules then it is common for all users and transport rules can not add dynamic values in it (based on display name or first name, last name of individual user). Exchange 2007 - Transport Rules &Disclaimer How to Configure a Disclaimer So yes, if you want to add dynamic text into disclaimer (or signature) then you need to create custom transport agent based on your requirement with Exchange SDK.

Thanks Amit, examples are hard but I'll go into this.I followed this thread:http://forums.microsoft.com/technet/showpost.aspx?postid=2197094&siteid=17&sb=0&d=1&at=7&ft=11&tf=0&pageid=0but it isn't so clear how to modify Body message.Regards.

Yes, you may try by posting your query in Development forum since it involves requirement of programming skills TechNet Forums Exchange Server Development

Hello, I have created a transport rule following this steps: http://exchangeshare.wordpress.com/2008/05/17/exchange-2007-transport-rules-disclaimer/#comments I have seen in internet some webs that tell similar steps. My problem is that the Microsoft Outlook doesn't apply the transport rule. In that case is a disclaimer rule. I have waited 2 hours, but the disclaimer doesn't apply. We only have one Exchange server and one Active Directory. Someone knows what is happening¿? Thanks in advance.
