Tore is right you cannot recall emails, but i have seen people send out a following email saying that th elast email should be ignored. Also in office 2007 with exchange 2007 you can set a time limit on the email and it will expire after that.

>We have a situation where we have generated automatic emails, within our process to a variety of users dependent upon a recipient list generated within the system.
>Once ONE of these emails has been responded to, we want to "RECALL" all the other emails. We can detect a reply from a user into the system, and we have the original list of recipients available.
>I am however clueless as to how, or even if, we can recall the other emails programatically.
