I have installed an ISA server with Exchange 5.5 behind it. That is working fine. Recently, I attempted to set up some exception rules in ISA to stop exe and vbs attachments from going directly to the user. I asked ISA to “Hold” the mail. This is still not working for me. What is new is that Outlook gives me a notification on my email enclosed in a yellow box that says “Outlook has blocked certain attachments that could be potentially unsafe” Why is it generating this message and where isthat being directed from?
