Per "http://msdn.microsoft.com/en-us/library/aa155754(v=office.10).aspx" I can get the macro trusted by: "The easiest way to prevent the macros security warning from appearing is to change the Outlook macro security setting to Low." I have quite a few PC's that I would have to go around to do that to individually. Is there a way I can script this so I don't have to do it on each desktop individually/manually. The systems are mostly XP workstations logging into a domain. I don't really want to use certificates if I don't have to.
