Does anyone know a registry setting that can be changed to enable cached exchange mode in outlook 2003?? What I need to do is check about 40 users pc's to make sure that they have this enabled, and if not I have to enable it. But this will take forever to do, considering I have to co-ordinate all of this with users, to do it when they have free time. So basically I am trying to see if I can do this somehow without them knowing and without any intervention from the user. I think I am hoping for a bit too much in this case, but who knows worth a try too see if anyone knows of a way to do this??
