Trying to find a way for my users to have their cache autocleared on logout.. I know this is probably really really simple, I just can't seem to find a way to do it. Any help would be greatly appreciated.

With logout I assume you mean logout from OWA When using OWA, Exchange instruct browsers not to cache any pages.

If it isn't OWA you are talking about, this may help: http://www.microsoft.com/technet/scriptcenter/resources/qanda/nov04/hey1102.mspx
