Recently, our students have become unable to open emails from within Hotmail - however they can browse to their inboxes, but clicking on any email does not have any effect. Exactly the same as in this thread: (Edit, I can't post links due to my lack of posts, just search "Hotmail Group Policy")
But, clearing out IE's history doesn't cure it. I'm fairly convinced this is a group policy related issue as staff don't have this problem (they have a separate policy).
Can anyone help? Thanks!
