Even if it is an IE problem you are more likely to find informed help about it from a newsgroup which knows about both products. Cross-posting to an Exchange NG (although I'm also wondering if perhaps Vista Security might also not be a better choice than just IE.) > I recently did a clean install of VISTA on an old laptop.

You could also try using Fiddler2 to elaborate on your symptoms but be aware that using it in an https session would cause its own problems with certificates (see the Fiddler FAQ page for details.) Also, in this situation I find it is often useful to turn the Fiddler proxy on to get into the https session; then turn it off to try to let IE recover from its interference. If you're lucky you will still be able to watch some of the rest of the https session even though IE thinks it isn't using a proxy any more. FWIW I recently used that technique on these Community web pages to discover a problem with Cookies which would have been much harder to notice without such a trace. > nor can I set up my Exchange Email in Outlook. > I can access all other OWA for our clients using HTTPS so that's not > the problem.

In addition to Fiddler2 I would try running ProcMon to get more clues about what exactly is going on. You certainly need a more detailed symptom description than just "I can no longer access OWA with IE7" in order to get any effective suggestions (unless somebody has already experienced a common issue, which as I indicated I would expect to be more likely to be known by Exchange specialists than by IE users.)
