SBS 2008 OWA not working directly

I have a very strange problem with owa on SBS 2008.  If the user accesses owa through remote web working it's fine, however if they go to https://<domain>/owa they are prompted for their username and password OK but after that they get a 400 error with https://<domain>/owa/auth/owaauth.dll in the browser title.  However if I try this as the administrator it works.  I am thinking permissions somewhere but where?  Anyone got the answer?

    Did this ever work?
    Did it stop after an update to the server? (Like Exchange 2007 SP2)?

    Accepted Solution

    This was a completely new build of SBS and all Service Packs were applied including Exchange SP3.

    I have now managed to get it working by disabling and then enabling (and re-entering the URL) for OWA within the Excahnge Management Console.  For anyone else with this problem it seems to be after a user has attempted to access the old OWA URL i.e https:\\<domain>\exchange.  I have also fixed this by adding a folder called exchange to C:\Program Files\Microsoft\Exchange Server\ClientAccess\ with the same permissions as the owa folder.  Then pointing the IIS exchange folder to this and adding a URL redirect to this redirecting to https:\\<domain>\owa and everything seems to work OK now.

    All I have to do now is install BES Express on it!!
