Our OWA doesn't work properly in Internet Explorer 8.
I can login normal, but if I click to open an email or make a new it prompts for username and password again. Now I have to login with "domain\username" - at the first login I don't need the domain.
At least I only have to do it once - it works afterward (until next time), but our users don't understand this and it didn't do this before.
I just checked on another pc that it still works with Internet Explorer 7.
We run Microsoft Exchange 2003.
