Problem: There is a known issue affecting Exchange 2007 web access from
outside the firewall. When you try to access
https://exchange01.fresnounified.org/exchange, you are presented with a logon screen as expected. However, once you sign in, your browser returns an HTTP 400 error page.
Resolution: None at the moment.
Workaround: Use terminal services (
Start -> run -> mstsc /v:termserv2.fresnounified.org or termserv5.fresnounified.org) and establish a desktop session. You will be able to access
https://exchange01.fresnounified.org/exchange from your remote desktop.
Who is affected: Only those people who currently have mailboxes on Exchange 2007 (about 39 people, almost all of them IT staff members.)
