Hello. I just reformatted my laptop and installed Windows Vista Ultimate
Beta 2 and Office 2007 Beta 2. I am trying to configure Outlook 2007 to
connect to my Exchange 2003 Enterprise Server mailbox, but whenever I put in
my credentials it either asks for them again, or tells me the Exchange server
is unavailable.

I tried going through the control panel to create a different profile, but I
get the same thing. I unchecked cached Exchange Mode, tried first, last and
different usernames, and went in to Advanced Settings to change encryption
and authentication.

I know I am working with two beta products, but this is a pretty basic
function, and our Exchange 2003 server is pretty stable. I have another user
trying out Office 2007 and can connect just fine, but she just did an upgrade
of her Office 2003 installation on a Windows XP laptop.

Any suggestions would be greatly appreciated.
Thanks,
John
