Have you tried creating a new mail profile via the mail applet in the
control panel? (don't copy the existing one. create new and try it before
deleting the old one.)

Hello. When I try to configure my Outlook 2007 client(RTM-version) I get
the
following error message: "The connection to Microsoft exchange is
unavailable. Outlook must either be online or connected to complete this
action"

I am constantly being prompted to login to the Exchange server even if I
have already logged in to our LAN. I use the same password and account as
when I log in to the domain, but Exchange will not accept it.

The description of the problem in kb927481 do not apply because we do not
run Exchange 2007 and I do not have the registry setting described in that
article.

I am running Windows XP SP2 with all the released patches after that. My
machine have runned Office 2003 before and I tried to upgrade first.

Any ideas?
Kind regards
Thomas
