Hi, we have an exchange 2007 server, I have just setup a new laptop,
and all works ok until I try to connect remotely to my mailbox. Upon
opening outlook I am prompted for username, but each time the username
defaults to my windows username instead of domainname\username that I
need to enter.
I have tried saving this logon info for my user account in control
panel user accounts advanced etc but as every time I open outlook
when off my LAN the username shows incorrect and I have to type out
the whole domainname\username and it logs in fine. My previous laptop
always defaulted to domainname\username.

Anyone have any ideas?

I have tried NTLM and basic authentication on the outlook settings but
no luck, other users on our server dont have the same problem, I am
using Windows XP SP3 and Outlook 2007 SP1
