If you can get to the "more settings" area when creating a new mail account,
go to the security tab and uncheck the box at the top concerning data
encryption between Exchange and Outlook.

Other than that, this is a guess as I have never used Outlook 2007/2010
against anything less than Exchange 2003.

I am experiencing the same problem. I have just added a new desktop
(Windows
7 pro), with Office 2007, to a small LAN running on a W2K Server domain
and
Exchange 2000. I am getting the same message as stated below when I try to
add the exchange server to the Mail configuration tool in Control Panel. I
am
concerned that Windows 2007 may not be able to connect with Exchange 2000.

Any suggestions would be appreciated.

Thanks
John
