Outlook not connecting with Exchange server

I am using Outlook 2007, Windows XP SP2.  I just installed Outlook 2007 on three computers.  One is giving me trouble.

I am using a hosted Exchange server provided by 123together.com.

Starting Outlook, this error message appears:

The connection to Microsoft Exchange is unavailable.  Outlook must be online or connected to complete this action.

I Click OK.

A dialog box appears asking for Exchange server name and name. I have tried using the user name and the user's email address.   When completed, I get this error message:

Cannot open your default email folders.  The file C:\Documents and Settings\Barry\Local Settings\Application DataMicrosoft\Outlook\outlook.ost is not an offline folder file.

I click OK.  Outlook closes.

I have installed Outlook 2007 on two other machines using exactly the same procedure and have not had this problem.  I went to one of these computers, set up a new profile and verified that the user name and user email are both correct and recognized by this Exchange server, so there must be a setting on the subject computer that is awry.  Ideas?
