Attach Outlook 2010 to Exchange Server 2007

I have installed Exchange Server 2007.  I created my mailbox and successfully installed Outlook:Mac 2011.  My problem is that I cannot get Windows Outlook 2007/2010 to successfully attach to the Exchange server.  When adding the account everything is verified.  When I launch Windows Outlook 2007/2010 I receive the following error:

"cannot open your default email folders.  You must connect to Microsoft Exchange" with the current profile before you can synchronize your folders with your Outlook Data file (.ost)"

Sounds like your profile had already been created before you tried to connect to outlook. If there is no email data on the client to be saved, just delete the profile and create a new one for exchange.
Are you able to open the users mailbox using the Outlook WebApp/ OWA?

Is there a client firewall on either the desktop running Outlook or the server running Exchange?
Is there a firewall between the client and server?

For troubleshooting purposes, try disabling any firewalls on the Windows client/server, then configure the Outlook profile manually, ensuring the option "Use Cached Exchange Mode" is NOT checked. Also on the More Settings button, then Connection tab, ensure the "Connect to MIcrosoft Exchange using HTTP" option is unchecked.

I assume you're using a MAPI connection to Exchange, and not IMAP or POP3. Is this correct?

@gcoltharp - I tried that and I got the same error. @PacificMist - Firewall is not enforced.  I am removing the Office 2010 Professional and will re-install.
I've reinstalled the Outllook 2010 and the check names works correctly.  However when I begin the application I continue to get the same message as stated earlier.  
I would remove the profile then browse to the local settings and app data folders and delete all remnants to the old profile and then recreate.

It sounds like there is a bad or stale ost file in there that is getting reassociated with the new profile.
