I have successfully tethered my laptop with my 8320 TMobile Curve, however I cannot send email via outlook, instead I get a send recieve error. Any ideas on what I can do to get this to work?

you shouldn't have to anything with Outlook. I believe a tether is a tether, as long as you have the setting to connect to the web you should have unrestricted access to send and receive email via Outlook...I know I do.
