I recently received a new HP Probook4520s pre-loaded with Windows 7 as a gift. I loaded my copy of Office 2007 on it and now I can receive email but cannot send email. The message says, "one or more parameters is incorrect." My settings are correct. I have double checked this with my ISP. Also, Windows update applied the Windows 7 compatibility update. I have read the other questions and don't see one that's exactly like this.
