Using Win 7 32 bit with MS Office 2007. Outlook configured properly and sends and receives on test setting but when I try sending a regular email it just stays in the out box. Nothing happens. Checked with ISP, Comcast, for correct outgoing server. Test message works with 25 and 587. Anti-virus has been turned off for all mail. Still not working. Mail in outbox can be deleted but any new outgoing mail still sits in box. No error message.
