Shannon,
There are lots of reasons for your problem. Are your accounts set up
correctly. Do they match the ISP's server addresses?
Let us know what you have tried during the "two days" that you reference.

I recently installed Outlook 2007 and everything works/tests just fine. The
major problem I'm having is that I cannot send a NEW message. I get an
error
that says "cannot send this item". I have looked for two days for a fix.
Can
anyone help?
