I just set up Outlook 2003

The email account I set up tested ok with the test option in the program.
However, I am not able to send or receive emails.

When I hit send/receive, a window pops up and closes in a flash and nothing
happens.

Any idea what is causing this? Should I reinstall? I have reviewed all my
settings and can't figure out what is keeping the program from working
especially since the test worked.

Any ideas

Thanks

Bruce
