I have windows vista home premium using outlook 2003 and use two pop
accounts. I recently had outlook crashing and freezing. Microsoft helped me
create a new user and delete the old outlook account.
After setting up my e-mail accounts one account works fine but the second
account successfully completes the "test account settings" the test message
is sent and received. But when I try to use the account I can't send
messages. I get an instant reply undeliverable:  System administrator
Your message did not reach some or all of the intended recipients.  The
following recipient(s) could not be reached: I get this message no matter who
I send the message to.
This account does receive messages.
the next problem may be better addressed in another question but.
I am also not able to access the music, pictures or video files while
attempting to attach a file to a message.
