Hi
I setup work email from home. Checked server requires authentication because
it does. Correct server names. Can receive email from server but cannot
send. Exact message I get
is below:

550 must be authenticated

These users exist on the server I am sending through; I send/reply from work
fine. Set up these users in new contact folder at home office. Only
difference is Office 2000 SR-1 at work. Any Ideas???

Please help
