Q: Error 554 5.5.1. y sent messages are stopped by System Administrator

Original Title: Error  554 5.5.1. Advise please.
I have been using Outlook 2003/XP Professional since a few years now and had no problem in receiving/sending my messages. Recently I installed a new PC with WIN7/Prof. and reinstalled the Office 2003. I receive my messages. But my sent messages are stopped by System Administrator though I am a sigleuser/owner. I get the Error  554 5.5.1. Advise please.

Answer

A:

The 554 5.5.1 error is the SMTP error "no valid recipients".  It can occur if you've misspelled the recipient addresses but it can also occur if you are not properly authenticating to the outgoing server.
