Error - Rejected as sender

B

Billc1022

Hi all,
I'm using Outllook 2000 SP3. When trying to send my e-mail, I get an error
message:
"The message could not be sent, it rejected you as the sender. Server
Response: '550 5.7.1 Authentication Required'. (Account:
'incoming.verizon.net', SMTP Server: 'outgoing.verizon.net', Error Number:
0x800ccc78)"
Can anyone help?
Thanks,
Bill
