When using Outlook I get "Your message failed" 554 Tranaction

[Jerry]

When I try to send certain e-mails (not all) I receive the message "Your
message did not reach the intended recipient" " 554 Transaction failed" This
message pops=up immediately. Please help.

Are you sending via the same SMTP server as the ISP you are using? That
type of message usually indicates you are trying to relay through another
ISP SMTP server.
