I am using office outlook 2003 & it has just stopped sending mail.
I can receive email no problem but when I try to send I receive the message as shown below (with recipient email address in the brackets)
Your message did not reach some or all of the intended recipients.
Subject: FW: Updates for your purchase from serengeti2 - 10-Oct-11
Sent: 13/10/2011 09:56
The following recipient(s) could not be reached:
(intended reciepient address) on 13/10/2011 09:56
554 Authentication Failed, must login
This message appears regardless of who I try to send mail to.
If anyone can help I would be very grateful as using webmail to send is a drag.
Just to let you know I have been doing some homework since posting the message above & found out that my email server is having some problems!
