Vista - Error when sending group mailing

When I am sending out an e-mail to quite a few people with a short message, I receive the following error message:

550 #5.1.0 Address rejected.

Any suggestions would be appreciated. I am using I.E. v.8

Thanks in advance for your response and support

IE8 has nothing to do with it.
In Windows Mail, right-click on your error message, copy, then paste it
into a reply here.
We can't do much troubleshooting without the complete error message.
How many recipients are you sending to at one time?

If you really mean "Outlook" you are in the wrong newsgroup.
The newsgroup to which you posted is for the Windows Mail program.
You are more likely to find Outlook experts in the Outlook newsgroup:

microsoft.public.outlook.general (via NNTP); or via the web:

http://www.microsoft.com/communities...utlook.general

It sounds like the email address you have for that one recipient is
no longer valid. Outlook's error messages are unnecessarily vague,
which is one reason why I gave up using Outlook.
