Mail Delivery has failed!

[susan]

Dear all,

Please help me with my e-mail account. I have Microsoft Exchnage POP3
5.0 on Microsoft Windows Server 2003 Enterprise Edition SP1. And I use
Microsoft Outlook 2007.

When I send e-mail to user (other domain) it delivery back as message
show below:

Delivery has failed to these recipients or distribution lists:

(e-mail address removed)
An error occurred while trying to deliver this message to this
recipient e-mail address. Microsoft Exchange will not try to redeliver
this message for you. Please try resending this message, or provide
the following diagnostic text to your system administrator.

To be sure, this user address is really correct. It's strange if I use
other account (yahoo or gmail)to send this e-mail and it works.

Anyone, can you help to give me any ideas about this? It's urgent for
me.

I look forward to hearing from you.

Thanks in advance,


Susan

Ok, there's no such thing as 'Microsoft Exchange POP3 5.0'. What version
of Microsoft Exchange Server is it?

When I send e-mail to user (other domain) it delivery back as message
show below:

Do all users have a problem or just one?
Does mail between users on the server work?
Are you able to mail *any* external domain?
Are you able to send mail via OWA? If you can't, then you need to look at
one of the Exchange newsgroups, like microsoft.public.exchange.admin, as
it isn't an Outlook issue. Be sure to tell them exactly what version of
Exchange you are running.

Anyone, can you help to give me any ideas about this? It's urgent for
me.

Honestly, if it is an urgent issue, you should contact technical support
using the phone numbers for your region.
