The e-mail account does not exist at the organization this message was sent to

I have a user set up with an external email address.  When I try and email the user I get "The e-mail account does not exist at the organization this message was sent to"
I was able to send an email to the same user with Gmail.  Even when I type the address in instead of choosing from the global contacts I get the error.  
We also have other users in our system with the same type of email addresses and they work fine.
I know the address is good.
Why would this happen to just one user?

The message means what it says. The server the message was delivered to doesn't recognise the account.
What it does not mean is that the message was delivered correctly.
Have you got message tracking enabled? If so that will show you what Exchange is doing with the message.

OK, I tracked the message and it looks like it's not getting out of our domain.

SMTP Store Driver: Message Submitted from store
SMTP: message submitted to advanced queing
SMTP: start message submission to advanced queue
SMTP: Message submitted to categorizer
SMTP: Message categorized and queued for routing
SMTP: Non-Delivery Report (NDR) Generated

This is a user in our domain with an external email address.  We have other poeple that have the same parameters that this does not happen to.

What exactly do you mean by a user in your domain with an external address?
Do you mean you are forwarding the email out to another email address? Ie the email address is not a domain that is under your control?

OK, so I think I found the problem.  When the user was created in the domain we put an external email address for the user.  Somehow when you look at the Global Address Book, it shows the correct email address in the email feild but when you go to the Email Address tab it shows 2 SMTP addresses.  One is the correct external address, the other shows an internal email address.  The internal address is not a real mailbox in our system.  This would explain the tracking not getting past the routing internally.

Which address is the default?
This user has a full user account? Does the user also have a mailbox? If so, that could be the source of the problem. You should have chosen the option to establish an external email address rather than a full mailbox.

I ended up deleted the user and waiting until the changes replicated to the address book.  Then I set up the user again using the same setting you recommended. Thanks for the help anyway.
