I sent a message and got the following error from within our network. It should have never left my network, yet if you read the error info, the message is being rejected by an external domain. I am baffled! We are running Echange 2007 on a Windows 2003 server. For the most part all clients are using Outlook 2007, a few may have 2003. The domain is a 2003 domain.

I have gone through the settings in active directory for this persons account, as well as on exchange. I have looked at her desktop settings in Outlook 2007, all with no noticable oddities. She also uses an iPhone to access her email. I see no problems with it as well.

I am not the only one to get these errors sending email to her, i was investigating the problem for another user when I noticed it happend to me as well. This is a random error, some emails go through and some don't. As far as I know, it is only emails to her, i have no other complaints.

I am going to delete her exchange account and recreate it within the next few days, but wanted to see if there was a logical explanation from anyone first.

Following is the error----------------------------------------------------
