Need some help. My boss sent an e-mail to a recipient, and got the following bounceback message from System Administrator. We run Outlook 2007 on Microsoft Exchange 2003. Not experiencing any other bouncebacks currently
The following recipient(s) cannot be reached:
email@example.com on 4/1/2009 12:53 PM
There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.
<myserver.mydomain.priv #5.5.0 smtp;550 No such user (firstname.lastname@example.org)>
Can you help me out with this and what to look for? Is this on my side or on the recipients side. I would think it is the recipient's side. Thanks.
