We have a brand new SERVER install with Win 2008 R2 w/ Exchange 2010. The OS is activated, the Exchange is in trial mode right now. I can add users just fine in Active Directory and then subsequently add them to Exchange to create mailboxes successfully. Here is where I run into a roadblock.
The first 35 or so created work great. Now when I add additional, I can still authenticate with Outlook clients and even use mail2web.com to login to mailbox. However when I try to send an e-mail to it I get the ERROR below. The first 35 or so WORK fine still. So what has changed to cause this issue? Things I have tried I list below.

1. I have rebooted server
2. I have deleted troublesome mailbox and added it back
3. I created a simple test@ account and it gives me same bounce message
