Please bear with me as I'm fairly inexperienced with Exchange. I've just installed Exchange 2007 on a new install of Longhorn Server Beta3. It seemed to install fairly clean. I've create a couple of mailboxes for two domain admin users and am able to email between the two locally. The problem is I'm unable to email to the internet, example - xxxxx@yahoo.com, or receive any email from the outside. Any suggestion would begreatly appreciate on where to start. Thanks in advance Steve

I was confused at first too. Exchange 2007 doesn't send or receive external email by default. you have toconfigure send and receive connectors. see http://technet.microsoft.com/en-us/library/bb125128.aspxfor more details, or go through the setup steps on the main ESM page
