How to remotely add new email account using Outlook with Exchange server?

We use Outlook 2010 connecting to Exchange 2010.
I'm currently outside of LAN and need to set up a new Outlook account connecting to our Exchange server. I can successfully ping our Exchange server name (server.domain.com) and it will resolve into a public IP address without a problem. But after entering the user name and click "Check Name", it says:

"The name cannot be resolved. The connection to Microsoft Exchange is unavailable."

Can you help please?

I've requested that this question be deleted for the following reason:

my question is confusing since it is for setting up a Outlook account, not creating a mail account in Exchange.

Thank you so much.
Only think I found critical is, connecting VPN first to set up the Outlook profile with the Outlook Anywhere ticked, and Proxy etc. After this initial setup, you will be able to access Outlook/Exchange service without VPN. Here is the details:
--------------
Best secret I found in doing this is either create profile and resolve name on the LAN first or via VPN. Set up Mail Profile from Control Panel -> Mail (32 bit). Create profile and follow wizard, except check box for manual setup and use INTERNAL Exchange Server name, and “Check Name”. (This is when you would need to connect VPN first, if you’re not on the physical LAN.) When name comes back underlined (successfully resolved), go to More Settings button, and proceed to the tab to set up Outlook Anywhere proxy server (remote.yourdomain.com, in the case of SBS 2011 default.) Leave the LAN or disconnect the VPN and launch Outlook. You should be prompted for a login (domain\username format) and password. If this is your first time connecting Outlook on this machine, it’ll ask for your name and initials, then “preparing mailbox for first use” and so on until you are looking at your mailbox, FROM the Internet, no VPN required. Everything else in the original article is rock solid helpful.
