How to setup up Exchange 2003 for external Outlook access

Hello all,

I just took admin responsibilities for a SBS2003 box. I have OWA and ActiveSync setup and flowing properly. My questions are: Can I setup a users Outlook 2007 to access Exchange externally using OWA or ActiveSync? If not, how would I go about setting up IMAP, POP, or HTTP to allow the external access? And can they co-exist? Thanks!

Info:
SBS 2003
Exchange 2003
SonicWall Firewall
Outlook 2007

I will look this over and post back once I have had a chance to try this out. We have self signed. Will enabling this cause issues with OWA, Remote Web Workspace, or ActiveSync?

The truth is I've never had to do anything other than run the Connect to the Internet and Email Connection Wizard in SBS and Outlook over HTTP just works

The first link should just be used as a confirmation of your settings...I wouldn't change anything without asking if ActiveSync and OWA and RWA are work

Outlook over http should be working as well.
