I have an Exchange 2007 server setup for corporate email and I have configured OWA but I cannot access OWA unless I am on my local network. I have a SonicWall firewall and when I try to open up OWA from a PC that is not on the network by typing the URL (http://mail.companyname.com/owa
), I get my log in for the SonicWall. I want to be able to get a step by step process to make sure I have configured OWA correctly, to make sure the correct firewall ports are open, and then configure BIS for approx. 3 Blackberry users to access their email (they do not need to access public folders or calendars).
