I am in the process of transitioning from Exch 2003 on Win 2003 Std. to Exch 2007 on Win 2008 Std.
The next step is OWA.
I can use OWA the same way as we always did for users who are not moved to Exch 2007, yet - https://webmail.company.com/exchange2003
I can usa OWA internally for users who are moved to Exch 2007 - https://exchange2007.corp.company.com/owa
However, I get an error if I try to log in to OWA from outside of the network - https://webmail.company.com/exchange2007
