Background: We have recently put in a new Windows 2008 Server, Exchange 2007 to replace a Exchange 2003 to Exchange 2003 Server. The schema been updated, the mailboxes moved across and sending and receiving mail.
We still run a ISA 2004 Server to act as the company's firewall.
The issue resides around OWA and the redirection of /exchange to /owa, I am not using SSL for owa and have removed these attributes from IIS 7, I can remotely access the website using http://mail.domain.com/owa but if I use http://mail.domain.com/exchange it redirect it to http://mail.domain.local/owa
which of course fails from an external IP.
So is the issue around ISA 2004 that 2007 believes it is an internal address and instead of using the external redirect it uses the internal domain, if so is there a work around so that it publishes the external domain.
I have completed the internal and external url fields to be correct, other then this issue owa seems to be operating fine.
Any help will be greatly appreciated
