I have an Exchange 2003/2007 co-existance environment. Everything is working fine with the exception of OWA.
Those who still have a 2003 mailbox can connect to OWA as normal, but those on 2007 cannot. It simply says the page cannot be displayed.
ActiveSync works fine for 2003 users, but 2007 users receive error 0x85010014.
I have confirmed that OWA 2007 works fine directly, even over the Internet. SO it would appear that Exchange 2003 is not routing 2007 users correctly.
Where can I check what address the routing is sending 2007 users?
Nb: SSL certificates are confirmed as working
Exchange 2007 on Windows 2008 w/IIS7
Exchange 2003 on Windows 2003 w/IIS6
a 2007 cas can redirect to both 2k3 and 2k7 mailbox servers however an exchange 2003 frontend can only be used with exchange 2003 mailbox server
