nbroad -> OWA with two Back End Exchange Servers (22.May2008 8:02:50 PM)
|
Hi,
I have successfully got ISA 2006 - Exchange 2003 OWA and ActiveSync up and running, sort of!
I have an SSL cert installed on the ISA Server and one of the Exchange Servers and it seems to work ok:
We have two Exchange 2003 servers, both backend, call them SERVER-A and SERVER-B.
The ISA publishing rule is configured to connect through to SERVER-A
ActiveSync from the internet over SSL works fine regardless of whether the users mailbox is stored on SERVER-A or SERVER-B.
OWA works fine for users with mailboxes on SERVER-A
OWA for users with mailboxes on SERVER-B fails. From what I can see, OWA redirects the browser to SERVER-B and that's why it fails.
I'm not experienced with Exchange Front End / Back End configurations so not quite sure where too from here.
I see a couple of options:
a) Implement a new Exchange 2003 server and make it a Front End, adjust the ISA publishing to point to this server. Will this work? I want to avoid this for cost reasons!
b) Enable SERVER-A as a Front End server. I've searched all over for an answer to this question: Can an Exchange 2003 Server be Front End plus still hold mailboxes. I read an MS article saying it 'shouldn't' hold mailboxes but haven't read anywhere that it actually can't??
Is there anything fancy in ISA2006 that I could do to fix the issue?
Regards,
Nigel
