2003 OWA

A couple of questions about OWA 2003.

1 - How to configure/install just OWA on a server that is not your Exchange Box.

2 - How to keep 2003 OWA from redirecting users to their home mail server? I have single organization with 2003 server and 5.5 server.  When the 5.5 users hit the 2003 OWA how do I keep OWA from trying to send them to the new server?  I just want to keep them on the new version of OWA.

Thanks
KAH

Hi KAH,

you have to install another Exchange Server as an Front End Server ( See Properties of the server object in System Manager). After that all request by OWA will be handled directly between the OWA-Users and the front end server.

The front end server Exchange 2003 doesn´t work with Ex 5.5 Back-End-Servers !!

You can install Exchange 5.5 OWA standalone directly on an IIS from 4.0 to 5.0. The connect from the OWA 5.5 Frontend to the 5.5-Backend is working over MAPI/RPC, while the OWA 2003 Frontend and 2003 BackEnd-Server talking over HTTP!!!

Got it.. so you cannot run Exchange 2003 OWA in an environmnet where users mailboxes are homed on 5.5.

So..

SRVA is 5.5
SRVB is 2003

SRVA does not have OWA on it.. it is hosted on another machine. How do you tell SRVB where to point the users for the OWA when they try to login?  Right now it is redirecting them to SRVA but since it does not have OWA it fails.

OK, i think the only working environment for you is:

- Install a Windows NT4.0 or Windows 2000 Server ( not IIS 6.0 !!! ) with Exchange 5.5 Outlook Web Access on it. Run Setup from the Ex 5.5-CD and select only OWA. Setup will ask you for a Exchange BackEnd Server, give the setup the 5.5-Server.

- OWA will work fine where ever the mailbox of the user ist ( 5.5 or 2003)

Only if all mailboxes migrated/moved to Exchange 2003 you can use an Exchange Server 2003 with OWA as Front-End-Server.

PS: The Mailboxes on 2003 can use OWA 2003 directly on the Mailboxserver !!!

I have owa running 5.5 now.. but the problem is it is hosted on a server not the Exchange 5.5 server..

So if a user comes in and logs into the OWA 2003 server and their mailbox is not on the 2003 server it redirects them to the 5.5 server.. but OWA is not on that box.. does this make sense?

Are you saying to use OWA 2003 you must have ALL mailboxes in your organization on 2003?  Or can you run them both together?

A. All Users use the OWA 5.5 Frontend-Server

B. Move all Mailboxes to Exchange 2003 to use OWA 2003

there´s no other chance ...

Even if you have some users on 2003 and some on 5.5?  I know right now 2003 OWA is trying to redirect to the 5.5 box.
