Sounds like FBA isn't enabled on the 2003 server. It needs to be. Regards,

Question re this procedure. If using ISA between the 2 exchange servers and the big bad internet, and so FBA is disabled on the exchange servers can this work. FBA is enabled on the ISA server. It seems to almost work, If logging onto a 2003 account via the 2010 server owa url, I get prompted to login twice, and after entering the credentials the second time, I login fine. Both exchange servers are single server setups. Or is there a better way of doing this during the co-existence period? Thanks. Glen. From: Michael B.

A couple of excerpts from an article I had published earlier this year: Next, configure the Exchange 2003 OWA URL that Exchange 2010 will use to refer OWA clients whose mailboxes are hosted on the Exchange 2003 server, to that server. For this example, open an EMS session and enter: Set-OWAVirtualDirectory Clark2008\OWA* ` -Exchange2003URL "https://legacy.clarksupport.com" .... As mentioned earlier, Forms-Based Authentication (FBA) must be set on the Exchange 2003 server for OWA to allow for seamless transfers from the Exchange 2010 server. Using the Certificates MMC or the Exchange 2010 EMC, you should now export the SSL certificate that we created earlier in this article to a PFX file (ensuring that you export the private key!). Copy the PFX file to the Exchange 2003 server and import the key there, also using the Certificates MMC. Using the IIS Management Console, modify the properties of the Default Web Site to use the new SSL key. This will allow the "old" Exchange to accept both the legacy name (legacy.clarksupport.com in this example) and the current name (mail.clarksupport.com in this example) until DNS is updated. Once the update has happened, execute "iisreset" or reboot the old server to begin using the new certificate. .... Regards, Michael B.

This facility has a trust to an Exchange 2010 Resource forest. The URL for this facility points to their Exchange 2003 server to serve up the OWA requests. We are moving mailboxes from Exchange 2003 to Exchange 2010 and would like to keep the mail.company.com URL link the same for the users of this facility. However, I am trying to figure out the best way to keep this link working so that users can still go to one link, regardless of where there mailbox is located and be able to sign in. Once all users are moved over to the Exchange 2010 server, we are going to transition the link to point to the Exchange 2010 server, but until then, I would like to keep this link intact and not change anything during our transition. I am trying to find some articles about this situation, but not really coming up with anything that makes sense. Any input on this topic is appreciated.
