We are adding a second Exchange server onto the domain with the hopes of retiring the first box when the configuration is complete, tested, and working. It was a fairly painless install with SERVER1 being the Master and SERVER2 being the Master. SERVER1 was set up with OWA and RCP over HTTP working without error. SERVER1 is running MSServer 2003 with Exchanger server 2003 Enterprise SP2. SERVER2 is running on MS Server 2003 R2 with Exchange Server Enterprise SP2.
https://SERVER2/exchange works internally using a self certified certificate (It was exported form SERVER1)
All my research says that I can use the single instance of OWA over SERVER1 but when I access OWA externally, https://external.domain.com/exchange, I can only log on and access users on SERVER1. (OWA is using Forms-based authentication) Trying to access users located on SERVER2 gives me "Internet Explorer cannot access web page"
If I change my firewall access rules on my Sonicwall Firewall to point to SERVER2 (not using forms-based authentication) and still using the same URL https://external.domain.com/exchange, I can then log in and see users on SERVER2 but not those users on SERVER1 however Outlook using RCP over HTTP doesn't work .
Now to get to my question, How can I configure OWA using https://external.domain.com/exchange to authenticate and access Mailboxes and get Outlook using RCP over HTTP to work with both servers?
