In a coexistence and project migration from Exchange 2010 to Exchange 2013, I cannot use the CAS 2013 to publish OWA services and proxy EX2010 mailboxes.
On CAS2010 there is a Symantec archiving solutions which OWA custom extensions doesn't work if the OWA2010 connections is received from CAS2013 in a proxy mode.
I'm looking a way to publish both 2010 and 2013 CAS server with 2 different external URL. Use the primary URL owa.company.com/owa to login on CAS2013 and in case the mailbox is on EX2010 a redirect legacy.compay.com/owa should be connect the user to the CAS2010.
Follow my scenario:
- Two Exchange 2013 Server (CU3) with CAS role
- Two Exchange 2013 Server (CU3) with Mailbox (in a DAG)
- Two Exchange 2010 CAS Servers SP3
- Two Exchange 2010 Mailbox Servers SP3 (in a DAG)
Actually any services (POP, IMAP, EWS, ActiveSync, Outlook Anywhere) are published by CAS2013 and are working fine with the proxy mode.
I configured different ExternalUrl and InternalUrl for CAS2010 and CAS2013, but when a mailbox user logon on CAS2013 it proxy the OWA page then a redirect.
Googling I understand is it possibile just configuring different ExternalUrl on CAS, but it's doesn't work to me.
thanks
