Hello,
I have an issue with a fresh installation of Exchange 2013 SP1.
The are two AD site in different cities, connected by WAN link (site-to site VPN organized by Cisco ASA).
I installed two Exchange servers in Site A (MBX1 and MBX2, both with MBX+CAS roles), and one Exchange server MBX3 in Site B (also both with MBX+CAS roles).
Each Exchange hosts its own mailbox database (DB1, DB2, DB3 respectively), there are no DAG.
Users spread over all databases. For example, user1 has mailbox in DB1, user2 - in DB2, user3 in DB3.
When user1 opens OWA/ECP on CAS server MBX1 or MBX2, he successfully get into his mailbox.
But, if user1 opens OWA/ECP on CAS server MBX3, he get blank page (no error at all).
And vise versa:
When user3 opens OWA/ECP on CAS server MBX3, he successfully get into his mailbox.
But, if user3 opens OWA/ECP on CAS server MBX1 or MBX2, he get blank page (no error at all).
I know, that Exchange 2013 is able to proxy request cross site.
Where are no custom redirects set on IIS.
Also I check IIS (Back End Site) for right certificate.
There are no error in Windows Event log and IIS event Log.
All ports are allowed between sites.
Everything looks good.
What I did wrong? May be I need to enable cross-site OWA proxy in Exchange somewhere?
Or it is a CISCO ASA misconfiguration?
Any help would be appreciated!
Thank You!
