In order for Site1 to proxy EWS to Site2, you must remove the ExternalUrls from the EWS sites in Site2.

So there were/are 8 2010 servers in all just sitting there - 2 CAS/HT servers for each site, and 2 mailbox servers for each site). Fast forward a couple of years (yes, years), and we're looking at moving from Exchange 2007 to O365 and abandoning Exchange altogether, but we're still months off, so I'm stuck maintaining the environment until then. The eight 2010 servers were just left in place (in the hopes that the project would move forward....) Thanks, Jonathan On Tue, Jun 3, 2014 at 4:15 PM, Michael B.

Meant to include - both servers have OWA enabled for their respective users. EWS is published (https://mail.domain.com/ews) Both sites present challenge dialogue, and once authenticated, both present this: Directory Listing Denied This Virtual Directory does not allow connections to be listed.

Have not been active in a couple of years. I'm hopeful someone here can help me out. My Google-fu is failing me.... I have [inherited] two Exchange 2007 Servers running SP3 with the latest rollup (I got them updated from SP2 back in October) these servers are in two separate sites. Each server holds all the roles, and we're just passing HT traffic between. Each sends their own email out their local connection, but all inbound traffic comes in through Site1. The mailboxes are split about 50/50 between the two servers. Anyway, we have been receiving the following event on both servers for some time. We are NOT getting event ID 17 on either server (as just about everything I've googled turns up). on each server, the event says "none of the CAS servers in [the remote] site are responding". If you have any suggestions on how I can resolve this, I'd be very grateful. Event Type: Error Event Source: MSExchange Web Services Event Category: Core Event ID: 11 Date: 6/2/2014 Time: 9:58:19 PM User: N/A Computer: EX01Site1 Description: CAS server EX01Site1 failed to proxy EWS to AD site CN=Site2,CN=Sites,CN=Configuration,DC=DOMAIN,DC=CORP because none of the CAS servers in this site are responding.
