Hello,
We are currently running Exchange 2013 SP1 co-existence with Exchange 2010 SP3 Rollup 4.
Our Outlook Anywhere and OWA are pointed towards Exchange 2013 CAS servers.
User mailboxes are still on Exchange 2010.
Outlook Anywhere with Exchange 2010 mailboxes are able to connect via Outlook 2010.
The only issue is when Outlook Anywhere is being used from Internet or from Internal network and user goes in Outlook 2010 -> File -> Automatic replies get the following error: -
"Your automatic reply settings cannot be saved. The server might be unavailable, or your automatic reply message might have exceeded the size limit on the server"
This only occurs if connection goes via Exchange 2013 SP1 CAS server. It was working before and it seems it just broke down since we upgraded to Exchange 2013 SP1. In HTTPProxy EWS logs on Exchange 2013 SP1 CAS server I see this when I re-create the issue on Outlook 2010.

=========================
I have checked and double checked using https://testconnectivity.microsoft.com/ and there are no issues in "EWS".
It works fine if user mailbox is on Exchange 2013 Sp1.
I was wondering if anyone has co-existence of Exchange 2013 SP1 and Exchange 2010 SP3 could you please test Exchange 2010 mailbox via Outlook Anywhere and see if you could re-create this issue. After spending a week on this I wonder if it is some sort of bug in Exchange 2013 SP1.
Thanks,
Raman
