Hello all 

Running Exchange 2013 sp1 RU8 and Exchange 2010 SP3. I know that Exchange 2013 does not client access array or the RpcClientAccessServer attribute.  However when i start introducing Exchange 2013 CAS\MBX servers do i need to change or modify  the 2010 client access array ? right now the client access array FQDN for the 2010 side points to "Outlook.mydomain.com" On the 2013 side the value for outlookanywhere is "mail.mydomain.com", and on the 2010 side the value for outlookanywhere is "mail.mydomain.com" Mail.mydomain.com" points to the 2013 CAS servers.  When a client connects I'm assuming its autodiscover that hands off to the client the FQDN name for the client access array?

Also it appears the admin before me created a value for RpcClientAccessServer attribute on the 2013 databases, because when i run the command "get-mailboxdatabase |select name,RpcClientAccessServer" I see "outlook.mydomain.com" stamped on all the 2013 databases. Can i remove this value from all the 2013 databases? if s

If you set the AD SCP and DNS records all pointed to the 2013 CAS, autodiscover will configure Outlook properly based on the mailbox locations.

Also it appears the admin before me created a value for RpcClientAccessServer attribute on the 2013 databases, because when i run the command "get-mailboxdatabase |select name,RpcClientAccessServer" I see "outlook.mydomain.com" stamped on all the 2013 databases.

Hi,

As Li Zhen clarified, Exchange 2013 has the RpcClientAccessServer attribute, but Exchange 2013 does not use this attribute. In others words, the RpcClientAccessServer attribute does not have an effect on Exchange server 2013.

Hope my clarification can be helpful to you.

Best regards,
