The client connects to the mail front-end to access the server through RPC, and now the CAS and mailbox roles are basically separated. The default is random. If a CAS server has a large number of mailboxes, the RPC service will die. Then the outlook client will have an unresponsive state. So sometimes we need to specify a CAS server for some user mailbox databases. The following command updates the mailbox database so that all mailbox client connections in the database access the server or the server array through the client. You can also use this command to change the client access server or client access server array that the client uses to connect to the Mailbox server. Set-MailboxDatabase-RpcClientAccessServer

Using Exchange 2010 Management Shell:

Change RPCClientAccessServer Attribute to be FQDN of Exchange 2010 Mailbox Databases (repeat for all Databases on Exchange 2010)

Set-MailboxDatabase-Identity ""-RPCClientAccessServer ".. local

Using Exchange 2010 or 2013 Management Shell:

Change SCP Object for Exchange 2010 to Point to Exchange 2013 (repeat for all Exchange 2010 CAS Servers); set this to whatever your internal AutoDiscover namespace is.

Set-ClientAccessServer-Identity "servername"-AutoDiscoverServiceInternalURI https://outlook.domain.com/autodiscover/autodiscover.xml

Using Exchange 2010 Management Console:

Set Exchange 2010 Outlook Anywhere to NTLM (repeat for all Exchange 2010 CAS servers)

EMC-Server Configuration--Right Click-Properties-Outlook Anywhere Tab- Change Authentication method to "NTLM"

Using Exchange 2013 Management Shell:

Temporarily adjust Authentication Method on Exchange 2013 Outlook Anywhere to be NTLM (required for users on Exchange 2010)

Set-OutlookAnywhere-Identity "\ rpc (Default Web Site)"-InternalClientAuthenticationMethod:Ntlm-IISAuthenticationMethods Basic,Ntlm,Negotiate-SSLOffloading $false

Once Exchange 2010 has been removed and uninstalled, run the following command to reset authentication.

Using Exchange 2013 Management Shell:

Adjust Authentication Method on Exchange 2013 back to Negotiate

Set-OutlookAnywhere-Identity "\ rpc (Default Web Site)"-InternalClientAuthenticationMethod:Negotiate-InternalClientAuthenticationMethod:Ntlm-IISAuthenticationMethods Negotiate-SSLOffloading $false
