Therefore, the address of this server is referenced by the RpcClientAccessServer mailbox database property. When you uninstall the Exchange Server Server 2010 CAS role from this server, the RpcClientAccessServer property is not changed. The mailbox database property still references the original Exchange Server 2010 server address, even though Exchange Server 2010 CAS is not installed on that server.
- You uninstall the Exchange 2010 CAS role from the server. However, the uninstall process does not completely remove all the settings. The RpcClientAccessServer mailbox database property still references this server address.
