This is an issue with serialization data signing on your server. It is possible the Auth Cert isn't properly configured on all the servers. Please run Health Checker and the Monitor Exchange Auth Certificate script on the server.

After doing this, you may need to restart IIS or reboot the computer to get the desired results.
