What version of Java do you have installed on the Thingworx server? Who is the certificate authority for the cert on the Exchange server?
I know that there were some changes in how the certs are formatted/validated that can break in this way. I would recommend updating the Java version on the Thingworx server to:
- Java 7 >= 7u111
- Java 8 >= 8u101
And then restarting Tomcat (make sure that Tomcat's java opt are set to point to the new JVM)
