Re: mail extension can't connect to exchange server

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)
