Answer 1

This small PLUG-N-COMPILE-RUN (woo-hoo!) Java Class should demo getting to a room resource user calendar of events. The Azure V2.0 REST API is not currently allowing one to do so. Make sure that the auth-user that authenticates to the Exchange service is a "delegate" to (or of) the room resource user calendar whose events you want to retrieve. Your Exchange/Office365 admin might need to set that up for you. I grabbed the Java EWS API here: Index of /maven2/com/microsoft/ews-java-api/ews-java-api/2.0/ ews-java-api-2.0.jar and the javadoc.jar which was a great reference. You can also use Maven, Gradle or other methods to integrate the API into your code if you go to the Github repo: https://github.com/OfficeDev/ews-java-api. The Getting Started Guide is...well...words escape me (for good reason). Put it this way, you'd better use your search engine a bit in order to figure out how to do other stuff! And looking through the classes in the Javadoc helped me a good deal. Enough blah-blah-blah... On to the code: (oh, I included all of the imports! I always hate it when I get a sample snippet of code and I have to go hunting and pecking for the imports. I still leave it to you to get hooked up the the actual libraries, though! You're not in code-diapers anymore, if you can get this far! ;-)
