[from the article]

    *" I was using my personal phone at work to do some testing related to Microsoft Exchange ActiveSync. In order to monitor the traffic, I had configured my phone to proxy all HTTP and HTTPS traffic through Burp Suite Professional - an intercepting proxy that we use for penetration testing - so that I could easily view the contents of the ActiveSync communication.

    Looking through the proxy history, I saw frequent HTTP connections to ws-cloud112-blur.svcmot.com mixed in with the expected ActiveSync connections."*

Whoever said that this has nothing to do with ActiveSync; You are being disingenuous.
