That's good to know. Microsoft previously had a product called Microsoft Lync, which was HIPAA compliant (and was used as the chat protocol in my hospital system). It later became Skype for Business - although we still use it as Lync. I'm not certain if Skype for Business was ever considered to be HIPAA compliant however.
