Skype for Business offers instant messaging, screen sharing, and video conferencing. It integrates with the Microsoft Office suite of applications and is safe for Protected Health Information (PHI). It is available as a "client" (i.e. installed on Michigan Medicine devices) and as a mobile app for iOS and Android devices.
With dial-in conferencing, you can easily set up or join an online videoconference directly through your Outlook calendar. Simply select "New Skype Meeting" in your Outlook calendar to begin. Have a look at all the features in the Skype for Business: Dial-In Conferencing Quick Reference Guide.
