The team is happy to announce that this functionality is now available through the Presence Graph API which is now in public Beta! We have additional functionality planned for the API so please keep checking back for updates.
Please note that this is a beta version of the API and may be subject to change. Use of these APIs in production applications is not supported.

Microsoft, Please let us have the ability to use presence in Teams as I use my Blynclight to an extreme to let people know what my status is to stop interruptions.
