Separate Out of Office status from Presence (like Skype)
Allow users to offer their presence of choice while keeping the Out of Office indicator persistent.
Users may have special projects / exceptions / reasons that require them to temporarily login and publish their status, while otherwise not in the office.
In Skype, a user can login and show available for a quick interval - without having to disable their Out of Office in order to extend that presence.
This dual context would be useful in Teams.
