Thanks everyone for your additional feedback. The engineering team is working on this as part of Skype & Teams convergence.Chris commented
Glad to see this is being worked on hopefully actively. I have the same issue with a minor twist - in that Teams will not allow me to change my status to any other option - it's perpetually stuck on out of office - even when I'm logged in have a free calendar and my Skype status is set to available. I'm not sure where it's getting the status from but if I cannot modify it by sitting in front of the computer and manually changing it it's a bit concerning.
