Additional features, settings, or issues not covered by specific Microsoft Teams categories
I'm having the exact same issue, and my calendar for today is blank (lucky me) so therefore it is not the 'still not fixed bug' of any appointment/meeting (whether accepted or not) being set as Out of Office.
I think this is simply a bug whereby Teams doesn't realise my Out of Office in Outlook is now off!
Any danger of Microsoft fixing this?
My wife has just informed me that they are continuously having the same issue at her place of work too.
