Additional features, settings, or issues not covered by specific Microsoft Teams categories
I too am suffering this issue. I returned today from a 3 week medical leave, turned off OOO in Outlook. Skype for Business changed to available, Outlook changed to available, Outlook 365 changed to available, but Teams remains on OOO. I have toggled OOO again in Outlook, Outlook 365, nothing makes a difference. Logged out of everything, rebooted, back in again, same behavior from Teams. I am still OOO and I have NO APPOINTMENTS in Outlook for the next 4 days.
Edit: Well after the better part of an hour, it finally changed its status...
