I hate Microsoft Exchange/Outlook's calendar system (integrates with Skype for Business/Teams) for that. A person can be scheduled in for an hour's long meeting but it actually only takes 10 minutes, but you check the person's status after the 10 minutes and it still says 'In a meeting' (usually differentiates with 'In a call' if they're actually in a call, but it's quite unreliable and you don't know if maybe they're having technical problems and are just about to reconnect).
