Microsoft calendar integration

I’ve had experience setting up the Google Calendar app to work with a time field in the Ticket Fields, which will place a meeting notice on the due date in the Agent’s Google calendar.  I was hoping to do the same thing with a Microsoft user, but the Office 365 Calendar app only supports Tasks, Changes, CAB Meetings, and Allow agents to schedule meetings with ticket requesters.  Why doesn’t it work with Tickets too?  Am I missing something?
