This morning, folks in our organization reported that they now see random new calendars in their list of calendars. The calendars appear to be copies of other employees' calendars. It shows in it's own calendar group titled "Team: 'Person Name'", and for me at least there are two calendars there for other people in my organization. I am seeing a new group in my outlook that says "Team: Person Name" with two calendars in the group, one that belongs to the person in group name, and another for a completely different employee.
No one has shared these calendars with each other; they have appeared automatically and now employees have access to other employees personal calendars?!
