I'm having the same problem. I can add most people, but not one co-worker. I get the "This calendar already exists" message, but the calendar is clearly not there. It's not in the "Edit my calendars" section either.

I just had this problem. Turns out my colleague had not shared access in her setting to allow others in the organization to see her calendar.&nbsp;

This also just worked for me!! Deleted all Shared Calendars and added them back one at a time.
