Overview:
When using the Calendar Sharing Menu, users are able to access the calendar of any other user, and are not following the Role or Territory hierarchy for these users.
Root Cause:
Works as designed.
Solution:
User calendar sharing is not based on Role or Territory hierarchies. The Calendar Sharing Menu contains a lookup to the User object. Access to individual Users is based on the standard security model to the User object.
