There is a team in my office that has a shared calendar (the team calendar is set up as a user in Active Directory/Exchange, so treat the team as a user). The team also has 3 sub-calendars for the different team members. Other people in the office need to be able to access this team's calendar. They can go to Open Calendar in Outlook and see the main calendar, but they cannot see the sub-calendars.
The sub-calendars all have the Default user permissions set to Reviewer.
If you go to File → Account Settings → Change [logged in Exchange account] → More Settings → Advanced and add the team's mailbox, it does show the calendars in Outlook, but it comes up under My Calendars instead of Shared Calendars.
We need to be able to go to Open Calendar and open the calendar and open all the sub-calendars this way. How is this possible?
