Suppose you linked a Office 365 which has 4 sub-calendars. You’d like FreeBusy to ignore all events in the Birthdays and Unites States holidays sub-calendars when calculating availability.
To do so:
Go to the Calendars & Integrations page.
Find the calendar you wish to manage.
Uncheck the subcalendars that you want FreeBusy to ignore and click Save.
