When are Exchange/Outlook Calendar events treated as busy in OnceHub?

Exchange/Outlook Calendar has a number of different availability configurations. This setting can be found by editing an individual event, in the "Show as" field (Figure 1).

1. Free: OnceHub will not read this time as busy. This is useful when you want to indicate specific events on your calendar without having those events block your availability.
2. Working elsewhere: 
   1. Office 365 or Outlook for PC calendar integrations: OnceHub reads this time as busy and blocks availability.
   2. Exchange integration through EWS: OnceHub will not read this time as busy. 
3. Tentative: OnceHub reads this time as busy and blocks availability.
4. Busy: OnceHub reads this time as busy and blocks availability.
5. Away: OnceHub reads this time as busy and blocks availability.

All-day events in Exchange/Outlook Calendar are set to Free by default. Regular events are set to Busy by default.
