Block availability when busy

Busy times in your Personal Google Calendar will block availability

Requires a connected Google Account

Go to Availability > Google, notice that each Google Calendar record has a Personal field.

In this personal field you can select a Google Calendar in which events will block the availability for the source calendar.

More specifically, any event marked as BUSY will block the availability. This allows great flexibility, as you can still have some events in Google Calendar that you may choose not to block availability of your services, just by marking them as FREE.

How to set a Google Calendar event as busy/free? Just edit the event and choose its busy/free property.
