Bookings: Drawing free/available data from multiple calendars...

Timothy Lessing 

I have the same problem. I was somehow able to get one of my Gmail accounts connected so that it did not show those calendar items as available in Bookings. But since I have 2 Gmail accounts/calendars in addition to my Outlook/MS365 one, it only works with one. 

Here's how I got the one Gmail account to sync in Bookings:

1. Go to MS365/Outlook Calendar on web

2. Click Add Calendar

3. Choose Add Personal Calendar

4. Connect your external calendar (mine was Google/Gmail)

5. Make sure the option is ON for "Include in My Work Availability"

This is how I was able to sync ONE external/non-Outlook calendar to Bookings. Anything from that Google account shows both on my Outlook Calendar and availability is reflected in my Bookings page. 

I still have ANOTHER Google account that shows appointments in my Outlook 365 Calendar, but only through the calendar webcal subscription. That account does not impact my Bookings availability.
