Hi @Erwin Maas ,
According to your description, sounds like you would like to import or sync your Outlook calendar to your Microsoft Bookings calendars, right?
If yes, I'm afraid that features like this has not been supported yet.
Outlook calendars and MS Bookings calendars are two different calendars. Just as I tested, what we can do is to sync the appointment created in Bookings to Outlook, it's infeasible for us to sync calendar created in Outlook to Bookings.
If you still would like this feature, I would suggest you to vote for this User Voice thread, Microsoft may notice it and add it in the later version.
By the way, if you would like to learn more information about Microsoft Bookings, please kindly understand that here we mainly focus on general issues about Outlook desktop client and know little about MS Bookings. To better solve your issue, you could try to post a new thread to the dedicated forum for Microsoft Bookings.
The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thanks for your understanding and hope your question will be resolved soon.
