Dear Shane TEE
Good day! Thanks for posting in the Microsoft Community. We'll be happy to help!
First of all, we regret for the inconvenience caused to your work. Based on your description, I have a general understanding of your question, please first kindly refer to this official document to check whether it can help you Configure service availability | Microsoft Learn
In addition, if you still need further help, since your problem is related to Bookings, and our forums lack the tools and permissions to solve bookings problems, to help you better and not waste more time, I recommend that you also try to ask questions in Microsoft Bookings - Microsoft Community Hub. Technical engineers over there specialize in Bookings issues, and experts will focus on queries to further assist you.
Thank you in advance for your understanding. Your patience and cooperation will be greatly appreciated. I hope for all the best!
Sincerely
Kerry Chen | Community Moderator
