Hi @Alexander
Thanks for sharing the issue in detail. I’ve taken time to investigate this topic thoroughly, and based on the information available, if your setup follows Microsoft’s recommended configuration, then the issue you're facing may reflect a limitation or inconsistency in how Bookings handles calendar sync, especially in organizational environments.
During my research, I found that many users are experiencing similar problems, which suggests this may be a broader issue that Microsoft needs to address more directly.
I strongly suggest submitting feedback to Microsoft via the Feedback Portal. There’s already a post describing this exact issue: We would like to see Microsoft Bookings implement the ability to prevent duplicate reservations for resources specified as “locations” on the Services page. · Community You can upvote the post to help increase visibility. I’ve already voted for it myself, and I truly hope that with enough user engagement, Microsoft will prioritize a fix or provide clearer guidance. Here are some related threads and documentation that may offer useful insights:
