This is good. I had originally looked at using Microsoft Bookings for this but it's really not designed for it.
As part of our Covid management we have three things
1) Number of people on the floor of the building will be limited
2) Number of people in a shared office space will be limited
3) Our facilities company need to be aware of what floors and offices are in use each day so that they can be cleaned in the evening.
It would be great if we could connect or limit office space by number of people on floor. I could probably use Power Automate for item 3 but again, would be great if that could be linked too. I imagine most companies would be doing similar in offices?
Edit: would agree that using the customattribute is unfortunate.
