Allow room calendar to be overbooked till a certain number?

[Parmanu]

Hello everyone, my first post here.

I have created a room calendar in Office 365 and I want it to be overbooked till (lets say) 5 meaning it can be booked by 5 of our staff without any rejection. As soon as 6th staff tries to book it, rejection email should be sent to that staff. All 5 staff names should be visible in the calendar.

Similarly, in another room calendar booking limit could be 7 meaning up to 7 staff bookings will be allowed.

Is this possible? I have looked at tons of resources on web but can't find any relevant information.

Depends on the details. You can play with the calendar processing settings of the mailbox and specify a maximum number of conflict instances via the corresponding parameter, but also take in consideration the ConflictPercentageAllowed value. Refer to the cmdlet help for more details: https://docs.microsoft.com/en-us/graph/api/authenticationmethod-get?view=graph-rest-beta&tabs=http

Or just configure a delegate and have him manually approve individual instances as needed.

Thanks @Vasil Michev Vasil for responding. I know about the delegate feature but I want to automate this task and hence avoid doing it.

Ain't conflict and conflict % parameters meant for recurring bookings only or are they meant for standalone bookings also? Also, the link you have shared is for Microsoft Graph. You sure about the link?

Whoops, that's what happens when I try to multi-task :) The link is to the cmdlet help, and yes the conflict parameters only apply to recurring meetings.

Okay. So I tried both no of conflicts and conflicts % parameters but nothing worked for me. Individual bookings were still accepted despite going beyond number of conflicts allowed.

Any other way out? Anyone?
