Currently, we are using the opensource MRBS (Meeting Room Booking System) to book various meeting rooms. Since we plan to move away from MRBS and use the ZImbra's Resource feature, it's noticed that the meeting room bookings feature in it has some inherent constraints as it does not display the status of the meeting rooms which are booked.

If I wish to book a particular resource/room at a particular time, it shows a pop-up about the conflict but nevertheless, allows me to save the booking and only after that an email with the subject line "Decline:" is received by the person booking the room.

Please can someone let me know if there is any way to integrate the opensource MRBS (Meeting Room Booking System) application or any other such application. If not, then is there a way to see the status of the bookings of the meeting rooms in Zimbra.

Thank you in advance.
