Room mailbox not sending approval to organizer

Sílvia Carmen 96 Reputation points

We have an hybrid environment using O365 with exchange online and Exchange Server 2016 on prem. I went to Exchange 365 Admins Centre and created a resource room mailbox and made myself a delegate to the room. this means I have to approve all the meeting room requests, which is exactly what I am looking for. When someone schedules a meeting to that room, I do receive an email asking for meeting approval and the person who requested the meeting receives an email from the meeting room saying approval pending. However, once I approve the meeting, the organizer does not receives any notification saying the meeting was approved. Is there something I am missing? Any help is appreciated. Thanks in advance.

    Thanks KaelYao-MSFT, if figured it out!

    The problem was I have created the room resource in Exchange on-prem and not on the cloud.
    So, yesterday I deleted it and created again but in Exchange O365 Admin Center on the cloud and now it's working as expected.

    Thank you so much.

    Kael's answer sent me in the right direction. I found that the parameter "TentativePendingApproval"was set to True.

    Once I ran this command, everything worked as planned:

    Set-Calendarprocessing -identity <room mailbox name> -TentativePendingApproval $False
