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.
