I'm having some issues with room calendars. In our company we have several room mailboxes to allow users to book a meeting room. We've set up automatic handling of the booking requests so the requests are accepted/rejected when the room is available or not. Default users can only see when a room is available or busy, no further details.
However, the people who work at the reception desk should be able to also see the organiser and subject of the meeting, but not the details of the meeting itself. On top of that, they also need the permission to copy the meeting to their personal calendar so that the meetings show up in the calendar pane at the mail view.
I've already granted the reception full access rights to the mailbox of the meeting rooms, but that way they can see the details as well. I've tried removing all permissions and then sharing the calendar with them, with the permission to see the organiser and subject, but then they cannot copy the meetings to their personal calendar.
Is there any way I can set the permissions so that the requested setup is achieved?
We are using Office 365 and Exchange online with AD sync. The users and rooms are created in our on-premise AD. However, if it is easier, I can recreate the rooms in Office 365 (not the users though).
