I’m sorry, but I don’t understand the question. If an event is created in a room mailbox and the subject is overwritten, there’s no way to get it back.

i managed to set that comments are visible for aprover, but only readonly (we need that this can be modified by administrator/aprover).

Set-CalendarProcessing -Identity room -addOrganizerToSubject $false -DeleteSubject $false -deleteComments $false -DeleteAttachments $false -OrganizerInfo $true

thank you.

I have no idea how you generated that JSON file so I have no idea how to include the organizer’s name in the output. I used the Microsoft Graph PowerShell SDK to generate the output for the room mailboxes report https://practical365.com/report-room-mailbox-statistics/. Maybe you could do the same?

Got any Ideas?
