By default, Exchange room calendars only show the name of the person who booked the room — not the meeting title or details. This behavior is meant to protect privacy, but in many environments (like shared workspaces or support teams), it’s actually more useful if everyone can see what the room is used for.
We can fix this by adjusting the room mailbox settings via PowerShell.
Connect to Exchange Online
Install-Module ExchangeOnlineManagement
Connect-ExchangeOnline
Update calendar settings
Set-CalendarProcessing -Identity “[email protected]” -AddOrganizerToSubject $false -DeleteSubject $false
This will:
- Keep the original meeting subject
- Stop replacing it with the organizer’s name
Optional: Set that everyone can view items
Set-MailboxFolderPermission -Identity “[email protected]:\{Agenda or Calendar}” -User Default -AccessRights Reviewer
