Creating resource rooms in EXCHANGE 2013 can be complicated as the GUI doesn't work in a straight-forward manner.
Here's how I did it:
- New-Mailbox -Database "Mailbox-FOO" -Name conference.downstairs -DisplayName "Conference Downstairs" -Room
- Set-MailboxFolderPermission conference.downstairs:\Calendar -User Default -AccessRights Reviewer
- Set-CalendarProcessing conference.downstairs -AutomateProcessing AutoAccept
This will allow users to set an appointment with the ROOM as the LOCATION but will only allow the ORGANIZER to adjust the appointment (rather than letting anyone change the appointment).
