How to provide more visibility to Exchange room calendars rather than just free/busy.

By default the room calendars / resouces only provide basic free/busy visibility. Sometimes you might want to provide more info than that e.g. subject, user etc. To do this log into ECP, provide a user full access to the calendar, then inside outlook for that user change the permissions

Open ECP, click recipients -> resouces -> the room you wish to change -> Add full access

Change the default permissions, click OK and now users should have access to the permission level you set.

Notes

By default when creating a resource booking exchange will replace the subject with the owners name to change this, run the following power shell commands to disable this functionality.

First check that DeleteSubject and AddOrganizerToSubject directives are set to true by running the command below;

Exchange 2013+

Get-CalendarProcessing -Identity "THE RESOURCE NAME" | FL

Exchange 2007

Get-MailboxCalendarSettings -identity "THE RESOURCE NAME" |FL

Disable the above for the mailbox

Exchange 2013+

Set-CalendarProcessing -Identity "THE RESOURCE NAME" -DeleteSubject $False -AddOrganizerToSubject $False

Exchange 2007

et-MailboxCalendarSettings -Identity "THE RESOURCE NAME" -AutomateProcessing AutoAccept -AddOrganizerToSubject $False -DeleteSubject $False
