Exchange 2010 sp2
I have managed to set up several room mailboxes in exchange, people are able to book the rooms and they get a response from the exchange server. this is brilliant.
however users are unable to view the calendar of the room mailbox to see what times are available, in a ideal world I would like users to only see if the room is free or not.
I dont want users to see the details of the meeting (title, description etc)
I have been trying to do this using the following command
Add-MailboxFolderPermission -Identity meetingroom -User "Usergroup" -AccessRights AvailabilityOnly -DomainController AD-Server
This throws the following error
Specified argument was out of the range of valid values. Parameter name: memberRights + CategoryInfo : NotSpecified: (meetingroom:MailboxFolderIdParameter) [Add-MailboxFolderPermission], Argum entOutOfRangeException + FullyQualifiedErrorId : CBC6516F,Microsoft.Exchange.Management.StoreTasks.AddMailboxFolderPermission
Any help on the situation would be brilliant, i have been trying to get this done for a couple of days and im going around in circles.
