Setting Exchange Calendar Permissions

The default permissions for all users to another user's calendar is AvailabilityOnly. This permission allows you to see that a user is busy, but it does not allow you to see the subject or other information. This permission is just enough that you can use free/busy searching for meeting requests.

In some cases, you might want to make the subject available. Specifically, for resource mailboxes, it may be useful. In the default configuration, meetings in the calendar of a resource mailbox contain the name of the person that organized the meeting, but not the original subject of the meeting. By allowing users to see the subject of meetings for a resource mailbox, you are allowing them to see who organized the meeting.

The permission to use for showing meeting subjects is LimitedDetails. The command to set this permission on a resource mailbox named Room100 is shown below:
Set-MailboxFolderPermission Room100:\Calendar -User Default -AccessRights LimitedDetails
