We recommend that the Principle Name and Display Name correspond to the resource being setup (e.g. ConferenceRoom1). Under the Quick Add Exchange, the Access Level will need to be set to Full Access. No other information is required for a resource mailbox.

Users may now access the resource mailbox as per the permissions provided to them.
