I want to view different mailbox properties, how can do that ?

Get logged into your control panel, In the Quick Access click on the e-mail icon.
A new form will appear where, you will see Mail control, Mail Service, Object and Properties form. Under Objects you can select any of existing mail resources, or if you click on the link Add new mail resource you can add a new one.
If you click on the MAIL BOX icon next to any mail box, page will refresh, and under Properties column, you will find all properties of that mail box.
