Folder design properties include permissions, rules (rule: One or more automatic actions taken on e-mail messages and meeting requests that meet certain conditions, along with any exceptions to those conditions. Rules are also referred to as filters.), description, forms (form: A way to distribute and collect information electronically. For example, a form can be available for anyone to order supplies or to post information in a public folder. All Outlook items, such as messages and appointments, are based on forms.), and views (view: Views give you different ways to look at the same information in a folder by putting it in different arrangements and formats. There are standard views for each folder. You can also create custom views.).
