- Open the Exchange Management Console and navigate through the console tree to: Organization Configuration -> Mailbox
- Select Mailbox.
- Click the New Managed Custom Folder link in the Actions pane to launch the New Managed Custom Folder wizard.
- On the wizard's initial screen, enter a name for the managed folder that you are creating. For the purposes of this tutorial, name the folder Contoso.
In Figure 1, you will see that there are other empty text fields. One field is the name that Microsoft Outlook users will see. You can configure the folder so that users see a different name than what you have actually named the folder in the Exchange Management Console. Typically, you would want to use the same name in both fields.

The text box in this screen allows you to enter a comment when the folder is viewed in Outlook. Here you can enter more descriptive information regarding the folder's purpose. In this example, you might enter:
This folder will be used to store messages related to the Contoso project. Items in this folder will be retained for five years.
There is a checkbox that you can use to limit the size of a folder and its subfolders. This prevents a folder from outgrowing the hard disk onto which the data is stored. If long-term message retention is your goal, then you typically wouldn't want to limit the folder's size.
There also is a checkbox at the bottom of the screen that can be used to prevent users from minimizing the comment you entered into Microsoft Outlook. Keep in mind that this checkbox is only effective in Outlook 2007.
- Click New to create the folder.
- When Exchange finishes creating the folder, click Finish. The folder that you have created will now be listed on the Managed Custom Folders tab (Figure 2).
