This section describes the automatic method of adding a public folder. You add an Enterprise Vault "auto-enabler" that then enables folders that are immediately beneath the folder you specify. These folders and their subfolders are all enabled for archiving.
By default, a separate archive is automatically created for each folder at this level.
To add a public folder auto-enabler
In the left pane of the Administration Console, expand the hierarchy until Targets is visible.
Expand the domain that contains the Exchange Server that hosts the folder you want to add.
Expand the Exchange Server that has the public folder you want to add.
Right-click Public Folder and, on the shortcut menu, click New and then Public Folder Auto-Enabler.
