An Exchange Public Folder task archives public folder targets. A public folder target is a single public folder hierarchy, starting from its root path and working down. You can have a few, or many Exchange Public Folder tasks, as required. Each Exchange Public Folder task can process multiple public folder targets.
The Exchange Public Folder task processes all folders beneath each target's root path, except for folders that are processed by another Exchange Public Folder task and folders that have had their Enterprise Vault properties changed to stop the folder from being archived.
You can add a public folder target with a root path that is higher up a public folder hierarchy than the root path of an existing public folder target. You cannot add one with a lower root path.
If you use Outlook to view the properties of the public folder, you can copy the folder path to the clipboard and then paste it in as the root path for the target public folder.
There are several ways to add public folders: manually or automatically.
Manual (standard) method. You select the public folder and the archive that is to be used for it. The same archive is used for the folder and its subfolders.
Automatic method. 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.
For example, if you add an auto-enabler to \myPublic Folder, then new archives will be created for \myPublic Folder\Finance and \myPublic Folder\Property. No archive will be created for \myPublic Folder\Property\Commercial because that folder will use the same archive as its parent (\myPublic Folder\Property).
Alternatively, you can select an existing archive to use.
If new folders are added later, they are automatically archived too.
