There can be many Exchange Public Folder Tasks. Each Exchange Public Folder Task process can archive one or more branches of the Microsoft Exchange Server public folder hierarchy.

When an Exchange Public Folder Task archives from a public folder it uses the archiving settings you specify in the associated Exchange Public Folder Policy in the Administration Console. You can, however, modify the archiving settings for individual public folders, by changing their properties from within Outlook, in the mailbox that owns the public folder. Enterprise Vault Outlook Add-Ins must be installed.

The Exchange Public Folder Task requirements are similar to those for the Exchange Mailbox Task; as it interfaces most directly with Microsoft Exchange Server and the Storage and Indexing Services, it makes most sense to install the task on the same computer as the associated Storage and Indexing Services. This reduces the amount of data that has to cross network links.
