Configuring Multistreamed Archiving for Exchange Mailbox

Multistreaming allows you to archive multiple mailboxes in parallel.

User Mailbox and Journal Mailbox: Each access node that is associated with the Exchange Mailbox server can have a maximum of 20 streams for each job. However, one service account can only use a maximum of 15 streams regardless of the value set for the subclient. If you need to use a higher number of streams, use more than one service account.


  1. In the navigation pane, expand Solutions > Exchange, and then click the Exchange_Mailbox_server.
  2. In the Agents area, click Exchange Mailbox.
  3. In the Content area, click mailbox_type.
  4. On the page that appears, in the General area, click Edit.

    The General dialog box appears.

  5. In the Max streams box, enter the number of streams that you want to use.

    If you do not want to archive multiple mailboxes in parallel, enter a value of 1.

  6. Click Save.
