The settings that used during Exchange Server journal mailbox archiving come from the Exchange Journaling policy that is being used. There is a default Exchange Journaling policy that you can edit as required. Alternatively, you can create further policies as necessary, and set a different policy as the default policy.
To review the default Exchange Journaling policy settings
In the left pane of the Administration Console, expand the Policies container.
In the right pane, double-click Default Exchange Journaling Policy.
Check the settings on the Advanced tab, and change them as necessary.
You can click each setting to see a description of what it controls. The settings are described in the online help in the Administration Console and in the Administrator's Guide.
