DWORD with value "1" or "0".

Description

If custom filtering is implemented, and Override is set to 0 (zero), then the Exchange archiving task processes the archiving rules for all messages as normal for user mailbox and public folder archiving before it processes filters. You can prevent the Exchange archiving task from processing archiving rules by setting Override to 1.

See the Setting up Exchange Server Archiving manual.
