The ARCHIVEID="<archive_ID>" option is only applicable if the rule action is ACTION="ARCHIVE_ITEM". Archive_ID identifies an existing, enabled archive.
You can define a different archive for different rules. If you do not specify an archive, the default archive for the mailbox or public folder is used.
The extract below shows how the option might be specified in the ruleset file. In this example, any messages that satisfy the message attribute filters will be stored in the archive specified:
<RULE NAME="Example rule" ACTION="ARCHIVE_ITEM" ARCHIVEID="15165263832890493848568161647.server1.local"> <message attribute filters> </RULE>
