looks like Dodo beat me to it! ;)
If you are age based the task will continue to make multiple passes through the enabled mailboxes looking for archived items. By default, it grabs a 1000 items per pass(for EV6 and above).
If you are quota based the task makes one pass through the mailboxes. This is due to the fact it makes its initial calculation at the beginning of the archive run. Quota based can be precarious, and will most likely need refining to get right.
I always recommend age based to get the mailbox to where you want it. Then, if you have to, use quota to maintain it.
Are you asking if you enable a mailbox whilest the archive run is occurring? To be honest, it never occurred to me to try, but I would speculate it would not be processed till the next archive run, because it would need to be synchronized to let EV know it is enabled. --pure speculation ;)Message was edited by:
