What do you mean by "long"? I prefer to set it to run every 30 days
and prompt me. That way I can take a look at the PST files and see
what's happening.
More (or much more) than 1 day. The items that become eligible per the
folder's auto-archive settings are not actually archived until the
global setting's run interval. Say you set the folder to archive items
that are over 5 days old. If the global archive run interval is 30
days, those 5-day old items become 6 days old, 7 days old, 8 days old,
and so on until the next archive job runs after 30 days have elapsed.
Items that you wanted to disappear won't do so until the archive job
gets run. So you want the global archive interval to be equal to or
shorter than the shortest archive eligibility set in any folder.
Having the folder's archive eligibility interval set to shorter than
the global archive run interval means those eligible items won't get
handled until the archive job actually gets around to be ran (manually
or by using the global archive interval). So you end up wondering why
eligible items aren't getting archived on time. Set the global archive
interval to 1 day. Then set the folder's archive interval to whatever
you want and its eligible items will get archived then. For example,
with global archive interval at 1 day and the folder's archive eligible
archive at 30 days, the items in that folder don't become eligible for
archiving until they are 30 days old but they WILL get archived at that
time because you don't have to wait longer for when the archive job
actually gets run.
