On our exchange server the admin had put the setings so that all
deleted messages will be deleted the day after. How can I copy all
messages to another folder localy on my machine before they get
deleted by the exchange rule?
Use a rule that saves a copy of all received mails (after passing
through any anti-spam rules) into some folder. Any whitelist or
organizational rules move a copy into this other folder. If the mail
makes it past the gauntlet of your anti-spam rules, end with a rule to
save a copy of the mail into this other folder.
I created a "Received Items" folder that is under the "Sent Items"
folder. The whitelisting rules move a copy into the "Received Items"
folder. If the mail survives past my anti-spam rules then the last
rule moves a copy of the received mail into the "Received Items"
folder. Doesn't matter that I delete the original from the Inbox
folder since a copy is still in the Received Items folder. I made it
a subfolder under Sent Items because I could then do a search starting
at the Sent Items folder, the search includes subfolders by default,
and the results would include both the sent and received copies of the
mails (which I could group using the View in the search results
window). Some folks just move the copy of sent and received items
into the same folder (and sometime just reuse the Sent Items folder)
so they can group the related mails whether they were sent or
received.
Obviously it will be up to you to manage the items in the other folder
to where you moved a copy of received mails. If you just want to
expire them after a longer interval than what the Exchange admin
provided, use auto-archive to delete the items in this other folder
that are over N days old (you get to pick the value of N).
Obviously the above only works for received mails that you later
delete, but then all mails that you have were received sometimes. It
won't help if you delete items that were received before you used the
above rule to save your own copy elsewhere, but then you could move a
copy of those older items into this other received/pending folder to
catch up.
One day seems a bit overly short for deleted mail recovery. Have you
actually asked your Exchange admin about upping the retention
interval? Since the Exchange server should be getting backed up
daily, your deleted items should still be available in the backup that
was performed the day before the 1-day expiration for the deleted
items, so you might have to ask the Exchange admin for a copy of your
old e-mails from their backups. Pester them enough to do the
retrieves from backups and maybe they will be more compliant to
increasing the deleted items retention interval.
