Our company has the unfortunate luck of being around for 10+ years with no real limits on mailbox sizes. I have multiple Deleted Items folders with 15k+ mail pieces in them. My understanding is that if I apply the Retention Policy to those folders now, to let's say wipe items older than 1 year, since this is the first time retention tags would get applied, the first items would get deleted one year from now (unless I am mistaken here), instead of wiping right away any items that were already deleted over a year ago...
My idea was to set those tags, but in the meantime, come up with a PS script that would be run against most offending mailboxes to wipe the excess mail pieces to get us by till the Retention Policies start working their magic.
Has anyone ever attempted running such script? I have seen several ideas on line, but all the forums report mixed results... Is there another tool I could use to selectively/administratively wipe emails from few folders in other mailboxes, short of doing it from each user's Outlook?
