We have a written policy that says all mail past 60 old days will be deleted. With 2003, this used to be an easy, although manual, task of complying. Microsoft has messed that up from what I can tell. I currently run Exchange 2010 14.2 (Build 247.5). Here's what I have tried:
1. Retention Policy - This is a great idea but doesn't work in practice that i can see. I created tags for Sent, Inbox, Deleted and User Folders and applied them to a policy. Two problems with this: 1. Deleted Items never clear, not even after a couple of weeks. 2. User Folders also gets Notes and that's no good.
2. Tried Power script command: Search-Mailbox -Identity "MailboxName" -SearchQuery "Received:> $($Today) and Received:(Today)" -DeleteContent -force where $Today is a date variable. Works great but once again attacks the Notes and I have to set a script to run against every mailbox.
3. Third party application - They all seem to run PS scripts in the background so essentially are GUI versions of #2
Now, I'm down to the last thing I can think of...let Outlook do the work. I'm looking for a way, without having to visit every client, to set Outlooks Auto-Archive on each default folder to delete anything older than 60 days. I'm looking at the GPO ADMX templates for Office but I don't think they will work. Seems to me that those settings are server side since the Auto-Archive setting do not change even if the user switches pc's.
I just need a way to delete all but 60 days of email out of the Inbox, Deleted, and Sent with the ability to exclude certain mailboxes. Does that even exist anymore???
