This is for a corporate Exchange account.  I have a rule setup (called Auto Archive) that says "If date received greater than 60 days, move message to Inbox (On My Computer)" 

Corporate policy is to remove mails from the Exchange server greater than X days old, so this archives them in my 'Inbox (On My Computer) folder.

A couple of issues/questions:

1)  Sent items > 60 days old *also* end up in the 'Inbox (On My Computer) folder.  How can I have Sent Items get archived in 'Sent Items (On My Computer)'?

2)  Given the folder hierarchy outlined above, if I wanted to create a 'Reference' folder for items I want to keep but require no response, where would I create it?

3)  Also, if I were to create a rule to for mails from distribution lists to go into a specific folder or rules for moving messages where I'm in the To: or CC: field, where should that folder get created?

I'm confused as to whether they should reside under the Inbox somewhere or within the second grouping of folders (Conversation History, quarantine, etc.).

Thanks!
