accessing other mailbox "sent items " &"deleted items" folders as a delegate

Yes, you can give someone permission to any of the folders in your mailbox, but you have to assign permission to each one individually.  You must:

1.  On the "sharer's" machine right click on Mailbox->choose Properties, then go to the Permissions tab.  Add the "sharee's" name and the level of permission you want to give them.
2.  For each folder you want to give them permission to, repeat step #1 for that folder.
3.  You can only access the default folders in someone elses mailbox using FILE->OPEN->ANOTHER USERS FOLDER, so if you need to access any subfolders or what not you will need to:
     a.  on "sharee's" machine bring up the Exchange Server Account properties (the steps vary depending on the version of Outlook, reply back with your version if you are not sure how to get here).
     b.  under the Advanced tab there is an option to "Open these additional mailboxes", click ADD and add the "sharer's" alias, click OK.
     c.  the next time the "sharee" opens outlook they will see any folders they were given permission to in their folder list (don't see folder list?  click View->FolderList in most versions).
