I would love to see a basic IMPORT/EXPORT feature added so that individual mailboxes could be dumped to .PST files. As someone who has worked and provided support in an MS Exchange environment for years, and in various Lotus Notes Environments for decades, being able to quickly and easily dump a users mailbox, contacts, and calendar to a standard file format has saved my butt many many times. At the very least I will export my own and my direct superiors mailboxes prior to any major hardware or software upgrades.
