“Hey chad – Can I give someone the right to my server based archives on Exchange 2010?”

When a user leaves an organization, it’s common to provide access to his/her mailbox to other users, including the departed user’s manager or supervisor, or another user assuming the departed user’s responsibilities. Delegate access is also provided to allow one or more users to access a shared mailbox, or to allow executive assistants to access mailboxes of executives they’re assisting.

In Exchange 2010 SP1, when you assign Full Mailbox Access right to a mailbox, the delegate you assign the right to also has access to the user’s personal archive. To enable access to the user’s personal archive (in addition to the primary mailbox), you must assign the Full Mailbox Access right from an Exchange 2010 SP1 server. Additionally, delegates must use Outlook 2010 to access their mailbox, and must connect to an Exchange 2010 SP1 CAS server for AutoDiscovery. When delegates access Exchange 2010 SP1 with Outlook 2010, both the primary mailbox and the personal archive of mailboxes they have access to are automatically added to Outlook 2010.

So you may not be able to JUST give access to your archive, but it’s possible.
