Managed Folder Assistant Not Archiving

Hi, I recently migrated from a legacy Exchange 2003/2007 environment to 2010.  However, I'm unable to get messages archived using Managed Folder Assistant.  Here's the history:

1. Created test user and enabled archiving on that account.  (This was a test user used for a couple of months during the migration).
2. I created a Retention Policy Tag on the Deleted Items folder set to 7 days.  Set Action to "Delete and Allow Recovery".  Saved and closed.
3. Re-opened the Tag and changed "Delete and Allow Recovery" to "Move to Archive".  Saved and Closed.
4. Ran "Start-ManagedFolderAssistant -identity <email address>"

Here's what happened afterwards:

1. I open the user's mailbox in Outlook 2013, clicked the Deleted Items folder, then clicked the Folder ribbon.  I then click the "Policy" button, and it shows the correct policy.
2. In the Deleted Items folder, all the messages are still there, but those older than 7 days are marked "This item is expired."
3. There is nothing in the "Deleted Items" folder under the "Online Archive" mailbox.

Any ideas would be greatly appreciated.

Thanks,

David
