Business Productivity Online Suite BPOS has quite a few commandlets that are available however I'm really stumped when it comes to importing a .pst file.  I have tried the get-XsExchangeMailboxdata commandlet in every way possible but I can't seem to figure out how to get it to import.  Is this a configurable solution?  There are many posts about importing .pst's into the outllook configured with BPOS to get the data to the cloud however not much on directly running an powershell command to import the .pst data.  Anyone have suggestions?
