Import and Export of PST Files
Allow the Administrator to be able to Import a PST file into an account as well as export a PST File for an account from the Admin Console.
This would reduce migration time considerably as well as allow for a 'Snapshot' like archive of a specific user for compliance or other specific needs.

we are migrating from a hosted MS-exchange environment. Therefor we don't have administrative access to the exchange server and the only way to migrate our mail files is by importing pst files from clients.
Due to the much slower upload speed in our DSL network it would be a great advantage for us, when we could import the pst-files at server side.
