OWA is just a view on an MS Exchange database. It doesn't contain data itself.

So your problem seems to be: how to forward mails from your institutes MS Exchange server to your gmail account. The obvious disadvantage of forwarding, by the way: you loose the original sender and the original timestamp.

Our policy in these forums is to respect regulations from employers. So we won't help circumventing them. Just contact your IT dept and ask them how to do it. My guess is they will say: not allowed.

So I'm locking this thread.
