Outlook 2011
Exchange Server 2007 has been set by Administrator to 50mb attachment size.

We are able to send large attachments when accessing Exchange Mail via the web, BUT unable to send the same attachment message from Outlook 2011 via the same Exchange account.

How do I configure Outlook 2011 to allow larger attachment sending?
I'm using MS Office 2011 for Mac.  I understand .PST files are no longer supported.  So how can i export mail out of my Exchange mail account (information store) and store them on a local disk only?
It is saving my Gmail account items onto my business exchange server which is putting me over their limit..this just started when i downloaed Lion.  Am I missing a step or should I reset the account loaded onto Outlook to correct the issue?  Any help is appreciated.
