OLM to PST? Calendar?

Hi all,

Is it posible to convert an Outlook 2011 Export(*.OLM).
To a Windows Outlook/Exchange supported file.

I need to export a Calendar from a Entourage pop account.
to a Exchange 2010, Outlook 2011 config. The Agenda needs to be available in the Exchange web interface.

So I need to import it to exchange.

I need help! pleasee!!!!!
