Exchange 2010 upgrade

We are in the process of an Exchange 2010 upgrade and I'm starting move migrate mailboxes from our Exchange 2003 servers to the new Exchange 2010 servers.  I have a couple of questions regarding Outlook Web App (formerly Outlook Web Access).

1. When a user on Exchange 2010 tried viewing the calendar of a user on Exchange 2003, all they see is "Busy" or "Away" for apointments/events.  If they view the calendar of someone else that is on Exchange 2010 they can see what the appointment or event is.

2. I am unable to book a resource

I do not have the issues above when using Outlook on any computer.  The issue only comes up when using Outlook Web App.  Any suggestions?  Thanks!

When transitioning your supposed to direct all owa to the exchange 2010 client access server then configure a legacy URL back to exchange 2003 this because exchange 2010 cannot correctly render mailboxes still on exchange 2003 and vice versa.

Did you configure a legacy URL?  

also check EWS permission on IIS
