I'm trying to setup the webpart "My Inbox" (OWA) in SharePoint 2010. It works when connecting to OWA running exchange 2007, but failes with error 400 not found when connecting to OWA running Exchange 2010. The error appears after logging in.
I'm using this url: https://<exchangeserver>/owa
I assume that this should be supported by Exchange 2010, but it seems to fail using this parameter /?cmd=contents.
