Your exchange-Server is telling you what’s wrong:

Could not retrieve folders. ErrorAccessDenied: 

Are you sure that the account you’re using has the needed rights to access to ressources you try to get?
Normally internal server errors are the remote site (so your exchange-server), maybe your logfiles on the server give a further hint.
