biztalk to pick emails without POP3adapter

Hi,
 
We are facing a scenario where an application will send e-mails to a particular account. And BizTalk needs to pick the mails and process them (parse though the message) and send it. We use POP3 Adapter to Receive mails. Is there any way in BizTalk can pick an email coming to an account on a Microsoft Exchange Server. The POP3 feature wouldnt be provided and policies restrict us to connect to an external POP3 account.
Is there any other alternative in biztalk?
 
Thanks!
