Outlook Web Access - Outlook 2010 and .mhtml - Block Attachment

I have SEPM 12.1.1101.401.  I have my reports set up through policies to go to my emails.  I access my emails through outllook(2010) Exchange and Outlook Web Access (OWA).  The report emails come with a .mhtml attachment which is blocked in owa.  With owa, even if you allow mhmtl file, owa automatically block your report. Is there anyone else that is experiencing this issue.  Is there a workaround?  A pdf attached to email.
