ActiveSync on Android shows raw message

I have been able to get my Android phone configured to use the Exchange option for configuring a connection to my MIAB but when I open each mail I see a raw view of the message, including the headers and body… When I reconfigure the mail to use IMAP it works as expected…

Has anyone seen this behavior?

I have been playing around with the configuration and have still been unable to determine why my Android phone gets emails in their raw message format. Removing the ActiveSync config and switching to IMAP resolves the issue but then I lose the contacts synchronization…

Nobody else is having this issue?

I haven’t noticed this issue on my Galaxy S4.
