Outlook 2011 HTML email received as plain text on some addresses only

I'm running Outlook 2011 14.3.6 (130613).

Sending messages is fine. 

Receiving most messages is fine, however there is a particular email address that comes from the office to my laptop and most of the time (not always), the message is received in plain text instead of HTML.

All other messages from the same office domain are received as HTML.

Any assistance would be appreciated..
