Outlook.com: Some Emails on Android using Outlook.com app only show Text format

I am using the official Microsoft Outlook.com app on my Samsung Galaxy S4 and some emails are only showing the text version of that email, instead of HTML.  I thought I had fixed it by uninstalling and reinstalling the Outlook.com app, but it's back now.  I see some text and then links to the information, with no pictures.  What I should see is the Display as HTML button or just the HTML page, but it's not working like it should.  Is this a known issue?  I see the other posts about some sort of connection error, but I'm getting the emails, just not in the correct format.
