I too am having a problem with Outlook. It's probably Outlook App related (as opposed to Samsung) but still it's annoying. One moment, I'll open up my email, and it works just fine. The next, I'll open up the email, and all i get is the "sender" and "time" header.... the body of the email won't open until I shut down all applications on my phone, and restart the app. Annoying. Would like a fix soon. And to Original poster, I found that "clicking" on the left most screen button (don't know what it's called... the "recently used apps" button, and then closing down all existing apps, and then reopening Outlook will restore email operation on my phone. Hope it works for you.
