Are you getting a blank screen from the Microsoft Outlook app on your iPhone?
First, try clearing Microsoft Outlook from memory by double tapping the home button and swiping the screen shot of it up off the screen.
If that doesn't fix the problem, try power cycling your iPhone by holding down both the power and home buttons.
