To uninstall any app in Android, simply go into your SETTINGS and APPLICATION MANAGER

Here you will find the apps that you have installed (downloaded) - tap the app and choose "uninstall"

Go into the app draw and hold the icon for the app and drag it up to the trash can on the top and release. It will uninstall the app.

The best method, to avoid old files being left behind:

Settings > Apps > Select Outlook (or whatever) > Force stop > Clear cache > Clear data > Uninstall
