Believe it or not, Microsoft's Outlook app for Android and iOS hasn't let you add or edit contacts -- you've had to turn to your PC or the web for that. At last, though, common sense prevails. As of now, you can add and edit your Outlook.com and Office 365 contacts through the iOS app (Android and Google contacts are "coming soon"). You can go to the People section to add details yourself, or add people from events, messages and your company directory. Also, Outlook lets you save those contacts to your phone's native list so that you won't be surprised when they give you a call.
