Back in June, Microsoft announced that they are bringing contact management experience to Outlook Mobile apps. This feature is now available on Outlook Android app. Users can add to and edit contacts on Outlook.com and Office365 accounts. Support for Google contacts is also coming with the future update.
To create a new contact in Outlook, simply go to the People tab and tap the + sign. You can edit their already saved information by opening the contact and tapping the Edit button. Outlook fully synchronizes with the Contacts app in your phone. So, users can add new contacts or make changes in either the Outlook app or by using the built-in Contacts app on Android. Changes made will sync back to corresponding email service. To enable this sync on Android devices, go to your account within Settings and tap Sync Contacts.
Download the app here from Play Store.
