The Outlook app separates your mail into two tabs—Focused and Other.

Important emails appear in your Focused Inbox, while the rest remain out of the way in the Other tab.

Outlook's calendar functionality is pretty standard; you can view the entire month at a glance or focus on a specific week, with your appointments appearing at the bottom of the screen for any highlighted day.

Outlook seamlessly it syncs with your cloud storage services. You can log in to your OneDrive, Google Drive, Dropbox, Box and iCloud accounts, and once you do, you can view a list of all of your recent files available on each account, making it supereasy to send attachments.

The app's People tab pulls in contacts from all of your connected email accounts. Contacts are sorted by how recently you've contacted them, and you can quickly email any contact on your list right from the People tab.
