Microsoft's Outlook app for iOS offers a handful of useful ways to organize your inbox and puts your calendar, contacts, and cloud storage one tap away.
Nicely organized: As you'd hope, Outlook does a nice job of displaying mail, with sender and message snippets displayed along with the subject line. Your mail is organized by thread, but you can turn off the conversation view to see your mail appear separately. Four tabs along the bottom take you to your mail, calendar, attachments, and contacts.
Focused Inbox: Outlook organizes your inbox around emails it considers the most important in what Microsoft calls a Focused inbox. Tap the Other tab to see a traditional view of your email organized by date. You can also filter messages by unread, flagged, or with attachments.
Calendar events: The app can also coordinate calendar events across different calendaring platforms, displaying them in one view.
Cloud storage: The app has hooks into Microsoft and non-Microsoft cloud servers, letting you attach files from OneDrive, Dropbox, and Box.
Lacks Outook.com features: Some of the useful features found in the Web version of Outlook are missing in the mobile edition, including access to Google Drive and the ability to connect to your Facebook account.
Outlook for iOS is a well-organized mail app that offers easy access to your contacts and connected calendars. If you are looking for a replacement for Google's Gmail app, or if you're frustrated by how Inbox organizes your messages, Outlook may be what you need.
