We’re thrilled to announce that Outlook for iOS and Android is now powered by the Microsoft Cloud for Office 365 commercial users! This means that all your data is now fully delivered through Microsoft services that provide a strong commitment to security, privacy and compliance. There has never been a better time to make your move to Outlook and join the 42-million active users already enjoying the only mobile email and calendar app designed to work with the best features of Office 365.
No matter which industry you’re in—from banking to the public sector—we’re committed to help you address your legal, regulatory and compliance needs while still providing you with the best mobile experience.
Here’s a peek into our recent changes.
A look into Outlook’s new architecture
Outlook for iOS and Android now supports Exchange Online mailboxes natively, which means that none of the data of your mailboxes is cached outside of Office 365. Data simply stays in its current Exchange Online mailbox and is protected by TLS-secured connections end to end between Office 365 and the Outlook apps.
To make this work, Outlook uses a stateless protocol translator component that is built and run in Azure. This component serves to route data and translate commands (Outlook Device API to REST and vice versa) between Outlook and Exchange Online, but it doesn’t cache any user data.
This new architecture also improves how Outlook reports Device IDs to Exchange Online, to help admins manage mobile email access through Outlook. Outlook now individually reports a unique Device ID for each device connecting to Exchange Online. Previously, Outlook connections from iOS or Android were reported at the user level. The mobile device details reported, along with the Device ID are also more robust, as Outlook now reports Device Name and Device OS back to Exchange. You can read more about these changes and how they impact Device Access rules on TechNet.
Why move your team to Outlook for iOS, Android and Windows 10 Mobile?
On top of the recent improvements to our architecture, we think there are lots of reasons why the Outlook apps for iOS, Android and Windows 10 Mobile are a great fit for our Office 365 customers.
The best of mobile and the best of Office 365, combined in one app—Called “the best mobile email app, no matter what phone you’re using” by Wired, Outlook is helping millions of users manage their inboxes and calendars on the go, with innovative, unique features like Focused Inbox, customizable swipe gestures and integrated calendar apps.
More importantly, Outlook is the only email app especially designed to support the full Office 365 experience, providing your teams with a coherent experience from desktop to mobile. Over the past year alone, we’ve provided rich integration with Office, OneDrive for Business and Skype for Business, support for IRM protected email, Automatic Replies settings and multi-factor authentication, to name just a few.
And we’re only getting started.
A reduced load for your IT Help Desk—Getting all your teams on Outlook means that your IT Help Desk only has to support and manage one mobile email solution moving forward. No more dealing with dozens of built-in email apps across a range of devices. You can start drafting your training and onboarding materials for Outlook on mobile—they’re the only ones you’ll ever need.
Also, Outlook provides end-user in-app support for basic tasks from Microsoft trained agents, so you don’t have to do it. Our persistent chat support means your Help Desk can offload the simpler how-to work (like signing in, adding accounts and general use of the app) and focus on more business-critical activities.
A range of options to protect your data—Outlook provides several options to secure and protect email on mobile devices. Office 365 and Outlook include built-in controls for core security needs—including enforcing PIN lock, multi-factor authentication and the ability to remotely wipe lost or stolen devices. Outlook also is tightly integrated with the advanced capabilities of Microsoft Enterprise Mobility + Security (EMS) to make sure that your team’s data is safe.
A few capabilities of EMS include:
