It has been an exciting journey for all of them on the Microsoft Outlook team since launching Outlook apps for iOS and Android in January. As I said then, Microsoft’s goal is to bring a true Outlook email experience to every mobile platform. Today Microsoft shared that almost 30 million people are active users of Outlook on their smartphones and tablets. Roughly one in five of those are connecting more than one account, and Microsoft hears time and again from customers that they’re using Outlook regularly—both in and out of the office—to the tune of 1.2 billion sessions per month. These numbers show what they’ve known for some time—despite reports to the contrary—email is a key communications channel across all parts of our life, and there is growing demand for a mobile email experience that helps to effectively manage those conversations. Microsoft made terrific progress over the last nine months, but they are just getting started.

To help them continue to accelerate this momentum, Microsoft asked their new friends from Sunrise for some help. Over the past few months, they put their design expertise and fresh thinking to work on helping Microsoft deliver a more beautiful and improved experience. For Outlook users on iOS, this will be rolling out beginning today. Users on Android can expect to see updates beginning in early November. Of course, Outlook comes pre-installed in Windows 10 Mobile. Stay tuned to learn more about Outlook when Windows 10 Mobile arrives on devices.

A fresh new look for Outlook for iOS

Outlook for iOS receives a clean, refined new look that puts your email, calendar, people and files front and center. Throughout the app, Microsoft focused on improving the small but important details that add up to making Outlook the best designed, most powerful mobile email app available. Microsoft tweaked UI elements by adding visual cues to help you see and process information more quickly at a glance. Microsoft also improved navigation around the app and made key features more prominent—so you can do more with fewer taps. When getting work done on the go, it’s these little time savers that count.

For example, the message list on Outlook now clearly calls out event invitations. The “event” icon makes it easy to identify events at a glance, by showing the details of the proposed event with a clear action to RSVP right from your inbox. In addition, the “flag” and “attachment” icons are more prominently displayed on the right side of the message list, mirroring what Outlook users are used to on Windows. And when you’re scrolling down on your message list while triaging email, pressing the “Mail” navigation button pops you back to the top of your inbox.

When composing a new message, the attachment options are simplified and easier to access. Both File and Photo attachments are now available in one click.

The “Calendar” navigation icon now shows today’s date, while the “Today” button moves dynamically as you scroll through your calendar to help you visualize how far away from today you are. The day picker grays out days in the past, making it quick and easy to find the current day of the week or month. Drag down the day picker to show a full month view.

When viewing event details, Outlook provides a cleaner, clearer representation of information. All the core details (date, duration, location) are grouped at the top, while attendees now have green, gray and red icons that represent their responses to your invitation.

Outlook for Android gets a makeover

We want Outlook to feel like a natural part of Android. By deeply leveraging Material design and its common interface elements, Microsoft is making it easy to get started and become familiar with Outlook.

With this consistent design, Outlook for Android feels more cohesive. You’ll see right away as you open the app, with their redesigned header, message list and compose experiences. Contact images appear to the left of your emails, making it easy to see who emailed you. Clearer and more prominent icons help you identify read versus unread emails, pick out event invitations and quickly see emails that include attachments.

Bringing the best of Sunrise to Outlook

The Sunrise team is now officially a part of the broader Outlook product team, bringing a fresh approach to calendaring and combining it with Microsoft’s deep expertise in both email and calendar. Better Outlook calendaring gives you more ability to manage your personal and professional life from a single, powerful app. Over the coming months, you’ll see richer calendar experiences come to Outlook from Sunrise—including Interesting Calendars and connections to your favorite apps and services. You will also see improvements to Outlook’s ability to create meetings while on the go and handle meetings across time zones. All of this means Outlook will eventually replace the current Sunrise app. Microsoft will leave Sunrise in market until its features are fully integrated into Outlook, the exact timing of which Microsoft will communicate in advance.

We continue to work to deliver amazing improvements in Outlook every single week. Microsoft needs your feedback to help continue to make Outlook even better!
