The Microsoft Outlook mobile app (officially known as Outlook for Android and Outlook for iOS) is a mobile personal information manager (PIM) for Android and iOS devices.

The app provides unified communication functionality, as opposed to splitting email, calendar, and contact management functionality into multiple, focused apps the way Windows 10 Mobile's apps. Similar to its desktop counterpart, Outlook Mobile offers an aggregation of attachments and files stored on cloud storage platforms; a "focused inbox" highlights messages from frequent contacts, and calendar events, files, and locations can be embedded in messages without switching apps. The app supports a number of email platforms and services, including Microsoft 365, Exchange Online, Exchange Server, Outlook.com, third parties like G Suite among others.^[3]

First released in April 2014 by the venture capital-backed startup Acompli, the company was acquired by Microsoft in December 2014 for over US$200 million. On January 29, 2015, Acompli was re-branded as Outlook Mobile—sharing its name with Microsoft's desktop PIM Outlook and its Outlook.com email service.^[4] The following month, Microsoft acquired the mobile calendar app Sunrise Calendar; its key features were similarly subsumed by Outlook Mobile in September 2016.
