Microsoft announced today that it acquired Acompli, an email client for Android and iOS, in an effort to own more productivity apps on each mobile platform:

Acompli also wrote about the acquisition news while discussing support for various file services:

The acquisition follows Microsoft’s announcement last month that Office for iOS no longer requires an Office 365 subscription for editing files and the debut of dedicated Office for iPhone apps including Word, PowerPoint, and Excel. Microsoft also integrated Office support with Dropbox as part of a new partnership between the two companies.

According to Re/code, Microsoft spent more than $200 million to buy up the email app although neither company disclosed that amount.
