Summary: Microsoft rolls out Office Mobile suite for Android phones for Office 365 subscribers. By Mary Jo Foley for All About Microsoft |July 31, 2013 -- 12:53 GMT (05:53 PDT) Just over a month after making available a mobile version of its Office suite for iPhone users, Microsoft is doing the same with an Android version of Office Mobile. And just like it did with the iPhone version, Microsoft is tying the Android version of Office Mobile to Office 365. Users who want to use the mobile versions of Word, Excel and PowerPoint on their Android phones will need to have an Office 365 subscription, such as Office 365 Home Premium, Office 365 ProPlus or these other SKUs to get them. Office Mobile for Android phones (known officially as "Office Mobile for Office 365 Subscribers") is launching initially in the U.S. on July 31 and can be downloaded from the Google Play Store for free. The plan is to make it available in 33 languages and 117 markets "over the next several weeks." The Office Mobile for iPhone and Android suites are both like the Office Mobile suite that Microsoft preloads on Windows Phone, meaning they are optimized for the editing, viewing and creation of Word and Excel documents. (Microsoft already has offered OneNote for Android phones since February 2012.) Unlike Office Mobile for iPhone, Office Mobile for Android phones does not include an option to purchase an Office 365 subscription from within the app, however. Office Mobile for Android phones only has a sign in option. Office 365 subscribers are authorized install Office Mobile on up to five iPhones and/or Android phones. (Office Mobile on Windows Phones don't count against that total.) Office 365 University subscribers can install Office Mobile on up to two non-Windows Phones. Microsoft is still widely believed to be developing versions of its core Office apps that would be customized to work on iPads and Android tablets. As with the iPhone and Android phone versions, these Office tablet apps would likely be tethered to an Office 365 subscription, tipsters have hinted. One internal Microsoft roadmap I saw indicated that Office for iOS and Android might not arrive until the fall of 2014. But it was unclear from that roadmap if this was a reference to Office for iPhones and Android phones or Office for iPad and Android tablets. If the fall 2014 date was simply a reference to the new Office Mobile suites, Microsoft may have decided to push these cross-platform versions of Office for mobile devices out more quickly than planned not so long ago.
