On October 21, 2010, Microsoft debuted Office Mobile 2010 with the release of Windows Phone 7. In Windows Phone, users can access and edit documents directly off of their SkyDrive or Office 365 accounts in a dedicated Office hub. The Office Hub, which is preinstalled into the operating system, contains Word, PowerPoint and Excel. The operating system also includes OneNote, although not as a part of the Office Hub. Lync is not included, but can be downloaded as standalone app from the Windows Phone Store free of charge.
