Microsoft launched Office 2010, and this includes a version for Windows phone. This is a new tool to share documents and ensure they look as expected.
This application allows users to edit Word, Excel, and PowerPoint files, and there is also a version of OneNote.
In addition, this suite of applications now include Mobile Workspace SharePoint 2010. This lets users browse the document library, open the file to view or edit, and save them directly back to the server.
