Office Mobile 6.1 is an upgrade to Office Mobile on Windows Mobile. The new upgrade supports the new Office 2007 file formats. Microsoft Office 2007 introduced new Open XML-based file formats for Office applications. These new file formats reduce file size, improve security and reliability, and enhance integration with external sources.

To allow Windows Mobile users to work with Office documents created in the Open XML formats, Microsoft has developed an upgrade for Word Mobile, Excel Mobile, and PowerPoint Mobile applications. This upgrade to the Office Mobile applications allows viewing and editing of Word documents and Excel workbooks and viewing of PowerPoint slideshows created by using Microsoft Office 2007.

The Office Mobile application suite includes Microsoft Office Word Mobile, Excel Mobile, and Microsoft Office PowerPoint Mobile for Windows Mobile 6 powered devices, helping users manage and review documents. Microsoft Office Mobile includes support for rich reviewing and minor editing capabilities as well as support for rights-managed documents.

Note: This free upgrade works only for Windows Mobile powered devices that have an earlier version of Office Mobile. If your Windows Mobile powered device does not have Office Mobile applications, this upgrade will not work for you. You can purchase the full version of Office Mobile 6.1 online.
