Microsoft Office 2010 codenamed Office 14

Microsoft Office 2010, codenamed Office 14, is a productivity suite for Microsoft Windows, and is the successor to Microsoft Office 2007 for Microsoft Windows. Office 2010 includes extended file compatibility, user interface updates, and a refined user experience. It will be available for Windows XP SP3 (32-bit), Windows Vista SP1, and Windows 7. With the introduction of Office 2010, a 64-bit version of Office is available for the first time, although only for Windows Vista SP1, Windows Server 2008 SP1, Windows 7 and Windows Server 2008 R2. Neither the 32-bit edition of Office 2010 nor the 64-bit edition is supported on Windows XP Professional x64 Edition.
On April 15, 2010, Microsoft announced that Office 2010 had been released to manufacturing, with those Volume Licensing customers who have Software Assurance being able to download the software from April 27. Availability in retail stores in the US is to be from June.
Office 2010 marks the debut of free online versions of Word, Excel, PowerPoint, and OneNote, which will work in popular web browsers (Internet Explorer, Mozilla Firefox, Google Chrome, and Apple Safari). A new edition of Office, Office Starter 2010, will replace the current low-end home productivity software, Microsoft Works.
Microsoft's update to its mobile productivity suite, Office Mobile 2010, will also be released for Windows Phones running Windows Mobile 6.5 and Windows Phone 7. In Office 2010, every application has the Ribbon, including OneNote 2010, Publisher 2010, InfoPath 2010, SharePoint Workspace 2010 (the new name for Microsoft Office Groove 2007) and the new Office Web Apps.
A new feature in Microsoft Office 2010 is the Social Connector. This allows users to write emails while keeping track of their family, friends and colleagues by viewing status updates and past communication history with the individual. When users view their emails a name, picture, and title will be available for the person they are contacting. Upcoming appointments can also be viewed with this new feature and users can request friends. The Social Connector doesn't work with Office x64 bit versions and Microsoft suggests to use the 32 bit products on their official forums and support. Sync features for Windows Mobile phones like email, contacts and other integration will also not work with x64 versions of Office 2010. There is no information if the final releases coming up in a fews days will patch this feature as to date a lot of features and integrations are rendered in the x64 version of Office 2010.
