The move follows on from Microsoft's release last year of the Outlook Social Connector plug-in to synchronise social networking feeds with Outlook contact, according to Mashable.
Microsoft is reportedly also planning to release the plug-in for Outlook 2003 and 2007 to bring Facebook, MySpace, LinkedIn, and Windows Live Messenger to millions of inboxes worldwide
Facebook's integration in Outlook Social Connector will enable users to see Facebook profile photos, of contacts, pull news feeds of contacts into their inboxes, and see activities such as status updates.
The combination with LinkedIn, MySpace, Windows Live Messenger, and Outlook data will give users a detailed history of interactions with contacts.
The integration of information will also provide an overview of their activities and interests, which could be used as a powerful marketing tool.
But for now, the Facebook integration enables Outlook users only to pull data from Facebook, but not push information other than make friend requests.
Outlook will also only pull data from e-mails connected to Facebook accounts, so if a business e-mail is not linked to a user's Facebook, that data stream will not appear in Outlook Social Connector.
