Microsoft has integrated Facebook into its Outlook e-mail system, technology news website Mashable has reported today.
Outlook users will now be able to view their e-mail contact's Facebook profile photos, news feeds, status updates, pictures and wall posts from Outlook - though they will have to log into the site to post replies to Facebook messages.
The move follows the release of Microsoft's Outlook Social Connector plug-in last year, designed to sync Outlook in with social networking sites.
According to Rick Armbrust, strategic partner manager at Facebook, both companies have worked together closely to improve the social experience of Outlook.
Although Facebook integration has been built directly into Outlook 2010, Outlook 2003 and 2007 users can still download Connector as a plug-in.
Microsoft's Office 2010 product manager Chris Adams said: "The Outlook Social Connector and providers from partners such as Facebook makes it easy and convenient for busy people to stay in touch with the people they care about."
