Professional social network LinkedIn is showing a little Microsoft love today. In conjunction with the announcement of the beta of Microsoft's Office 2010 at its Professional Developer Conference, LinkedIn and Microsoft have partnered to offer an add-on that integrates much of your LinkedIn contact information with your Outlook contacts. The add-on to Outlook will provide professional and social context to any Outlook users everyday email experience. When you received an email from a contact who happens to be a member of LinkedIn, Outlook will show a collapsible pane that will show information on what the contact's latest activity is on Linkedin.
