Microsoft announced in June that it would be purchasing professional social network LinkedIn in a cash deal worth $26.2 billion.
The purchase will further cement Microsoft into the world of social media after previous deals with Facebook and the acquisition of Yammer in 2012.
A deal this large requires approval from regulators around the world and today Microsoft received its final approval.
Other agencies in the United States, Canada, Brazil, and South Africa have already reviewed and cleared the deal.
By passing the European Commission, Microsoft is set finalize the acquisition.
The long delay in approval stems from the European Court's requirement that Microsoft preserve competition among other social networks.
