The European Commission opened a formal antitrust investigation into the conduct of Microsoft Inc. to assess whether it breached competition law by tying or bundling Microsoft Teams to its Office 365 and Microsoft 365 productivity suites. This investigation was subsequent to a complaint filed by Slack, a workspace messaging App Company, alleging that by tying its Microsoft Team product with Office Microsoft was forcing the installation of Teams, blocking its removal and hiding the true cost to enterprise customers.
