The European Commission is conducting a market test to assess Microsoft's new concessions regarding its Teams and Office products, aiming to resolve an antitrust probe initiated by a Slack complaint. Microsoft unbundled Teams from Office 365 in the EU but offered further concessions, including a seven-year separation and improved interoperability. The market test, involving feedback from rivals and customers, precedes a final decision on whether to impose fines, potentially reaching 10% of Microsoft's global annual turnover. Salesforce, the owner of Slack, will scrutinize the offer, while other investigations against Microsoft are ongoing in the EU and UK.
