Microsoft hit with EU antitrust charge over Teams app, risks hefty fine

Microsoft faces a hefty antitrust fine after the European Commission on Tuesday accused it of illegally linking its chat and video app Teams with its Office product, giving it an unfair advantage over rivals such as Slack.

Eleven years after Microsoft’s last EU fine, the EU competition watchdog’s latest action was triggered by a 2020 complaint from rival workspace messaging app Slack, owned by Salesforce.

Reuters first reported in April that the EU was preparing the charges.
