EU antitrust regulators ramp up Microsoft scrutiny over Teams integration into Office 365

Microsoft is likely to face an EU antitrust investigation as regulators intensify their scrutiny into its practices in a case triggered by Salesforce.com’s workspace messaging app Slack, people familiar with the matter said on Thursday.

Last year, Slack complained to the European Commission, saying that Microsoft has unfairly integrated its workplace chat and video app Teams into its Office product. Microsoft introduced Teams in 2017, seeking a slice of the fast-growing and lucrative workplace collaboration market.

Slack urged the EU competition enforcer to order the US software giant to separate Teams from the Office Suit and sell it separately at fair commercial prices.
