EU probes Microsoft over Teams-tied office bundles

The EU targets the technology giant with software like Teams in its portfolio. It is a cloud-based tool for communication and organizing work. It offers messaging, calls, video conferences, and file-sharing features.

Business application software providers, including Microsoft, are increasingly distributing this software as a cloud computing service (SaaS). Cloud computing allows new market players to offer SaaS solutions and customers to use various programs from different providers.

However, as reported by the EC, Microsoft's business model combines many types of software in one offer. When Teams was launched, Microsoft included it in its widely used cloud packages for business clients: Office 365 and Microsoft 365.

The EC is concerned that, since April 2019, Microsoft has tied Teams to its core productivity SaaS applications, thus limiting competition in the communication and collaboration products market and defending its market position against other providers.

In the EC's opinion, Microsoft might have given Teams a distributional advantage without giving customers a choice of whether they want access to Teams when subscribing to its productivity SaaS applications.

The EC believes this advantage may have been further deepened by interoperability constraints between Teams competitors and Microsoft's offerings. Such behaviour could have prevented Teams' rivals from competing and, consequently, innovating to the detriment of customers.

After the EC initiated proceedings in July 2023, Microsoft changed how Teams is distributed. However, the EC has preliminarily determined that these changes are insufficient to address its concerns and has initiated a new proceeding.

EU law prohibits the abuse of a dominant position. If the EC finds sufficient evidence of a violation, it can impose a fine of up to 10 percent of the company's annual turnover in the global market.
