Microsoft "Teams" set sales discontinued, policy changed worldwide. European regulators are keeping a close eye on the lock-in business conducted by giant IT companies.

Microsoft previously sold ``Teams'' in addition to ``Microsoft 365,'' which includes the word processing software ``Word'' and the spreadsheet software ``Excel.'' Last year, the European Commission began investigating the company for possible violations of EU competition law, which falls under antitrust law. It is possible to continue with the existing contracts.
