In their FY21 Q3 results, Microsoft announced that Teams now boasts 145 million daily active users. That’s a growth of 30 million over the last six months. Office 365 now has nearly 300 million paid seats. A paid seat is different to an active user, but Microsoft loves to mix up its data so that people believe what Microsoft wants them to think. In any case, the numbers are impressive.
