Last April, Microsoft was at 75 million daily active users. Microsoft officials have said the rapid growth of the product is in large part fueled by the need for remote work during the COVID-19 coronavirus pandemic.
Microsoft Corporate Vice President Jeff Teper tweeted the new Teams number today. The 145 million number was as of the end of March 2021, which was the end of the fiscal third quarter.
Teams is part of Microsoft's "Commercial cloud" category and also is part of its office commercial products and cloud services revenue category. Teams began as a group-chat platform but Microsoft has been turning it into an almost operating-system-like product over time by extending its capabilities and features.
Microsoft announced in February that it was adding more integrations between Teams and Dynamics 365 -- as well as others of its services. Today, Microsoft announced that Dynamics 365 revenue growth was up 45 percent over the previous year's quarter.
