Its paying customers increased almost 40% year over year in June 2021 to 169,000. Microsoft also offers Yammer, an enterprise social network software package that is a more direct competitor with Meta's Workplace. Yammer's usage had doubled year over year, with "tens of millions of monthly active users" as of August 2021. Workplace has integrations with Microsoft's Office 365, SharePoint, Azure Active Directory, OneDrive and Teams, but not with Yammer, Singh told CNBC. "I would say we're best-in-class around community, connection, people first and serving all employees," he said. "Teams is arguably best-in-class around productivity, so this is really two best-in-class products coming together to solve an employee-experience problem."
