March 12 is Microsoft's big day. This is the first anniversary of the launch of Microsoft Teams, Microsoft's office collaboration software. In a year, MTs has captured 200,000 corporate users in 181 markets. On that day, Microsoft also took advantage of the situation to launch a feature update notice. Microsoft Teams will integrate AI assistant Microsoft Xiaona. Users can easily call, attend meetings or add people to attend meetings by "communicating" with Xiaona. The move was interpreted by foreign media as Microsoft's big move in the competition with office collaboration software startup Slack. It's not new for big companies to hunt small companies, but it's amazing for foreign giants like Google and Facebook to hunt for a startup, including Microsoft. In fact, the same is true in the field of office collaboration software in China, although there is no big one.
