Microsoft Teams is a rapidly expanding and increasingly important part of the Office 365 family. It aims to bring together the conference call capability of Skype for Business with the team collaboration capability of SharePoint and the document storage of OneDrive.
In the modern office many teams are spread geographically. Members may be working from home, from other offices and perhaps in different time zones. Teams aims to make it possible to share information either by messages, documents,voice/video calls or host online meetings.
