Microsoft Teams

Microsoft Teams is one of Microsoft's newest services and a direct competitive service to Slack. It is a real-time and persistent collaborative work space that's easy to quickly set up and integrates instant messaging, meeting, notes capabilities, and file management, as well as the ability to easily integrate in other Microsoft and third-party apps. This service gives teams of people, internal and external, the ability to have their own work space and collaborate on a single source of truth.

In organizations with purely cloud implementations of Office 365, users with Skype for Business and Microsoft Teams will eventually be migrated to Microsoft Teams only. Microsoft Teams is included with the Business Essentials, Business Premium, E1, E3, and E5 plans. If you have an E5 plan, you may also get a phone number assigned to you from this service and have the ability to dial out and receive calls via this application.
