Microsoft Teams Basics [The Ultimate Guide In 2020]

Today I’m going to discuss about Microsoft Teams basics. The strategies in this post help you grow from scratch.

What is Microsoft Teams?

  • MS teams app Is a chat-based workspace in Office 365 that makes it easy to have persistent and threaded conversations, host meetings, share files, collaborate on documents, and get work done with teams across the organization.
  • Microsoft Teams lets you work in a natural, conversational way – with everything you need in one place – available anytime, on any device.

Office 365 Groups

An Office 365 Group is an object in Azure Active Directory with a list of members and a loose coupling to the following workloads.

  • Office 365 Groups let you select a set of people that you wish to collaborate with and easily set up a collection of resources/workloads for those people to share.
  • Adding members to the O365 group automatically gives them the required permissions.
  • An O365 group is created automatically from any of these products:
  • The specific workloads that are created are depended on which product creates the O365 Group. For example, when you create a new plan in planner it will not create all the required workloads used by Teams.

What is created when you create a TEAM?

When you create a new Team, it automatically creates an Office 365 Group; a SharePoint teamsite and other workstreams.

Coexistence Modes

To aid the migration from Skype for Business to Microsoft Teams, Microsoft introduced coexistence modes. Each mode can be assigned to an individual user or at the tenant level.

  • Skype for Business with Teams Collaboration Only
    • Skype for Business remains unchanged with chat, calling, and meeting capabilities. Introduce Teams collaboration capabilities (teams and channels), access to files in Office 365, and applications.
  • Skype for Business with Teams Collaboration and Meetings
    • Identical to “Skype for Business with Teams Collaboration Only” with the addition of Teams meetings.
  • Islands Mode
    • Default org-wide setting.
    • Each of the client applications operates as a separate island. Skype for Business talks to Skype for Business, and Teams talks to Teams.
    • Users run both clients and can communicate natively in the client from which the communication was initiated. As such, there’s no need for interoperability in Islands mode.
  • Teams Only mode
    • An upgraded user can continue to communicate with other users who are still using Skype for Business however, an upgraded user can’t initiate a Skype for Business chat, call, or meeting.
