  2. Shared Calendar: A shared calendar allows group members to schedule and manage events and meetings.
  3. Document Library: Each group gets a document library in SharePoint for storing and collaborating on files.
  4. OneNote Notebook: A shared OneNote notebook is provided for taking notes and organizing information.
  5. Planner: Microsoft Planner is integrated with groups to help with task management and project planning.
  6. Microsoft Teams: Groups can be integrated with Microsoft Teams for real-time communication and collaboration.

How Microsoft 365 Groups Can Be Used

Collaboration and Communication

Microsoft 365 Groups enhance collaboration by providing a centralized space where team members can communicate, share documents, and manage tasks. This is particularly useful for project-based teams that need to coordinate efforts and stay aligned.

A marketing team can create a Microsoft 365 Group to manage their campaigns. They can use the shared mailbox for email communication, the document library for storing marketing materials, and Planner to track campaign tasks.

Groups can be used for project management by leveraging tools like Planner and the shared calendar. This helps teams stay organized and ensures that everyone is aware of deadlines and responsibilities.

A software development team can create a group for each project. They can use the shared calendar to schedule milestones, Planner to assign tasks, and the document library to store project documentation.

Differences Between Microsoft 365 Groups and Legacy Distribution and Security Groups

Distribution Groups

Key Differences

  • Purpose: Security groups are used for access management, while Microsoft 365 Groups focus on collaboration and communication.
  • Resources: Microsoft 365 Groups come with shared resources like mailboxes and document libraries, while security groups do not.
  • Management: Security groups are managed through Active Directory, whereas Microsoft 365 Groups are managed through the Microsoft 365 Admin Center.
