Microsoft 365 Groups are a fundamental tool in the Microsoft ecosystem, designed to bring together teams and resources for seamless collaboration. Whether you’re a business or education provider, understanding how to leverage Microsoft 365 Groups can transform the way your organisation communicates, collaborates, and manages projects. But with multiple group types and specific capabilities, navigating Microsoft 365 Groups can initially feel daunting. Here’s a comprehensive breakdown to clarify how you can harness the power of Microsoft 365 Groups, tailored for businesses and educational institutions.

Understanding Different Group Types in Microsoft 365
Microsoft 365 Groups are central to the platform’s collaborative framework. When you create a Microsoft 365 Group, you gain a “single identity” across the entire ecosystem, which integrates seamlessly with services like Microsoft Teams, Planner, Outlook, and SharePoint. This single identity is automatically linked to various resources, streamlining permission management and making it easier for teams to collaborate.
With Microsoft 365 Groups, each group has an associated shared inbox, calendar, document library, OneNote notebook, and a SharePoint site, allowing team members to collaborate efficiently. You can also link various Planner plans to the group.
Other Group Types:
Distribution Groups: Useful for sending emails to a group of recipients. Unlike Microsoft 365 Groups, they don’t support collaboration tools such as document libraries or calendars.
Security Groups: Designed to grant access to resources (like SharePoint sites) rather than provide a collaborative space.
Mail-enabled Security Groups: These provide the same resource access as security groups but also have an email address, allowing members to receive group emails.
Shared Mailboxes: Shared mailboxes offer a shared inbox that users can send and receive emails from. These don’t have additional collaboration tools, unlike Microsoft 365 Groups.
Core Components and Capabilities of Microsoft 365 Groups
Creating a Microsoft 365 Group automatically generates a range of collaboration resources:

Shared Inbox: A dedicated email address where members can communicate and receive messages, both internally and from external contacts if configured.
Shared Calendar: Ideal for coordinating group events, meetings, and deadlines.
SharePoint Document Library: Provides centralised storage for files, making file sharing and collaboration easy.
OneNote Notebook: A shared notebook for capturing ideas, notes, and research.
Planner: A task management tool for organising and tracking project tasks.
SharePoint Team Site: A space for additional resources, links, and files related to the group’s objectives.
By centralising these resources, Microsoft 365 Groups make it easy for teams to access everything they need without needing to manually assign permissions.

Managing Group Membership and Permissions
Microsoft 365 Groups come with built-in roles to simplify membership and access management:
Group Owners: Group owners manage membership, control settings, and can update the group’s name, description, and picture. They have admin-level permissions and are responsible for moderating the group.
Group Members: Members have access to the shared resources and collaboration tools within the group but can’t alter group settings.
If you’re used to SharePoint, owners function similarly to site collection admins, while members have permissions comparable to site members.
Governance and Security: Policies and Controls
To prevent accidental or uncontrolled group creation and to enhance governance, Microsoft 365 offers several configuration options:
Creation Permissions: By default, any user can create a Microsoft 365 Group, which can lead to an overabundance of groups. You can restrict group creation rights to specific users or groups to avoid this.
Naming Policies: Admins can enforce naming conventions for groups, ensuring consistent naming for easier management and compliance.
Expiration Policies: These help manage the lifecycle of groups by setting expiration dates for inactive groups, reducing clutter in the organisations tenant.
External Access Control: By default, guests in Microsoft 365 Groups have full access to group content. Admins can restrict external access to specific domains to protect sensitive information.
Microsoft allow for up to 50,000 external users in a tenant at no extra cost, making collaboration with external partners more flexible and scalable.
Collaboration Beyond Organisational Boundaries: External Access
One of the standout features of Microsoft 365 Groups is its ease of sharing with external users. With policies to manage domain restrictions and access levels, Microsoft 365 Groups allow businesses and educational institutions to collaborate securely with external parties.
Group Privacy Options and Flexibility
When creating a Microsoft 365 Group, you can choose between:
Private Groups: Membership is controlled by the group owners, and access requests must be approved.
Public Groups: Open to anyone within the organisation, making it easy to join without needing approval.
Admins can set the organisation’s default privacy setting for new groups or change the privacy of an existing group as needed. Additionally, each group can support up to 100 owners and over 1,000 members, though individual users are limited to creating a maximum of 250 groups.

Dynamic Membership and Automation with Entra ID
To streamline membership management, Microsoft 365 Groups support dynamic groups that automatically adjust membership based on Entra ID (Azure Active Directory) attributes, such as department or job title. This feature requires Entra ID Premium P1 licensing but reduces administrative burden by ensuring group membership is always up-to-date.
Data Retention and Recovery
Microsoft 365 Groups include built-in safeguards to prevent data loss:
Group Recovery: Deleted groups can be restored within 30 days, allowing admins to retrieve groups if they were removed accidentally.
Document Retention: Files deleted from the group’s SharePoint library are retained in the SharePoint recycle bin for 93 days, giving users ample time to recover important content.
Requirements for Using Microsoft 365 Groups
To use the full range of Microsoft 365 Group features, organisations need a subscription with Exchange Online and SharePoint Online, available in the Business Essentials, Business Premium, and Enterprise E1, E3, and E5 plans. For those with only an Exchange subscription, group functionality is limited to the shared inbox and calendar, without access to the document library or Planner.
