Summary: Microsoft 365 Groups enhance collaboration and information sharing. Admins can manage permissions easily, but data loss remains a concern. Groups are subject to a 30-day soft-delete retention policy, allowing restoration. Admins can manually restore deleted groups via the Office 365 Admin Center. Backing up Office 365 data, including Groups, is essential, with tools like Kernel Office 365 Backup and Restore ensuring secure data preservation. The tool simplifies backup, offering filters and migration options, enabling admin control and data security.

Microsoft 365 continually enhances productivity and collaboration. A significant innovation in team collaboration is Microsoft 365 Groups, enabling seamless information sharing among team members. It empowers collaborative tasks like email communication, document creation, spreadsheet collaboration, project planning, contact management, and scheduling meetings.

The Administrator does not require to add permissions to each member since they get all the permissions once they are added to the Group.

The Group feature in Microsoft 365 serves as the central hub for information sharing among colleagues. It’s available in plans including Exchange Server and SharePoint Online. Administrators can create, add members, and manage permissions. Team members collaborate on projects and documents, resolving queries. Admins must safeguard Group data by saving Office 365 emails to their desktops.

If Office 365 Groups are accidentally deleted, there’s no need to panic. Microsoft employs a “soft-delete” policy, ensuring the Groups aren’t permanently erased, and you can easily restore them.

NOTE – What is the retention policy for Microsoft Groups?

Data within a group isn’t promptly deleted. Instead, it’s retained for 30 days by default, even after group deletion. This 30-day period is termed a “soft delete,” offering an opportunity for restoration. However, once this grace period expires, the group is permanently and irrevocably deleted.

An administrator can use the retention policies and restore the following content:

  • Complete Team information
  • Entire Planner details
  • SMTP address of the group
  • SharePoint sites and files
  • Exchange Server message, contacts, and calendar
  • Complete Azure Active Directory (AD)
