SharePoint permissions

Concept

How access to SharePoint sites and content is controlled: through a Microsoft 365 group or the SharePoint groups Owners, Members and Visitors, and through sharing links for single files and folders.

Description

SharePoint permissions decide who can open, edit or manage a site and its content. Microsoft Learn describes the model by site type. Team sites are by default connected to a Microsoft 365 group: the group owners become site owners and the group members become site members. Communication sites are not connected to a Microsoft 365 group and use the standard SharePoint groups Owners, Members and Visitors. For private and shared channel sites, permissions are managed in Teams.

On a team site, the three groups have the permission levels Full Control (Owners), Edit (Members) and Read (Visitors). A Microsoft 365 group has no view-only access, so people who should only read must be added directly to the Visitors group. Microsoft recommends managing permissions through the Microsoft 365 group or the team where possible, and advises against nested security groups because they can cause performance problems.

Permissions on a site, group or team give access to all content in it. To share a single file or folder, SharePoint offers sharing links of three types: Anyone, People in your organization and Specific people. A site can allow external sharing only if it is allowed at organization level first.
