This article provides descriptions of these interactions and best practices for how to work with these settings.
The effects of SharePoint settings on groups and teams
SharePoint setting
Description
Effect on Microsoft 365 groups and Teams
Recommendation
External sharing for organization and site
Determines if sites, files, and folders can be shared with people outside the organization.
If SharePoint, Microsoft 365 Groups, and Teams settings don't match, guests in the team may be blocked from accessing the site, or unexpected external access may occur.
When changing sharing settings, check Microsoft 365 Groups settings, Teams settings, and SharePoint site settings for group-connected team sites.
Allows or prevents content being shared with specified domains.
Microsoft 365 Groups and Teams don't recognize SharePoint allowlists or blocklists. Users from domains disallowed in SharePoint could gain access to SharePoint sites or content through a team.
Manage domain allowlists or blocklists for Microsoft Entra ID and SharePoint together, along with external access for meetings. Create an org-wide governance process for allowing and blocking domains.
Allow only users in specific security groups to share externally
Specifies security groups who can share SharePoint sites, folders, and files externally.
This setting doesn't prevent team owners from sharing teams externally. Team guests have access to the associated SharePoint site.
SharePoint site sharing settings
Determines who can share the site directly, outside of team membership. The team or site owner configures this setting.
This setting doesn't affect the team directly, but it can allow users to be added to a site and not have access to the team itself or other Teams resources
Consider using this setting to limit sharing of the site directly and manage site access through the team.
Let users create sites from the SharePoint start page and OneDrive
Specifies if users can create new SharePoint sites.
If this setting is turned off, users can still create group-connected team sites by creating a team.

Recommendation
Naming policies
Specifies Microsoft 365 group name prefixes and suffixes, and blocked words for group creation
Policies are enforced for users creating teams.
Microsoft 365 Groups guest access
Specifies if people outside the organization can be added to Microsoft 365 groups.
If either the Microsoft 365 Groups or Teams guest sharing settings are off, the team can't be shared with guests.
When changing guest sharing settings, check the settings for Teams, Microsoft 365 Groups, and the SharePoint site associated with the team.
Work with external users in Teams and the access controls from different places, including Microsoft Entra ID, Microsoft 365, Teams, and SharePoint admin centers.
Demonstrate skills to plan, deploy, configure, and manage Microsoft Teams to focus on efficient and effective collaboration and communication in a Microsoft 365 environment.
