 Once a site get's connected to a Microsoft 365 group then the Microsoft 365 group's external sharing settings play a role: by default external sharing of Microsoft 365 groups is enabled, which implies that you can for example use the Azure AD management UI and share the created group with an external. From a SharePoint perspective however the external sharing settings defined on the SharePoint site overrule the settings on the Microsoft 365 group.
 
 > [!IMPORTANT]
-> If your site is configured to not allow external users then that setting will be respected, even if the Microsoft 365 group does allow external sharing.
