Overview
SharePoint provides site owners with the option to enable or disable site access requests. Disabling access requests will eliminate site requests received via email and help prevent site administrators from inadvertently approving access requests. Some site administrators may find these site access requests helpful, informing them of potential audiences who have a legitimate need for their site’s content but were overlooked when the site permissions were first created.
Someone who has access to your site URL or has been given access to a document or document library within a site can potentially see navigation and file path links to or within your site or hub. If this happens, the user will be presented with one of two automated responses based on the Access Request Settings selected for each site.
Note for Hub Site Owners: You will need to apply the access request setting of choice in the Hub site and check for consistency across each associated site. Changing this setting for the Hub site does not auto-update your associated sites.
