The files you save on your SharePoint server are accessible to everyone with site permission. However, you may want to share certain files with people who don’t use SharePoint regularly. That’s where the external sharing feature comes into play. To activate the setting, you have to be a SharePoint manager in Microsoft 365. Site managers don't have the authority to enable or disable external sharing. Here’s how to do it: 1. Log in to the SharePoint admin center web page. 2. Navigate to the column on the left-hand side. Choose a site from the list. 3. Click on the circle next to the sharing option you want to enable. The options available are determined on the company level. If you disable external sharing on a particular site, any links you shared on it will no longer function.
