External sharing links will be displayed as they are detected.
The time it takes to crawl for external sharing links depends on a number of factors, including tenant size, the number of items in a library, and the number of links in your environment.
The fastest that an external sharing link will be displayed is 24 hours. You can view external sharing links from the Manage page and team and group details.
Tip: Create a governance plan to manage external sharing links using ShareGate's automation and collaboration features. For more information, see External sharing management features overview.
