Microsoft 365 lets you share content with people from outside your organization using their external sharing features.
External sharing links
When a user in your organization shares content with a person outside of your Microsoft environment, a sharing link to the item is sent to that person. For more details about how to create sharing links, see the Microsoft article Share SharePoint files or folders.
During routine crawls, ShareGate detects content in your environment that has an external sharing link. You can then see which teams and groups have external sharing links from the Manage page and team and group details.
ShareGate can detect sharing links to content such as:
- Audio files
- Image and video files
Note: ShareGate does not detect content shared through direct access within SharePoint Online. Only content with sharing links is detected.
