Child connectors

After you save the suite, set up SharePoint and OneDrive. Each uses its own app's client ID and certificate credentials. The tenant ID comes from the Microsoft 365 parent.

If a connector's setup shows inherited credentials instead of editable fields, keep the existing shared app and manage its credentials on Microsoft 365. You don't need to recreate working connections.

SharePoint

Index SharePoint sites, pages, document libraries, files, and lists.

OneDrive

Index personal drives and shared files from OneDrive.
