The following environment is required to use the OneDrive for Business connector:
- Microsoft SharePoint Online or Office 365
Legacy authentication must be enabled for crawl user accounts.
To enable legacy authentication, go to the Azure portal or contact your Azure Active Directory administrator.
The connector supports the Password hash synchronization (PHS) method for enabling hybrid identity only. Use any other type (such as pass-through authentication or Federation) at your own risk. Unless you created your SharePoint Online account before January 2020, two-factor authentication is enabled for the account by default. You must disable two-factor authentication.
