Fix Power BI OAuth Connection Errors with SharePoint Data Sources
Question details
The user is experiencing OAuth login errors in Power BI when attempting to create or maintain a connection to a SharePoint data source for scheduled dataset refreshes.
- Product
- Microsoft Power BI and SharePoint
- Device & OS
- not provided
- Scenario
- Configuring scheduled dataset refreshes in Power BI using SharePoint data.
- Observed behavior
- An OAuth login error is displayed, preventing the scheduled refresh from successfully connecting to the SharePoint data source.
Before troubleshooting, ensure you have the necessary administrator permissions for both your Power BI workspace and the SharePoint site, and verify that your Microsoft account login credentials are up to date.
Seek Support in Microsoft Fabric Power BI Forums
Leverage official Microsoft resources and community specialists to investigate cloud connection and OAuth compatibility issues.
Since OAuth errors involving SharePoint and Power BI are often tied to backend Microsoft cloud services, tenant settings, or service outages, the official Microsoft Fabric community is the best place for specialized assistance.
Collect the exact error message, data source type, and connection method. Ensure you omit any sensitive personal information such as passwords or exact tenant IDs.
Navigate to the Power BI forums on the Microsoft Fabric Community platform using your web browser.
Create a new post detailing your SharePoint connection issue and the specific OAuth error received during your scheduled refreshes.
Reconfigure Data Source Credentials
Updating or re-entering the OAuth credentials in Power BI can often clear expired authentication tokens and resolve the connection error.

Frequently Asked Questions
Why does Power BI show an OAuth error for SharePoint?
OAuth errors typically occur when authentication tokens expire, user account passwords change, or there are unexpected permission mismatches between the Power BI service and the SharePoint data source.
How can I safely share my error details on the Power BI forums?
When posting on public forums, include the error code, connection method, and data source type, but be sure to mask out sensitive information like passwords, client IDs, and personal email addresses.
Does refreshing a SharePoint dataset require special permissions?
Yes, the account used to configure the scheduled refresh in Power BI must have at least 'Read' access to the specific SharePoint site, list, or document library being queried.
Can I use basic authentication instead of OAuth2 for SharePoint in Power BI?
For cloud-based SharePoint Online connections, Microsoft strongly recommends and often requires OAuth2 for enhanced security; basic authentication is frequently blocked or unsupported by modern tenant policies.
