How to Handle Microsoft Graph Folder Copy 403 Errors and Partial Success
Question details
Developers need a way to track completed versus failed items when a Microsoft Graph folder copy operation encounters a 403 error due to partial file permissions.

- Product
- Microsoft Graph
- Device & OS
- not provided
- Scenario
- Executing a bulk folder copy operation via Microsoft Graph API where some underlying files lack necessary user permissions.
- Observed behavior
- The folder copy operation fails entirely with a generic 403 Forbidden error, providing no visibility into which items were copied and which items failed.
Ensure you have access to your API error logs and verify the specific account permissions for the files inside the target directory before attempting to debug the 403 response.
Submit a Feature Request to the Microsoft Feedback Portal
Since Microsoft Graph currently lacks built-in partial success reporting for folder copies, submitting detailed feedback is the official way to advocate for this feature.
Microsoft Graph's bulk copy endpoints do not natively support a 'continueOnError' parameter or return a 207 Multi-Status response out of the box. To improve the API, developers are encouraged to report these use cases directly to the product team.
Navigate to the official Microsoft Feedback Portal specifically designated for Microsoft Graph API integrations.
Log in using your Microsoft developer or organizational account to ensure your feedback is properly tracked and attributed.
Create a new post detailing the need for 'per-item results' or a '207 Multi-Status-style' response during bulk folder copy operations.
Specifically mention adding an optional 'continueOnError=true' parameter so applications can audit partial successes and retry only the failed items.

Implement Item-by-Item Copying as a Workaround
Instead of relying on the bulk folder copy endpoint, you can iterate through items individually to isolate failures and capture specific 403 errors.

Frequently Asked Questions
Why does my Microsoft Graph folder copy return a 403 Forbidden error?
A 403 error during a bulk folder copy typically means the authenticated user lacks the necessary read or write permissions for at least one specific file or subfolder contained within the target directory.
Can I use a continueOnError parameter in Microsoft Graph for folder copies?
Currently, the Microsoft Graph API does not natively support a 'continueOnError' parameter for bulk folder copy operations. If a single item fails due to permissions, the entire operation halts.
What is a 207 Multi-Status response in APIs?
A 207 Multi-Status response is an HTTP status code that allows a server to return multiple independent success or failure codes for different items within a single bulk request. Developers frequently request this feature for Microsoft Graph to easily identify partial successes.
