Question details

The OneDrive search endpoint in Microsoft Graph is returning an empty array despite successful authentication and file downloads via MSAL.

How to Fix Microsoft Graph OneDrive Search Returning No Results on iOS

Product: Microsoft Graph API
Device & OS: iOS
Scenario: Querying the OneDrive search endpoint via Microsoft Graph API in an iOS application or Graph Explorer to locate specific user files.
Observed behavior: The API call successfully authenticates but the search endpoint returns an empty array with no results, both in the custom iOS app and Graph Explorer.

Before you start

Verify your application's API scopes in Microsoft Entra ID to ensure 'Files.Read' or 'Files.Read.All' permissions are properly consented to by the user.

Solution 1Recommended

Escalate the Issue to the Microsoft Graph Support Community

Because the search endpoint is failing across both custom iOS apps and Graph Explorer, this indicates a potential backend service anomaly that requires specialized Microsoft investigation.

Microsoft Graph search endpoint issues are often tied to backend indexing delays, unannounced endpoint changes, or tenant-specific service degradations. These fall outside the scope of general troubleshooting.

Posting detailed logs to the dedicated Microsoft Q&A forum allows Graph engineers to investigate the specific correlation IDs and trace the search failures.

Gather your API request details

Copy the exact HTTP GET request URL you are using, the headers (excluding the Bearer token), and the exact JSON response containing the empty array.

Document the account and permission scopes

Note down whether you are querying a personal Microsoft Account (MSA) or an Enterprise Azure AD account, along with the delegated permissions granted to your MSAL app.

Post in the Microsoft Graph Forum

Navigate to the Microsoft Q&A community for Microsoft Graph. Create a new thread including your request format, response details, account type, and the exact date the search behavior started failing.

Escalate the Issue to the Microsoft Graph Support Community

Include Request IDs: Always include the 'request-id' and 'date' headers from the API response so Microsoft specialists can look up the specific failed transaction in their telemetry logs.

Solution 2

Verify API Call Syntax and Path Validation

Ensure the API endpoint syntax strictly follows Microsoft Graph documentation, as malformed paths can silently return empty arrays instead of error codes.

Frequently Asked Questions

What details are required when reporting a Microsoft Graph bug?

You should include your exact request format, the granted MSAL permission scopes, the account type (MSA or Azure AD), the response details (including 'request-id'), and the date the issue first occurred.

Why does Graph Explorer return empty search results but file downloads work?

File downloads directly target an item ID, whereas the search endpoint relies on backend indexing services. If the index is delayed, corrupted, or experiencing an outage, search queries will return empty arrays while direct file access remains functional.

Are there known limitations for OneDrive search via Microsoft Graph on iOS?

There are no iOS-specific search limitations in the Graph API itself. If the failure happens in both the iOS app and Graph Explorer on the web, it points to a server-side issue or account configuration rather than an iOS development bug.
