How to Troubleshoot Slow or Failing SharePoint File Sharing
Product
SharePoint
Device & OS
not provided
Scenario
Sharing files across multiple devices, files, and accounts within a Microsoft 365 organization.
Observed behavior
Sharing operations take several minutes to complete or fail entirely, indicating a potential backend service or tenant-level issue rather than a localized error.
Before you start

Verify whether the sharing issue is isolated to a single file or affects multiple users in your organization, and ensure you have contact with your Microsoft 365 administrator.

Solution 1Recommended

Review Service Health and Submit a Support Request

Use this solution when sharing issues persist across multiple devices and accounts, which strongly suggests a Microsoft 365 service or tenant-level problem.

When SharePoint sharing fails globally across your organization, it cannot be fixed by clearing local browser caches or restarting devices. These symptoms point to backend server degradation or configuration issues that require administrative intervention.

1
Access the Microsoft 365 Admin Center

Ask your Microsoft 365 administrator to log in to the Microsoft 365 admin center using their global or support admin credentials.

2
Check Service Health

Navigate to the 'Health' section in the left sidebar and select 'Service health'. Look for any active advisories or incidents related to SharePoint Online or OneDrive for Business.

3
Create a New Service Request

If no known outages are reported but the issue persists, go to the 'Support' tab and click on 'New service request' to open a ticket with Microsoft.

4
Provide Detailed Diagnostic Information

In the support ticket, include specific details such as the affected SharePoint site URLs, user email addresses, exact timestamps of the failures, and any error codes displayed on screen.

Frequently Asked Questions

Why does SharePoint take so long to generate a sharing link?

Slow link generation is often caused by backend service degradation on Microsoft's servers, temporary throttling due to high traffic, or tenant-level misconfigurations. Checking the Service health dashboard can confirm if this is a known issue.

Can I fix tenant-level SharePoint issues on my local computer?

No. Tenant-level issues affect the backend infrastructure of your entire organization. Troubleshooting steps like clearing your browser cache, restarting your PC, or reinstalling apps will not resolve these centralized server problems.

What details should I provide to my IT admin when sharing fails?

To help your IT administrator and Microsoft Support investigate, provide the exact URL of the affected file, the exact time the error occurred, the email addresses involved, and screenshots of any specific error messages.
