Problem with editing files in Onedrive in a SharePoint library linked to in Onedrive

Potential Cause: Conditional Access Policies for Unmanaged Devices

Microsoft has implemented conditional access policies that can restrict or limit access to SharePoint and OneDrive content from unmanaged devices (devices not compliant with your organization's policies or not joined to your domain). These policies can affect users' ability to edit or upload files when accessing SharePoint libraries through OneDrive, especially if the device is considered unmanaged. In such cases, users might encounter "Access Denied" errors when attempting to modify files via OneDrive, while still retaining full access through the SharePoint web interface.

Steps you can try to Resolve the Issue…

Review Conditional Access Policies:

• As an administrator, examine the conditional access policies configured in your Microsoft Entra (formerly Azure Active Directory) admin center.
• Check if there are policies that restrict access from unmanaged devices to SharePoint and OneDrive resources.​

Adjust Access Settings:

• If restrictions are in place, consider modifying the policies to allow limited access from unmanaged devices or to permit editing capabilities as needed.
• Use PowerShell commands like Set-SPOTenant or Set-SPOSite to adjust site-level settings. Microsoft Learn​

Verify User Permissions:

• Ensure that users have the appropriate permissions on the SharePoint library.
• Use the "Check Permissions" feature in SharePoint to confirm that users have edit rights. Microsoft Learn​

Check for Unique Permissions or Inheritance Issues:

• Inspect the SharePoint library for any unique permissions or broken inheritance that might be causing access issues.
• Resetting permissions to inherit from the parent site can sometimes resolve unexpected access problems. SharePoint Diary​

Test Access from Managed Devices:

• Determine if the issue persists when accessing the SharePoint library from a managed device (one that complies with your organization's policies).
• If access is successful from managed devices, it further indicates that the problem is related to device compliance settings.​
