Fix Microsoft Forms Photo Upload Access Denied in Power Automate
Question details
Email recipients encounter an 'Access Denied' error when attempting to open photo or file links generated by Microsoft Forms and sent via Power Automate.
- Product
- Microsoft Forms and Power Automate
- Device & OS
- not provided
- Scenario
- Users submit a Microsoft Form containing file or photo uploads, which triggers a Power Automate flow that sends the upload links to specified email recipients.
- Observed behavior
- Recipients click the file links in their email but are blocked by an 'Access Denied' screen because the files inherit restrictive default permissions from OneDrive or SharePoint.
Ensure you have owner permissions for the Microsoft Form and the associated OneDrive or SharePoint document library where the uploaded files are stored.
Modify Folder Sharing Permissions in OneDrive or SharePoint
Manually grant the intended recipients access to the folder where Microsoft Forms stores uploaded files.
By default, files uploaded to a personal Microsoft Form are stored in the creator's OneDrive, while group forms store files in SharePoint. These locations restrict access to the file owner unless explicitly shared.
Navigate to your OneDrive or SharePoint site. Go to 'Apps', then 'Microsoft Forms', and open the folder matching your form's name.
Select the 'Question' folder containing the uploaded files, click the three-dot menu (ellipsis), and choose 'Manage Access'.
Click 'Share' or 'Grant Access'. Enter the email addresses of the users who receive the Power Automate emails, or change the link settings to 'People in your organization with the link can view'.
Attach the File Directly via Power Automate
Bypass link permission issues entirely by extracting the file content and attaching it directly to the automated email.

Frequently Asked Questions
Why do files uploaded to Microsoft Forms inherit restricted permissions?
By default, files uploaded by users to Microsoft Forms are saved securely to the form creator's OneDrive or the group's SharePoint site. This default security measure ensures privacy, meaning automatic emails containing links to these files do not automatically grant viewing rights to the email recipients.
Where are Microsoft Forms file uploads stored?
If you created a personal form, the uploaded files are stored in your OneDrive for Business under 'Apps > Microsoft Forms > [Form Name]'. If it is a group form, they are stored in the default document library of the associated SharePoint site.
Can my organization administrator fix this globally?
Yes. If your flow relies on organization-wide sharing but external sharing or 'Anyone' links are disabled, your Microsoft 365 administrator can adjust the sharing settings in the SharePoint or OneDrive admin center to allow broader access.
