Cant share Microsoft form with anyone

Thank you for your response please consider the answers marked above as accepted and very useful

Good day Gareth, 

Thank you for providing the screenshots and details. 

Based on the interface shown in your screenshot, the form was created from a SharePoint List rather than as a standalone Microsoft Form. 

Forms created from a SharePoint List follow the permissions of the underlying SharePoint site and list. As a result, external users must sign in and have access to the list before they can open the form. This is why the Anyone can respond option isn't available and why external users are redirected to a sign in page. 

The Anyone setting in SharePoint controls sharing for SharePoint content such as files, folders and lists. The Microsoft Forms sharing settings apply only to standalone Microsoft Forms and don't make a SharePoint List form publicly accessible. 

Here are some options you may consider: 

Option 1: Create a standalone Microsoft Form (Recommended) 

If you want people outside your organization to submit responses without signing in: 

Go to Microsoft Form.  

Create a new Microsoft Form and recreate the questions from the current form. 

Select Collect responses > Choose Anyone can respond > Share the response link with external users. 

If you would like to receive an email whenever someone submits a response: 

Open the form > Select Settings > Under Response receipts, enable Get email notification of each response. 

Option 2: Save responses to the existing SharePoint List 

If you want responses stored in the current SharePoint List: 

Create the standalone Microsoft Form. 

Open Power Automate. 

Create an automated flow using: 

When a new response is submitted (Microsoft Forms) 

Get response details (Microsoft Forms) 

Create item (SharePoint) 

Map each form answer to the corresponding SharePoint List column. 

Save and test the flow. 

This allows external users to submit responses without signing in while keeping the SharePoint List accessible only to authorized users. 

Example:

Note: If you'd like to use this option, please let me know. I'd be happy to provide more detailed guidance. 

Option 3: Keep the current SharePoint List form 

If you continue using the existing form in SharePoint, external users must be granted access to the SharePoint site or list and will need to authenticate before they can submit responses. Anonymous public access isn't supported for SharePoint List forms. 

Additionally, since the current sharing link provides access to the list content, please review the sharing permissions and remove any links that grant broader access than intended by opening the SharePoint List > Selecting Share > Manage access > Deleting any unnecessary sharing links. 

If you have any questions or need further support, please don’t hesitate to reach out at any time. 

Thank you for your patience and understanding.
