Some users unable to access microsoft form but others can

Dear @Wendy Comeau,

Thank you for posting your question in the Microsoft Q&A forum. Based on your description, I understand that some recipients are unable to access the form even though it’s set to “Anyone with the link can respond."

To better asssistance, could you please confirm:

• Were any changes made to the form’s settings after the link was first shared?
• Do the affected users share a common browser, device type, or network (e.g., corporate firewall, VPN)?
• Are you able to reproduce the issue yourself using a private/incognito browser window?

In the meantime, I recommend as below:

• Reopen the form settings and toggle the sharing option off and back to “Anyone with the link can respond,” then generate a fresh link.
• Share the new link with affected users and ask them to open it in a different browser or in a private/incognito window.
• If the issue persists, consider duplicating the form and sharing the new version. It often resolves hidden configuration glitches.

Please understand that our initial response does not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution.

I truly appreciate your patience and understanding. If you have any further questions or need further clarification, please feel free to reach out. I'm looking forward to hearing from you. 

Thank you for your cooperation.

It sounds like the issue you're experiencing with Microsoft Forms could be related to the settings and permissions associated with the form. Here are a few things to check:

1. Form Settings: Ensure that the form is indeed set to allow responses from "Anyone with the link can respond." Sometimes, settings can be inadvertently changed.
2. Microsoft Account Requirement: While it is true that users do not need an Office 365 account to respond to a form, if the form is configured to restrict access based on certain criteria, some users may be prompted to sign in. Verify that there are no restrictions set that might require users to have a Microsoft account.
3. Browser and Device Compatibility: Sometimes, specific browsers or devices may have issues accessing forms. Ensure that users are trying to access the form using updated browsers and devices.
4. Network Restrictions: Some users might be on networks that have restrictions preventing access to certain Microsoft services. It might be worth checking if they can access the form from a different network.
5. Error Messages: The error message "Sorry, an error happened" could indicate a temporary issue with the service or a configuration problem. You might want to check the Microsoft service status to see if there are any ongoing issues.

If the problem persists after checking these items, consider reaching out to Microsoft support for further assistance.
