Question details

Users need to resolve permission errors that prevent them from editing previously submitted Microsoft Forms responses.

How to Fix Microsoft Forms Cannot Edit Saved Responses (Error 707 & 6212)

Product: Microsoft Forms
Device & OS: not provided
Scenario: Respondents are trying to update or edit their previously saved responses in Microsoft Forms after the form owner has enabled respondent editing.
Observed behavior: The editing process fails, and the interface displays permission-related errors such as Code 707 or Code 6212, indicating missing required tokens or backend permissions.

Before you start

Ensure that the form owner has explicitly checked the 'Allow respondents to edit their responses' option in the form settings, as this feature must be active before troubleshooting backend errors.

Solution 1Recommended

Escalate to Microsoft Support with Tenant Logs

Since Error 707 and 6212 are often tied to tenant-specific backend token failures, your IT administrator must investigate and open a Microsoft 365 support ticket.

These specific permission errors rarely resolve on the client side. They indicate that the backend service cannot validate the authentication token required to modify the saved data.

Verify Service Health

Have your IT administrator log into the Microsoft 365 Admin Center, navigate to Health, and select Service health to check if there is an active incident affecting Microsoft Forms.

Gather Error Details

Collect the exact Form IDs, the dates of the affected responses, timestamps of the failed editing attempts, and the specific error codes displayed (e.g., Code 707 or Code 6212).

Generate HAR Logs

Ask an affected user to open Microsoft Forms in their browser, press F12 to open Developer Tools, go to the Network tab, and recreate the error. Right-click the network activity and select 'Save all as HAR with content'.

Open a Support Request

In the Microsoft 365 Admin Center, the administrator should navigate to Support > New service request and submit the collected details and HAR logs for the Microsoft engineering team to investigate.

Escalate to Microsoft Support with Tenant Logs

Tenant Specificity: Because this issue often lacks a global service health advisory, providing detailed logs from your specific tenant is crucial for a timely resolution.

Solution 2

Test Editing on a Newly Created Form

Determine if the permission error is isolated to specific legacy forms or if it affects all forms across your organization.

Frequently Asked Questions

What does Error Code 707 mean in Microsoft Forms?

Error Code 707 typically indicates a backend permission or authentication token failure. It means the system cannot verify your authorization to modify a previously saved response, even if the form owner enabled the editing feature.

Can I fix Error 6212 without contacting my IT administrator?

Usually, no. Error 6212 is a tenant-level backend issue. It requires your organization's Microsoft 365 administrator to open a support ticket with Microsoft so their development team can investigate the missing permissions.

How do I collect HAR logs for Microsoft Support?

Open your web browser's Developer Tools (usually by pressing F12), navigate to the Network tab, and check 'Preserve log'. Reproduce the editing error in Microsoft Forms, then right-click the network activity list and select 'Export HAR' or 'Save all as HAR'.
