How to Troubleshoot Microsoft Lists Form and Multiline Field Bugs

Product: Microsoft Lists
Device & OS: not provided
Scenario: Attempting to view, edit, or submit data through forms that contain multiline fields in Microsoft Lists.
Observed behavior: Forms display only the header and Submit button. Multiline fields fail to render, and the browser console shows warnings regarding deprecated features, third-party cookies, preloading, or duplicate icon registrations.

Before you start

Before escalating the issue, try clearing your browser cache or accessing Microsoft Lists in an incognito or private window to rule out temporary local browser conflicts.

Solution 1Recommended

Escalate to Your Microsoft 365 Administrator

Because this is a server-side rendering or code-level bug within Microsoft Lists, diagnostic logs must be collected and investigated by Microsoft's development support team.

Core functional bugs in Microsoft 365 cloud services generally cannot be fixed through local client troubleshooting. Your organization's IT admin has the necessary permissions to open a formal support ticket with Microsoft.

Identify your Microsoft 365 Administrator

Locate the IT administrator or the person who assigned your Microsoft 365 account. If you are unsure, check your organization's internal IT helpdesk directory.

Document the console warnings

Press F12 on your keyboard to open the browser Developer Tools. Navigate to the 'Console' tab and take screenshots of any red errors or warnings about cookies and preloading to share with your admin.

Request a Service Request creation

Ask your administrator to log into the Microsoft 365 admin center, navigate to the 'Support' section, and open a new service request detailing the multiline field bug.

Admin Support Access: Only users with an Administrator role in your Microsoft 365 tenant can access the admin center to request development support.

Frequently Asked Questions

Why does my Microsoft Lists form only display the header and Submit button?

This typically occurs due to a backend rendering bug or JavaScript conflicts involving multiline fields. The Microsoft development team needs to review diagnostic logs to deploy a fix for your tenant.

How do I find out who my Microsoft 365 admin is?

Your admin is usually the person who set up your work email or the IT department in your organization. If you are a standard user, you can also reach out to your HR or IT helpdesk for this information.

Can I fix the multiline field bug by changing my browser settings?

While clearing your cache or enabling third-party cookies might resolve some specific console warnings, core form rendering bugs in Microsoft Lists generally require a server-side fix directly from Microsoft Support.
