Product
Microsoft Lists
Device & OS
Multiple (Windows, macOS, iOS)

Attempting to add new items, edit existing records, or attach files in Microsoft Lists using a desktop web browser.
Observed behavior

Before you start

Ensure your browser is updated to the latest version and try clearing your browser cache and cookies before proceeding with alternative workarounds.

Solution 1Recommended

Use Firefox or Desktop-Site Mode on Mobile

Since the issue primarily affects Chromium-based browsers and Safari, using Firefox or forcing desktop mode on mobile can serve as a temporary workaround to add or edit items.

This web application bug seems to impact major browsers differently. While Edge, Chrome, and Safari are entirely unresponsive, Firefox may allow intermittent functionality.

Using a mobile browser's built-in feature to request the desktop version of a site can also force the 'Add New Item' control to render correctly.

1
Try Mozilla Firefox

Download and open Mozilla Firefox, log into your Microsoft 365 account, and attempt to access and edit your Microsoft Lists.

2
Open mobile web browser

On your smartphone or tablet, launch your preferred web browser (such as Safari or Chrome) and navigate to the Microsoft Lists web app.

3
Request desktop site

Tap the browser menu (usually a generic settings icon or 'aA' in the address bar) and select 'Request Desktop Site' to reveal and use the Add New Item controls.

Frequently Asked Questions

Why are the buttons in Microsoft Lists suddenly unresponsive?

This is typically caused by a backend web application update or bug rolled out by Microsoft, affecting script execution and button functionality across desktop browsers like Edge, Chrome, and Safari.

Can I still access and edit my Lists data while the web app is broken?

Yes, you can use the official Microsoft Lists iOS or Android mobile applications, which use different backend frameworks and continue to function normally despite the web application issues.

Does clearing the browser cache fix the Microsoft Lists button issue?

While clearing the cache resolves many basic browser issues, a widespread button unresponsiveness across multiple different browsers is typically a server-side bug requiring Microsoft to release an official patch.
