SharePoint Lists: the new experience arrives in December

Microsoft is refreshing the user experience of SharePoint Lists. The rollout starts in mid-December 2026 and is expected to complete by late December. For most users, it is a facelift. If you have customized the command bar of your lists with JSON, you should check beforehand whether your buttons will still be where they belong.

The basis is Message Center post MC1530610 “SharePoint Lists: Refreshed user experience” from 29 October 2026.

What changes

Microsoft lists five points:

• Command bar: reorganized
• Navigation: clearer breadcrumb navigation in lists with folders
• Views: selecting and creating views becomes more prominent
• View settings: consolidated in one place
• Filters: active filters appear as visible “filter pills”

That makes sense. The visible filters in particular solve an old problem: users wonder why items are missing because a filter is still active somewhere.

According to Microsoft, no action is required, the new experience arrives automatically. The post mentions no admin switch, no way back and no date for Targeted Release.

What does not break and what you should check

First the good news. Microsoft writes: “Existing SPFx extensions, column formatting, and view formatting are not expected to be affected beyond the command bar placement behavior.” So your column and view formatting are expected to stay as they are.

The catch is in the command bar. If you customize it with JSON, you use commandBarProps. It lets you rename or hide commands, or place them with position and sectionType. Exactly this placement may shift with the reorganized command bar. Microsoft itself recommends reviewing it.

⚠️ Attention
Hidden commands disappear not only from the command bar but also from the context menu. If something shifts after the rollout, users notice it in two places.

Commands from an SPFx ListView Command Set also appear in the command bar. Microsoft says the extensions themselves are not affected. Where their buttons end up, however, depends on the same placement logic.

What Microsoft does not do well here

Testing is hardly possible. The post only gives the GA date. It does not mention a Targeted Release where you could check things in advance. “Test now” is easier said than done.

The documentation lags behind. The Learn page on command bar formatting lists several renamed keys, for example versionHistory to versionHistoryCommand. Microsoft itself marks the new key as “currently not working”. According to the page, the JSON schema has not been updated yet. The page does not address the new experience at all.

The scope is unclear. The post talks about “SharePoint Lists”. Whether the Lists app, lists in Teams or document libraries are affected as well is not stated.

The timing. From mid to late December, many IT teams are in a change freeze or on vacation. Coming back after Christmas, they find a new experience and the first tickets.

What you can do now

1. Find your customizations: Which lists use commandBarProps in their view formatting? Which sites have ListView Command Sets? That list is your checklist for December.
2. Flag critical lists: Lists where a misplaced button has real consequences, such as approvals, orders or tickets.
3. Collect training material: Guides, screenshots and intranet help pages that show the old command bar. That is where the real effort lies.
4. Inform key users: A short note before Christmas: new experience, filters are now visible, commands may be in a different place.
5. Use the first rollout day: As soon as the new experience reaches you, go through the list from step 1.

What stays

The new experience is a sensible refresh. Visible filters and clearer navigation help everyone who works with lists every day. There is no reason to panic, according to Microsoft formatting and extensions stay intact. What is annoying are the circumstances: no test ring, documentation marked “currently not working” and a rollout during the holidays.

☕ Espresso Moment: When the portafilters get rearranged, the coffee tastes the same. You just reach for the wrong shelf at first.
