The SharePoint Left Sidebar Changed: What the New Microsoft 365 Experience Means

TL;DR

Microsoft is refreshing the SharePoint experience in Microsoft 365, and one of the most noticeable changes is the new left sidebar. Instead of SharePoint feeling like only a place to open sites and documents, the new navigation organizes the experience around what users are trying to do: Discover information, Publish communication, Build business solutions, and move between SharePoint and OneDrive more easily.

For users, this may make SharePoint easier to understand. For SharePoint admins, intranet owners, and Microsoft 365 teams, it is also a reminder to review site naming, permissions, content ownership, publishing standards, and governance. A cleaner interface helps, but it does not fix stale content, confusing site structures, or poor permissions by itself.

If you opened SharePoint recently and noticed that the left side of the screen looks different, you are not imagining it.

Microsoft has been rolling out a refreshed SharePoint experience, and one of the most visible changes is the new left-side app bar. Instead of the older SharePoint navigation experience, users may now see a cleaner sidebar with entry points such as:

• Discover
• Publish
• Build
• OneDrive

At first glance, this may look like a small user interface change. The main visual difference is that SharePoint now feels more like a Microsoft 365 workspace with a persistent left rail. Instead of users only landing on a start page and then relying on search, bookmarks, or site navigation, the sidebar gives them clearer destinations based on intent: finding content, publishing content, building solutions, or opening personal files in OneDrive.

But for SharePoint admins, intranet owners, content authors, and Microsoft 365 teams, this update says something bigger about where SharePoint is going.

SharePoint is no longer being positioned only as a place where sites and documents live. Microsoft is reshaping it into a more guided workspace for finding content, publishing communication, building business solutions, and using AI-assisted experiences across Microsoft 365.

What changed in the SharePoint left sidebar?

The biggest change is that SharePoint now has a more structured side app bar.

Microsoft describes the new SharePoint experience as being centered around three major activities:

1. Discover information
2. Publish communication
3. Build solutions

This is a major shift from the older experience where users often had to rely on site navigation, bookmarks, search, or the Microsoft 365 app launcher to move around.

The new sidebar gives users clearer starting points depending on what they are trying to do.

Discover: SharePoint as a smarter starting point

The Discover area is designed to help users find and return to relevant SharePoint content faster.

Instead of making users remember every site name, bookmark every page, or search manually every time, Discover brings together relevant sites, news, files, recent activity, and people-related signals.

For everyday users, this can make SharePoint feel less like a maze.

For admins and intranet teams, this matters because discoverability has always been one of the biggest SharePoint challenges.

A company may have hundreds or thousands of sites, but users often only know the few links they already have saved. Discover is Microsoft’s attempt to make SharePoint feel more personalized and more useful as a front door to organizational knowledge.

Publish: A clearer home for pages, news, and campaigns

The Publish area is focused on SharePoint communication.

This is where pages, news posts, templates, recent content, analytics, and Microsoft Viva Amplify-related publishing experiences start to come together.

This is important because many organizations use SharePoint as their intranet platform, but content publishing can still feel scattered. Authors may need to jump between different sites, page libraries, drafts, news posts, campaign tools, and analytics reports.

The Publish experience helps bring that work into one more obvious place.

For intranet owners, this could make content governance easier. It gives authors a stronger starting point and helps them focus on the full content lifecycle:

• Create the page or news post
• Reuse templates
• Return to drafts
• Review recent content
• Check performance and analytics
• Support broader communication campaigns

This is a good reminder that modern SharePoint is not just about storing content. It is also about delivering the right message to the right audience.

Build: SharePoint as a business solution platform

The Build area may be the most interesting change for SharePoint developers, power users, and admins.

Build is Microsoft’s new entry point for creating and managing SharePoint-based solutions such as:

• Sites
• Lists
• Document libraries
• Agents
• Business process experiences

This matters because many business solutions inside Microsoft 365 still start with SharePoint.

A department may need an issue tracker, onboarding checklist, document approval library, policy acknowledgement process, asset register, or internal request list. In many cases, SharePoint lists, libraries, pages, and permissions are still the foundation.

The new Build experience makes that role more visible.

It also signals that Microsoft wants users to think of SharePoint as more than an intranet or file storage layer. SharePoint is still a platform for building lightweight business applications, especially when combined with Power Platform, Microsoft Lists, SPFx, Teams, and Copilot-related capabilities.

Why OneDrive appears in the SharePoint sidebar

Seeing OneDrive in the SharePoint sidebar may feel surprising at first, but it makes sense.

SharePoint and OneDrive are tightly connected behind the scenes. OneDrive is generally used for personal work files, while SharePoint is used for shared team, department, and organizational content.

By placing OneDrive closer to SharePoint, Microsoft is reinforcing the relationship between personal files and shared organizational content.

For users, this may reduce confusion when moving between “my files” and “team files.”

For admins, it is another reminder that governance cannot treat OneDrive and SharePoint as completely separate worlds. Sharing settings, retention, sensitivity labels, external access, and lifecycle policies often need to be reviewed together.

Why this update matters for SharePoint admins

This left sidebar change is not only a cosmetic update.

It affects how users enter SharePoint, how they discover information, and how they start creating content or solutions.

For SharePoint admins, this means a few things should be reviewed:

1. Site naming matters even more

If Discover surfaces sites and content more intelligently, messy site names become more obvious.

Sites called “Project Team,” “Test Site,” “New Site,” or “Department Documents” are not helpful when users are trying to identify the right place to work.

Admins should review naming conventions and make sure important sites have clear titles, descriptions, ownership, and branding.

2. Content ownership needs to be cleaned up

A smarter discovery experience is only useful when the content being surfaced is still relevant.

If old news posts, abandoned sites, outdated pages, or orphaned files keep appearing, users may lose trust in the experience.

This is a good time to review:

• Site owners
• Page owners
• News publishing ownership
• Site lifecycle policies
• Archive or deletion processes
• Stale content reports

3. Permissions still matter

A better interface does not fix poor permissions.

If users are discovering content across SharePoint more easily, admins need to make sure permissions are intentional.

This is especially important for sites with broken inheritance, direct user permissions, external users, and old SharePoint groups that have not been reviewed in months.

The experience may be new, but the classic SharePoint governance problems are still there.

4. Content authors may need guidance

The Publish experience may be helpful, but authors still need standards.

Organizations should define when to use:

• A page vs. a news post
• A department site vs. a communication site
• A SharePoint page vs. Viva Amplify campaign
• A template vs. a custom layout
• A promoted news item vs. a normal update

Without publishing guidance, the new tools can still create inconsistent content.

5. Build access should be governed

Build makes solution creation more visible, but that also means organizations should be clear about who can create what.

Admins should review settings for:

• Self-service site creation
• Microsoft Lists usage
• SharePoint site templates
• External sharing defaults
• Power Platform environment strategy
• Copilot and agent availability
• Owner accountability

The goal should not be to block business users from building. The goal should be to help them build in a way that is secure, supportable, and aligned with governance.

What this means for intranet owners

For intranet owners, this update is a good opportunity to revisit the employee experience.

The new SharePoint direction is focused on helping users quickly answer questions like:

• Where do I find the latest company news?
• What sites matter to me?
• What documents did I recently work on?
• Where do I create a new page or news post?
• How do I get back to content I was editing?
• Where do I start building something new?

If your intranet already has clear information architecture, strong content ownership, and useful navigation, the new SharePoint experience can support that.

If your intranet is messy, outdated, or hard to search, the new sidebar may expose those problems faster.

My take: this is a small visual change with a bigger message

The left sidebar may look like a simple design update, but I think it represents a bigger shift in SharePoint.

Microsoft is organizing SharePoint around user intent:

• Discover when you need to find knowledge
• Publish when you need to communicate
• Build when you need to create a solution
• OneDrive when you need your personal work files

That is a cleaner mental model than expecting every user to understand sites, hubs, pages, libraries, lists, app bars, and navigation structures right away.

For admins and developers, the important takeaway is this:

SharePoint is becoming more user-friendly on the surface, but governance, permissions, architecture, and lifecycle management are still what make the experience successful.

A new sidebar can help users move faster.

But it cannot fix unclear ownership, stale content, poor permissions, or weak information architecture.

That part is still on us.

Practical checklist for Microsoft 365 teams

If your tenant already shows the new SharePoint sidebar, here are a few things I would review:

• Check how important sites appear in Discover
• Review site names, logos, descriptions, and owners
• Clean up outdated pages and news posts
• Confirm publishing standards for intranet authors
• Review external sharing and broken permission inheritance
• Confirm who can create sites, lists, libraries, and agents
• Update internal SharePoint training screenshots
• Notify help desk teams so they recognize the new interface
• Review whether business users understand the difference between SharePoint and OneDrive
• Use this change as a reason to revisit SharePoint governance

Final thoughts

The new SharePoint left sidebar is one of those updates that users will notice immediately.

Some will think it is just a design refresh. Others may be confused at first because familiar navigation patterns changed.

But from an admin and intranet perspective, this is a good moment to step back and ask a bigger question:

Is our SharePoint environment ready for a more discovery-driven, publishing-focused, and AI-assisted Microsoft 365 experience?

Because the sidebar changed, but the real work is still making sure users can find the right content, trust what they find, and build solutions without creating long-term governance problems.
