Fix Microsoft Planner Cannot Scroll Across Buckets Issue
Question details
Users are unable to scroll horizontally to view or access all buckets in Microsoft Planner.

- Product
- Microsoft Planner
- Device & OS
- not provided
- Scenario
- Trying to view, manage, or access newly created task buckets in a Microsoft Planner board.
- Observed behavior
- The horizontal scrollbar is missing or non-functional. Users can only see hidden buckets by zooming out the browser window, but the buckets become inaccessible again once the zoom level is restored.
Before proceeding, try accessing your Planner board using a different web browser or clearing your current browser's cache to rule out local rendering glitches.
Report the Issue via Microsoft 365 Admin Center
Since this is a known bug affecting multiple tenants, opening an official support ticket is the most effective way to flag it for a backend resolution.
This horizontal scrolling problem has been reported by multiple Microsoft Planner users. Because it is a server-side interface bug, local troubleshooting is limited, and it requires Microsoft's engineering team to deploy a fix.
Reach out to your organization's Microsoft 365 administrator or dedicated IT support team.
Ask the administrator to log into the Microsoft 365 Admin Center and open an official support ticket regarding the Planner bucket scrolling bug.
Keep an eye on primary Microsoft tech discussion forums or the Microsoft 365 Service Health dashboard for official resolution updates.

Use Browser Zoom Controls as a Temporary Workaround
Adjusting the browser's zoom level forces the web interface to resize, temporarily exposing the hidden planner buckets.

Frequently Asked Questions
Why did the horizontal scrollbar disappear in Microsoft Planner?
This is typically caused by a frontend interface bug in a recent Microsoft Planner update, which affects how the board view renders horizontally in standard web browsers.
Can I use the Planner mobile app to view my buckets?
Yes. If the web interface is unresponsive or missing the scrollbar, using the Microsoft Planner mobile app on iOS or Android may allow you to view and interact with all your buckets normally.
How do I check the Microsoft 365 Service Health dashboard?
Microsoft 365 administrators can access the Service Health dashboard by logging into the Microsoft 365 Admin Center, navigating to the 'Health' section, and selecting 'Service health' to check for active Planner advisories.
