Solution 1Recommended

Clear Browser Cache and Disable Chrome Extensions

Because Planner works perfectly in an incognito window, the problem is most likely caused by corrupted local browser cache or conflicting third-party extensions.

Incognito mode temporarily disables your browser extensions and ignores existing cached data. By clearing your cache and manually disabling extensions in your standard browsing session, you can eliminate the root cause of the NotFoundInStoreError.

1
Disable Extensions

Click the three-dot menu in the top-right corner of Chrome, go to 'Extensions', and select 'Manage Extensions'. Toggle off all active extensions.

2
Clear Browsing Data

Navigate to 'Privacy and security' in Chrome settings, click 'Clear browsing data', check cookies and cached images, and click 'Clear data'.

3
Restart and Test

Close the Chrome browser completely, reopen it, and navigate back to Office.com to launch Microsoft Planner.

Clear Browser Cache and Disable Chrome Extensions
Isolating the Extension: If Planner works after disabling all extensions, turn them back on one by one to identify which specific extension is causing the conflict.

Frequently Asked Questions

Why does Microsoft Planner work in Chrome's incognito mode but not in a normal window?

Incognito mode runs without utilizing your previously cached data and typically disables third-party browser extensions. If Planner works in incognito, it indicates that a corrupted cache file, stale cookie, or an active browser extension in your normal window is blocking the application from loading user settings.

What does NotFoundInStoreError mean in Microsoft Planner?

The NotFoundInStoreError generally signifies that the web application is unable to locate the required user session data or configuration settings in its expected storage location. This is often tied to local browser cache corruption or account synchronization delays.

How can I access my tasks if the Planner website is completely down for me?

If you cannot access the web version of Planner, you can view and manage your tasks by opening the Microsoft Teams desktop app and navigating to the 'Tasks by Planner and To Do' app, or by using the official Planner mobile application on iOS and Android.
