Microsoft planner is not working

Hi @David Baron, 

Thank you for reaching out to the Microsoft Q&A forum and sharing the details of your issue about Microsoft Planner. 

Please refer that this forum is a public platform. To help protect your privacy, we’ve updated your post to remove your organization’s domain name. In the future, we kindly ask that you avoid including personal or organizational information when posting errors or screenshots, to ensure your data remains secure.  

To better assist you, could you please provide the following details? 

1. Screenshot of the issue 

A screenshot of what you’re seeing when the problem occurs will help us understand the situation more clearly. 

2. Steps you took before the issue appeared 

If possible, please describe the actions you performed leading up to the issue. For example, were you accessing Planner through Teams, a browser, or the Microsoft 365 portal? 

3. Browser and device information 

Let us know which browser and device you’re using (e.g., Edge on Windows 11, Chrome on macOS, etc.). 

4. Any error messages

If you received an error message, please include that in your reply. 

In the meantime, here are a few steps you can try that may help resolve the issue: 

• Clear your browser’s cache and cookies, then restart the browser and try accessing Planner again. 
• Try a different browser or use incognito/private mode to see if the issue persists. 
• Access Planner directly via tasks.office.com instead of through Teams. 
• If Planner loads but shows an error, try removing everything after the last “/” in the URL and reload the page. 

If these steps don’t resolve the issue, we’ll be happy to investigate further once we receive the additional information mentioned above. 

Looking forward to your reply so we can continue assisting you.
