Planner stalls frequently

Question

Planner stalls frequently

Clyde Clark 10

On multiple machines in multiple browsers, Planner frequently stalls. This happens when doing anything with Planner - creating a new task, entering a name, selecting a date, entering subtasks, entering notes, etc. Is there some way around this issue? Is MS aware of it? Is MS working on fixing it? It is infuriating.

Based on the AI response:

I have cleared browser cache repeatedly. The issue occurs in the most up-to-date versions of Chrome, Edge, and FireFox.

The issue occurs when no browser extensions are enabled, and in "private browsing" mode.

The issue is independent of internet connection. Speed tests show good results, and all other web apps work normally.

As mentioned, the issue occurs in Chrome, Edge, and FireFox.

The issue occurs with all browsers at their latest versions. The issue is persistent and has been occurring for several months.

I have sent feedback repeatedly with no acknowledgement.

There isn't a tag available for the web app version of Planner, so I chose Teams -- Tasks because the issue also occurs with Planner within Teams.

Hi @Peter G McDermott,

Thank you for reaching out and sharing your experience with us. To resolve the issue, I would recommend trying the following steps:

Clear browser cache

Launch the browser, and press Ctrl + Shift + Delete to open the Clear browsing data utility.

Now, select All time from the Time range dropdown menu, tick the checkboxes for Cookies and other site data and Cached images and files, then click on Clear data towards the bottom.

Use a different browser

If the issue persists in one browser, try accessing Planner in another browser to see if the problem continues.

Open in incognito tab

Open in incognito tab can rule out cached data and session issue.

Contact Microsoft Support

If the issue persists, please use your organization's administrator account or contacting your IT administrator. They can submit a support request through the Microsoft 365 Admin Center for further assistance.

If you have any further questions or concerns, please feel free to reach out. I'll be ready to help.

Thank you for your time and understanding. Wishing you a great day ahead.

Hi @Clyde Clark,

Welcome to Microsoft Q&A forum.

Thank you for the detailed troubleshooting you’ve already done.

You confirmed the issue occurs across multiple machines, with up‑to‑date Chrome, Edge, and Firefox, in private mode with extensions disabled, and independent of the network. I appreciate you sharing this information.

To better understand and assist, could you please let me know which Microsoft 365 subscription you are using, such as Business Standard, Business Premium, or Enterprise E3 or E5? This helps me match guidance for your tenant features and the correct support path.

Once I have that information, I can advise on the next steps, including whether to escalate to Microsoft support or apply tenant-specific checks.

Thank you for your patience and understanding. Looking forward to your response.

Hi Jay,
Thanks for the reply. Sorry for the delay.
I am using Enterprise E3. We see the same issue with F2 as well.
This week, I have found if I launch Planner from within Teams as a new window, the issue seems to happen less frequently.

Frequent stalling issues with Microsoft Planner can be frustrating. While the context does not provide specific information about ongoing issues or fixes related to Planner stalling, it does mention that Planner is integrated with Microsoft Teams and is accessible through various platforms. If you are experiencing consistent performance issues, here are a few general troubleshooting steps you might consider:

Clear Browser Cache: Sometimes, clearing the cache can resolve performance issues.
Disable Browser Extensions: Certain extensions can interfere with web applications. Try disabling them to see if performance improves.
Check Internet Connection: Ensure that your internet connection is stable and fast enough for web applications.
Use Different Browsers: If the issue persists in one browser, try accessing Planner in another browser to see if the problem continues.
Update Browser: Ensure that your browser is up to date, as updates can improve performance and compatibility.
Contact Support: If the issue persists, consider reaching out to Microsoft support for assistance or to report the problem.

For the latest updates or known issues, checking the official Microsoft documentation or support channels may provide more insight into whether Microsoft is aware of the issue and if they are working on a fix.
