How to Turn Off the Task Completion Sound in Microsoft Planner

Product: Microsoft Planner
Device & OS: not provided
Scenario: Managing tasks and checking off completed items in Microsoft Planner via a web browser.
Observed behavior: A sound automatically plays when a task is completed, and Microsoft Planner lacks a built-in settings toggle to disable this specific audio notification.

Before you start

Ensure you are using a modern web browser such as Microsoft Edge, Google Chrome, or Mozilla Firefox, as these browsers support individual tab audio controls.

Solution 1Recommended

Mute the Planner Browser Tab

Use this workaround to silence the task completion sound without affecting the rest of your computer's audio.

Because Microsoft Planner does not currently offer a native option to toggle off the completion sound, utilizing your browser's built-in tab muting feature is the most effective workaround.

Locate the Planner Tab

Open your web browser and navigate to the Microsoft Planner tab where you are managing your tasks.

Right-click the Tab

Move your cursor to the top of the browser window and right-click directly on the Planner tab.

Select Mute Tab

Click on 'Mute tab' (or 'Mute site' depending on your browser) from the drop-down menu. This will instantly silence all sounds coming from Planner.

Audio Control: Muting the tab only affects Microsoft Planner; you will still hear audio from other browser tabs and desktop applications.

Solution 2

Submit a Request in the Microsoft Feedback Portal

Encourage Microsoft to add a native sound toggle by voting for the feature in the official community portal.

Frequently Asked Questions

Can I turn off the task completion sound if I use Planner inside Microsoft Teams?

There is currently no direct setting in Microsoft Teams to disable the Planner task completion sound. The tab-muting workaround only applies when you access Planner through a standalone web browser.

Will muting the Planner tab mute my Teams meeting or computer audio?

No. When you right-click and select 'Mute tab' in your browser, it strictly silences the audio generated by that specific tab. Your system sounds, media players, and Teams meetings will continue to function normally.

Is Microsoft planning to add a mute button for Planner tasks?

Microsoft has not announced an official timeline for a built-in mute setting in Planner. However, user requests are actively gathered on the Microsoft Feedback Portal, which heavily influences their future updates.
