How to Mute Task Completion Sounds in Microsoft To Do

Product: Microsoft To Do
Device & OS: not provided
Scenario: Completing daily tasks in the application and wishing to silence the accompanying completion chime without muting all device audio.
Observed behavior: The application plays a distinct notification sound upon task completion, and there is no visible in-app setting to disable only this specific sound.

Before you start

Verify that your device's operating system offers a volume mixer or per-app volume controls, as this will be required for the primary workaround.

Manage System Volume and Submit Feature Feedback

Because Microsoft To Do does not currently offer a dedicated setting to mute only the task completion sound, you must use system-level volume mixers or submit feedback for future updates.

Community moderators have confirmed that the specific ability to disable just the task completion chime is currently unavailable. Product development relies heavily on user votes, so submitting an official request is highly encouraged.

Mute the App via System Settings (Windows)

Right-click the speaker icon in your Windows taskbar and select 'Open Volume mixer'. Locate Microsoft To Do in the list of active applications and drag its volume slider to zero to mute all app sounds.

Submit Feedback in the App

Open Microsoft To Do, click on your profile picture or username, navigate to 'Settings', and select 'Suggest a Feature' or 'Get Support' to request the mute toggle.

Vote on the Microsoft Feedback Portal

Visit the official Microsoft Feedback Portal in your web browser, search for 'To Do completion sound', and upvote existing requests to increase the feature's visibility to the development team.

Manage System Volume and Submit Feature Feedback

Temporary Limitations: Muting the application through your system's volume mixer will silence all sounds from Microsoft To Do, not just the task completion chime.
