How to Fix Microsoft To Do Sidebar Disappeared
Question details
The user is unable to view or access the side navigation pane in Microsoft To Do, which contains lists such as Work, Personal, and Movies.
- Product
- Microsoft To Do
- Device & OS
- Windows
- Scenario
- Trying to navigate between task lists in the Microsoft To Do desktop app, but the left sidebar is completely hidden.
- Observed behavior
- The sidebar has disappeared and remains missing even after the user restarts the computer and signs back into their Microsoft account.
Make sure your secondary monitors (if any) are fully plugged in, as multi-display setups frequently cause window scaling and resizing glitches in Windows apps.
Resize the Sidebar from the Screen Edge
This issue is often a bug caused by multiple displays where the sidebar is accidentally resized to zero width when a monitor is unplugged.
When switching between multi-monitor and single-monitor setups, Microsoft To Do sometimes miscalculates the window boundaries. This forces the sidebar width to zero, rendering it invisible.
Open Microsoft To Do and click the maximize button in the top right corner so the window fills your entire screen.
Move your mouse pointer to the far right edge of the application window (or the far left edge, depending on how the UI shifted) until your pointer changes into a horizontal double-headed resize arrow.
Click and drag the edge inward (to the left). This forces the application layout to refresh and should restore the sidebar to its normal width.
Repair or Reset Microsoft To Do
If resizing the window does not restore the sidebar, use the built-in Windows Settings to repair or reset the application to its default state.
Reinstall from the Microsoft Store
If the app installation is corrupted and neither resizing nor resetting works, a clean reinstall will deploy a fresh, working interface.

Frequently Asked Questions
Why did my Microsoft To Do sidebar suddenly disappear?
This is typically caused by a multi-display bug. When you unplug a secondary monitor, the application layout may miscalculate its dimensions, resizing the sidebar to zero width and making it invisible.
Will resetting Microsoft To Do delete my tasks and lists?
No. While resetting the app from Windows Settings clears local preferences and forces you to sign in again, all your tasks and lists are securely synced to your Microsoft account in the cloud. They will automatically populate once you log back in.
Is there a specific setting to hide or unhide the sidebar in Microsoft To Do?
Currently, the desktop version of Microsoft To Do does not feature a dedicated menu setting or button to permanently hide the left sidebar. If it vanishes, it is almost always due to a software UI glitch rather than an intentional setting.
