Solution 1Recommended

Repair or Reset the Microsoft To Do App

Use the built-in Windows Settings to repair or reset the app, which can fix corrupted local application data causing the login loop.

Resetting the app clears its local cache and data, often resolving issues where the login screen fails to load properly.

Open Windows Settings

Press the Win + I keys on your keyboard to open the Windows 11 Settings menu.

Navigate to Installed Apps

Click on 'Apps' in the left-hand menu, then select 'Installed apps' from the right pane.

Access Advanced Options

Scroll down or search for 'Microsoft To Do'. Click the three-dot menu icon next to it and select 'Advanced options'.

Repair or Reset

Scroll down to the Reset section. First, click 'Repair' and test the app. If you still cannot add your work account, click 'Reset' to clear all local app data.

Data Safety: Resetting the application will not delete your tasks, as they are securely synced to your Microsoft account online.

Solution 2

Clear Windows Credentials and Store Cache

Remove obsolete or conflicting account credentials from your system and reset the Microsoft Store cache.

Solution 3

Reinstall the App and Consult IT Support

Start fresh by completely reinstalling Microsoft To Do, and verify with your IT department if organizational policies restrict desktop app access.

Frequently Asked Questions

Why can I access my work account on the web but not on the desktop app?

Desktop applications rely on Windows integration and local cached credentials, which can sometimes become corrupted. Additionally, many organizations apply specific security policies (like MDM or Intune) that allow web access but block logins from unmanaged desktop applications.

Will resetting the Microsoft To Do app delete my tasks?

No, your tasks will not be lost. Resetting the application only clears the local app cache and settings on your Windows 11 device. Once you successfully log back in, all your tasks will sync from your Microsoft account.

How do I know if my organization blocks adding work accounts?

If you have tried reinstalling the app and clearing credentials but the 'Add account' button still refreshes or fails silently, it is highly likely a policy restriction. You will need to contact your IT administrator to verify if personal desktop access is restricted for your account.
