How to Fix Microsoft To Do Stuck on Synchronization Failed

Product: Microsoft To Do
Device & OS: Windows, Android, Web
Scenario: Attempting to sync task lists or load the Microsoft To Do app across multiple devices and platforms.
Observed behavior: The application remains stuck on the message 'We are getting your tasks list ready' or explicitly displays 'Synchronization failed' across all platforms, even though other Microsoft services are functioning normally.

Before you start

Before escalating the issue, verify your internet connection and ensure your Microsoft account password has not been recently changed, as this can temporarily pause cloud syncing.

Solution 1Recommended

Check Service Health and Contact Microsoft Support

Because the synchronization issue spans all platforms (Web, Windows, and Android) and local troubleshooting has failed, the problem is likely on Microsoft's cloud servers and requires their intervention.

When cloud synchronization fails universally across all your devices, it typically indicates a service-side outage or a specific account glitch on the server. Local fixes like reinstalling the app will not resolve this.

Such service issues are usually temporary, but reporting your specific case helps Microsoft's engineering team isolate and fix the problem faster.

Check Microsoft Service Status

Visit the official Microsoft 365 Service Health status page to see if there are any ongoing outages affecting Microsoft To Do or related cloud infrastructure.

Gather Account and Error Details

Note down your affected Microsoft account email, the platforms where the error appears (e.g., Windows 11, Android), and the exact error messages such as 'Synchronization failed' or 'We are getting your tasks list ready'.

Email the To Do Support Team

Send a detailed email to hstodo@microsoft.com. Include your account details and explicitly mention the local troubleshooting steps you have already completed so they can escalate the issue immediately.

Check Service Health and Contact Microsoft Support

Wait for a Resolution: Cloud synchronization issues can take a few hours to be resolved by Microsoft. Avoid logging out or uninstalling the app while waiting, to prevent losing any locally saved tasks that haven't synced yet.

Solution 2

Perform Basic Local Troubleshooting

If you haven't done so already, ensure your local app state isn't the root cause of the synchronization failure.

Frequently Asked Questions

Why does Microsoft To Do say 'We are getting your tasks list ready' forever?

This usually happens when the application cannot establish a stable connection with Microsoft's cloud servers to fetch your task data. It can be caused by server-side outages, network restrictions, or corrupted local authentication tokens.

How long do Microsoft service-side synchronization issues usually last?

Cloud-side outages are typically temporary and are often resolved by Microsoft's engineering team within a few hours. You can monitor the Microsoft 365 Service Health dashboard for real-time updates on server status.

Will I lose my tasks if Microsoft To Do fails to sync?

No, tasks created offline or locally while the server is down will remain on your device. Once the synchronization issue is resolved by Microsoft, your local tasks will safely sync to the cloud. However, you should avoid uninstalling the app while it is unable to sync, as doing so will permanently delete your unsynced local data.
