Solution 1Recommended

Test on Another Apple Device and Report Feedback

Determine if the crashing issue is isolated to your specific device or an account/app-wide bug.

If standard troubleshooting like reinstalling the app fails, the problem may be rooted in an account sync issue or a bug within the current version of Microsoft To Do. Testing on a secondary device helps isolate the root cause so you know whether to wait for an app update or investigate your device further.

1
Sign in on a secondary device

Borrow or use another iPhone or iPad, download Microsoft To Do from the App Store, and sign in with your primary Microsoft account.

2
Monitor for crashes

Use the app normally for several minutes to see if the same crashing behavior occurs on the new device.

3
Submit feedback to Microsoft

If it crashes on multiple devices, the issue lies with the app or your account. Visit the Microsoft To Do feedback portal (feedbackportal.microsoft.com) to report the bug directly to their development team.

Frequently Asked Questions

Why does Microsoft To Do crash immediately upon opening?

Immediate crashes on launch are often caused by a corrupted local app cache, a pending iOS system update, or a known bug in the current app version. While reinstalling usually clears the cache, persistent crashes may require an official patch from Microsoft.

Will I lose my tasks if I delete and reinstall Microsoft To Do?

No, your tasks and lists are safely synced to your Microsoft account in the cloud. As long as you have internet access and sign back in using the same Microsoft account, your data will be restored automatically.

How can I view iPhone app crash logs if I don't have a Mac?

You can access basic crash logs directly on your iPhone by navigating to Settings > Privacy & Security > Analytics & Improvements > Analytics Data. You can then copy the text or share the log file via email or AirDrop.

Can an outdated iOS version cause Microsoft apps to crash?

Yes, running an older version of iOS or iPadOS can lead to compatibility issues with newer updates of Microsoft To Do. It is highly recommended to keep your device's operating system updated to ensure stability.
