My To Do apps on iOS crashing.

Question

My To Do apps on iOS crashing.

Andrew J 30

Microsoft To Do apps crash as soon as they are opened on both iPhone and iPad. Microsoft support keeps saying I need to contact To Do through the app, even when I tell them that is impossible as it crashes within seconds of opening. Can anybody help me contact To Do technical support.

Hi Andrew. I see that they do suggest contacting them through the app, which of course is not possible for you at the moment... Have you tried uninstalling the To Do app, reinstalling?

Log in here https://login.microsoftonline.com/ to access To Do from your web browser on either your iPhone or iPad, you should then be able to 'contact support'; or you can head to the bottom of this page: https://support.microsoft.com/en-us/todo & select 'contact support'.
Good luck!

Thank you for your time and answer, Dina. I am a personal user so cannot use admin. I have uninstalled, reinstalled, clear a corrupt task and cleared and unlinked flagged emails. All I need now is to contact ToDo support. The ToDo support page ‘contact us’ selection at the bottom has no option to get ToDo support and the web browser version has no link to support either. Microsoft keep taking me round in circles!

Andrew - glad I could help a tad - I see what you mean, no way to get in contact with Microsoft support staff through the web browser. I'd try to follow these steps, if possible: https://support.microsoft.com/en-us/office/give-feedback-on-microsoft-to-do-43ac4b2d-6329-4ba1-b7f1-f7f22ed3adea& if not, "suggest a new feature" & suggest they fix your issue :)

Hi, Andrew J

This looks more like a wider Microsoft To Do app problem on iOS than a problem with your phone. Here are some suggestions you can try:

Email the To Do team directly at hstodo@microsoft.com, include your device model, iOS version, and say the app crashes on launch.

Use the web version as a temporary workaround so you can still access tasks while waiting for a fix.

If you have a lot of old completed tasks, it is recommended that you delete those from the web version first, then reinstall the app. That has been suggested as a practical cleanup step when crashes keep coming back.

Also add it to the Feedback Portal so the issue has a tracked report.

You can do some generic workarounds for your device such as free up storage, restart the device, and if needed try Reset All Settings without erasing personal data.

Thank you for your patience in reading, I hope this information has been helpful to you.

Thank you. I have written to Microsoft in Reading UK as I have been getting nowhere trying to contact the ToDo service dept. I will try that email address. Your other suggestions, old tasks etc. have all been done. Thanks again.
