To Do app disappeared from Outlook app on iPhone / iPad

If the To Do app has disappeared from the Outlook app on your iPhone or iPad, it could be due to a temporary glitch or an issue with the app's integration. Here are a few steps you can try to resolve the issue:

1. Restart the Outlook App: Close the Outlook app completely and reopen it to see if the To Do app reappears.
2. Check for Updates: Ensure that both the Outlook app and your device's iOS are updated to the latest version. Sometimes, updates can fix bugs or glitches.
3. Reinstall the Outlook App: If the problem persists, consider uninstalling and then reinstalling the Outlook app. This can often resolve integration issues.
4. Check Settings: Make sure that the To Do integration is enabled within the Outlook app settings.

If none of these steps work, it may be worth checking online forums or Microsoft's support pages to see if other users are experiencing similar issues, as it could be a broader problem that Microsoft is addressing.

Dear @Stephen Vaughan, 

Thank you for posting your question in the Microsoft Q&A forum.  

Could you tell me if you have checked the To Do app on the Outlook web browser yet? Is it displaying normally there? 

Could you please check the version of the Outlook app on your iPhone and iPad for me? 

What is the iOS version on your iPhone and iPad? 

Are any of your colleagues experiencing a similar issue? 

In the main screen interface of the Outlook app, could you please click on Apps and show me which apps are currently displayed there? Is the To Do app there? If it is, please move the To Do app up to the Pin section so the To Do app appears on the outside bar. If it is also missing from the Apps section, please answer all the questions above fully so I can provide the next step. 

Looking forward to your response!
