Fix Flagged Outlook Emails Missing from To Do Desktop and iOS Apps
Question details
Flagged Outlook emails are not syncing or appearing in the Microsoft To Do desktop and iOS apps, despite showing correctly in the web version.

- Product
- Microsoft To Do
- Device & OS
- Desktop and iOS
- Scenario
- Attempting to view flagged Outlook emails as tasks across different devices in Microsoft To Do.
- Observed behavior
- Flagged emails successfully sync to the To Do web app but remain completely missing from the desktop and iOS application views, even when using the same Microsoft account.
Ensure you have a stable internet connection and verify that you are signed in using the exact same Microsoft account (work, school, or personal) for both Outlook and all versions of Microsoft To Do.
Enable 'Show Completed Tasks' and Verify Account Settings
Since view settings do not sync across devices, you must manually enable completed task visibility on each app to ensure all flagged emails appear.
A common reason for discrepancies between the web app and desktop/mobile apps is that local view settings, such as hiding completed tasks, do not automatically carry over from the web interface.
Open Microsoft To Do on your desktop or iOS app. Tap or click on your profile picture to verify you are signed in with the identical account used in Outlook.
Locate and open the 'Flagged email' list from the main navigation sidebar in the app.
Tap the three-dot menu (More options) in the top right corner and select 'Show completed tasks'. You must do this separately on both the desktop and iOS applications.
Pull down on the list in iOS or click the sync button on the desktop to force a refresh. Allow a few minutes for the emails to populate.

Contact Microsoft To Do Support via In-App Messaging
If adjusting the settings does not resolve the sync failure between the Exchange server and the local apps, reaching out to support is the next best step.

Frequently Asked Questions
Why do flagged emails show on the web but not in the Microsoft To Do app?
The web version of Microsoft To Do often updates directly from Exchange servers in real-time. Desktop and mobile apps rely on localized syncs and device-specific settings, like 'Show completed tasks', which do not automatically sync across platforms.
How do I turn on the Flagged Email list in Microsoft To Do?
Open Microsoft To Do, navigate to Settings by clicking your profile icon, scroll down to the 'Connected apps' or 'Smart lists' section, and toggle the 'Flagged email' option to 'On'.
Can I use different accounts for Outlook and To Do to sync flagged emails?
No, the integration requires you to be signed in to both Microsoft Outlook and Microsoft To Do using the exact same Microsoft account (work, school, or personal).
