How to Fix Deleted Flagged Emails Remaining in Microsoft To Do
Question details
The user needs to remove deleted flagged Outlook messages that are improperly persisting in Microsoft To Do and resolve app freezing issues.
- Product
- Microsoft To Do
- Device & OS
- not provided
- Scenario
- Synchronizing flagged emails between Microsoft Outlook and Microsoft To Do.
- Observed behavior
- Microsoft To Do continues to display hundreds of flagged emails that were already deleted in Outlook, and the application becomes unresponsive when attempting to disable the flagged-email setting.
Ensure you have a stable internet connection and verify that both Microsoft Outlook and Microsoft To Do are currently signed in using the exact same Microsoft 365 mailbox account.
Verify Account Connection and Manually Refresh To Do
Use this solution to ensure both apps are communicating with the same Exchange server and to force a fresh synchronization.
Synchronization mismatches often occur if the authentication token expires or if the apps are caching outdated server data. Resetting the connection helps clear phantom emails.
Open Microsoft Outlook and Microsoft To Do. Navigate to the account settings in both applications and verify that the exact same email address is actively logged in.
In the Microsoft To Do desktop app, click on your profile picture in the top left corner, select 'Settings', and click the 'Sync' button to force a manual refresh.
If the manual sync fails, log out of Microsoft To Do completely. Restart your device, open the app, and sign back in to establish a fresh connection with the server.
Collect Tenant Details and Escalate to IT Support
Use this solution if local synchronization fixes fail, indicating a deeper server-side or tenant-level issue.
Experience a Seamless and Lightweight Office Suite with WPS Office
While WPS Office does not directly manage Microsoft To Do's email synchronization, it offers a fast, lightweight, and highly reliable alternative to heavy office ecosystems for your daily document processing tasks.
- 1. Visit the Official Website: Go to the official WPS Office website on your computer or mobile device.
- 2. Download the Installer: Click the 'Free Download' button to get the correct version for your operating system.
- 3. Install and Launch: Run the downloaded installer, follow the simple on-screen instructions, and launch WPS Office to enjoy a streamlined workspace.
Frequently Asked Questions
Why do deleted Outlook emails still show up in Microsoft To Do?
This generally happens due to a caching issue or a temporary synchronization lag between the Microsoft 365 Exchange server and the local To Do application database.
How can I prevent Microsoft To Do from freezing when I change settings?
To prevent freezing, ensure the app is fully synced before modifying heavy settings like flagged emails. If it frequently crashes, clearing the app's cache or reinstalling the application can resolve corrupt background processes.
Does unflagging an email in Outlook remove it from Microsoft To Do?
Yes, properly unflagging an email in Outlook should automatically remove it from the Flagged Emails list in Microsoft To Do once the two applications successfully synchronize.
