Complete Tasks in Outlook and Submit Bug Feedback

Since there is currently no known Outlook setting to permanently fix this backend integration bug, you should use Outlook for time-sensitive task completion and formally report the issue to Microsoft.

Testing indicates that the Microsoft To Do application may fail to update Outlook's completion date accurately to the current day. Microsoft has not provided a built-in toggle or setting within Outlook to change or correct this specific synchronization behavior.

Until a patch is released, the most reliable workaround is adjusting your workflow for tasks requiring precise timestamp logging.

Complete critical tasks directly in Outlook

For any tasks where the completion date must be strictly accurate for compliance or logging purposes, open the Outlook client and mark the task as completed from the Outlook Tasks view instead of using the To Do app.

Submit feedback to the Outlook team

Open Microsoft Outlook, navigate to the 'Help' tab on the ribbon, and select 'Feedback'. Choose 'Report a Problem' and detail how To Do tasks are appearing with the previous day's date.

Report the issue to the To Do team

Open the Microsoft To Do app, click on your profile picture or settings gear icon, select 'Settings', and navigate to 'Get Support' or 'Send Feedback' to report the date offset issue.

Frequently Asked Questions

Why does Microsoft To Do sync tasks with yesterday's date in Outlook?

This is a known backend synchronization bug between Microsoft To Do and Outlook. Time zone conversions and server sync delays between the two applications often cause the logged timestamp to shift backwards by one day when viewing it in the Outlook client.

Is there a setting in Outlook to fix the task completion date?

No, testing confirms there is currently no specific setting, toggle, or configuration within Outlook's options that can manually override or correct this inaccurate date sync from Microsoft To Do.

Does a time zone mismatch cause task date errors?

Yes, although this specific bug exists independently, a mismatch between your device's local time zone, your Outlook Web App time zone settings, and your overall Microsoft account region can exacerbate syncing errors. Always ensure they are perfectly aligned.
