Solution 1Recommended

Verify Microsoft Account and Test Alternate Browsers

Account mismatches or browser caching issues are the most common causes for missing task lists.

Sometimes, being logged into a different Microsoft account or experiencing a synchronization delay can make it look like your lists have been deleted. Verifying your credentials and testing another browser can quickly isolate the problem.

Check your signed-in account

Click your profile picture in the top right corner of the Microsoft To Do browser interface and verify that you are logged into the correct account.

Try an incognito window

Open a private or incognito browsing window and log into Microsoft To Do again to rule out any browser cache interference.

Test on a secondary device

Open the Microsoft To Do mobile or desktop app to see if the missing lists are still visible and syncing correctly there.

Verify Microsoft Account and Test Alternate Browsers

Security Reminder: Never share your password or account credentials publicly when seeking help on forums or community boards.
