Start by checking your account status, trying the web version, restarting the app, and making sure you’re signed in with the right Microsoft account. If those don’t work, use the browser and another device to tell whether the problem is with the account, the app, or Microsoft’s service. ## What the login problem usually looks like The problem usually shows up in a few familiar ways: the sign-in screen keeps coming back after you enter your password, the app opens to a blank page, you get a generic message like “Something went wrong,” or your lists open but don’t match what you see on another device. ```text The exact message varies. Common symptoms include a sign-in loop, a blank app window, or a generic “Something went wrong” message. ``` Symptom Sometimes the app looks signed in, but your tasks never load. Other times it accepts the account details and then loops back to the sign-in page. If that happened right after a password change, a device update, or a network change, that points to a stale session, a browser or device sync glitch, or a connection problem rather than missing tasks. ## Before you start This applies to Microsoft To Do on the web and on supported Windows, mobile, and browser-based installs. You do not need administrator rights for the first checks, and you should not clear app data, remove the account, or change deeper settings until you’ve confirmed your tasks still exist in the web version or on another device. Safe checks to do first: - Make sure you know which Microsoft account should hold your tasks. - Check whether the same email address works in a browser. - Confirm the device has a working internet connection before changing settings. - If you use a VPN, proxy, DNS filter, or privacy tool, be ready to turn it off briefly for a test. ## When this fix applies and when it doesn’t The quickest way to avoid the wrong fix is to test the account first, then the app, then the device. If you can log in on the web but not in the app, don’t start with password recovery. If you can’t log in anywhere, focus on account recovery instead of clearing the app over and over. If the app keeps looping after a password change, update, or switch between networks, the session stored on the device is often the problem. If the same account works on one device but not another, that points to a device-specific problem rather than a bad password. If Microsoft To Do is down for everyone, changing settings on your device usually won’t help. In that case, waiting is better than repeatedly retrying sign-in or clearing settings that are already correct. ## The quickest fixes that solve most sign-in problems Start with the safest steps, in this order. 1. Confirm the right Microsoft account is being used. If you have more than one Microsoft account, it’s easy to sign in with the wrong one and think your tasks disappeared. Look closely at the email address on the sign-in screen and compare it with the one you normally use for Microsoft To Do. 2. Check the account status, then try signing in on the web. Make sure the account is active and that you can complete sign-in in a browser. Open Microsoft To Do in a browser and sign in there with the same account. ```text Use the Microsoft To Do web version with the same Microsoft account. ``` Browser sign-in check If the web version opens and shows your tasks, the account is fine and the problem is probably the app, its cached session, or the device. If the browser fails too, the issue is more likely with the account or Microsoft’s service. 1. Close the app completely and open it again. On mobile, swipe it away from the app switcher. On Windows, close the window and make sure it’s not still running in the background, then reopen it. If the app signs in normally after a restart, the session was likely stuck. If it loops again, move on. 1. Check your internet connection. A weak or interrupted connection can stop sign-in and sync at the same time. Try another website or app that needs the internet. 2. Disable VPN, proxy, or filtering tools temporarily. Some VPNs, privacy tools, DNS filters, and ad-blocking apps can interfere with Microsoft sign-in pages or background sync. Turn those tools off only long enough to test sign-in. If the app works after that, re-enable them one at a time so you can see which one caused the problem. If none of these fixes help, the issue may be a stale app session or a sync problem on the device rather than the account itself. ## How to tell if it’s working again You’ll know the fix worked when Microsoft To Do signs in cleanly, opens your lists without sending you back to the login screen, and shows your tasks instead of an empty or partial view. A good check is to make one small change, such as creating a test task or marking one item complete, and then open Microsoft To Do on another device or in the browser. If the change appears in both places, sync is working again. If the app opens normally but the change never shows up elsewhere, sign-in may be fixed but sync is still lagging or blocked on one device. If the web version and one device agree, but a second device does not, the problem is probably limited to that second device. That’s useful, because it means you do not need to keep changing account settings on every device. ## If it still won’t log in, try these next If the quick checks fail, move to the next level of fixes. 1. Check the device date and time. A wrong clock can break sign-in tokens and make Microsoft services refuse the connection. ```text Date and time settings ``` Settings path Turn on automatic date and time if your device offers it, then try signing in again. If that fixes it, the issue was the device clock, not your account. 1. Update Microsoft To Do and the device system software. An outdated app or operating system can leave you with a sign-in bug that Microsoft has already fixed in a newer version. If the app still won’t open correctly after updating, the installation itself may be damaged. 1. Clear the app’s local data or cache. This can remove a stale sign-in session without affecting the tasks stored in your Microsoft account. Only clear app data or cache if you’ve already confirmed your tasks exist in the web version or on another device. That way, if the local app session is the problem, you can sign in again and let the lists resync. 1. Remove the account from the app and add it again. This forces a fresh sign-in token and often fixes a login loop or “something went wrong” message. 2. Use Microsoft account recovery if the password or security check is the real problem. If you cannot sign in on the web either, reset the password or complete the account recovery steps first. Until that is fixed, the To Do app will keep failing for the same reason. If the app works on another device but not this one after all those steps, the problem is probably local to that device. If it fails everywhere, the account recovery path is the right place to stay focused. ## When the issue is likely on Microsoft’s side If the same account fails in the app and in the browser, and the error started for no clear reason at the same time on more than one device, the problem may be on Microsoft’s side. The same is true if you can sign in, but tasks will not sync anywhere and the behavior is the same after you’ve checked your account, connection, VPN, and device time. That is the point to stop changing settings and wait a bit before trying again. Repeating the same sign-in steps over and over will not fix a service issue, and it can make it harder to tell what changed. ## Conclusion If you’re still blocked, test the web version again from a different browser or device before changing anything else. That will tell you whether you’re dealing with an account problem, a device problem, or something Microsoft needs to fix. ## Frequently Asked Questions ### How do I know if my Microsoft To Do tasks are gone or just not syncing? If your tasks show up in the web version or on another device, they are still in your Microsoft account. That points to a sync or app problem on the device that is failing to show them. ### What should I do if Microsoft To Do keeps looping back to sign-in? First confirm you’re using the right Microsoft account, then try the web version, restart the app, and check your internet connection. If the loop continues, stale app data, a VPN or proxy, or a device sync problem is the more likely cause. ### When should I wait instead of changing settings again? If the same sign-in problem happens across devices and in the browser after you’ve already checked your account and connection, the issue may be on Microsoft’s side. At that point, waiting is safer than repeatedly clearing settings or reinstalling the app.
