Start with the safest fixes first: retry the app, check your connection, and force a refresh. If it only happens on one device, it’s probably local; if it happens everywhere, the problem is more likely account- or service-related. ## What slow loading usually looks like in Microsoft To Do Slow loading can show up in a few different ways. You might see a blank screen for a while before your lists appear, a spinner that never seems to finish, or a list that opens but doesn’t show recent task changes right away. Some people notice the app freezes as soon as it launches, while others can browse once it finally loads but new tasks, completed items, or shared-list updates arrive late. The pattern matters. If the app eventually opens but always takes far too long, that often points to sync trouble or a cache problem. If it hangs on launch only after an update, the app install itself may be the issue. If it is slow only at certain times of day, [a network or Microsoft](https://todayfixtech.com/microsoft-365-tips-tricks/) service issue is more likely. ## Before you start This applies to Microsoft To Do on phones, PCs, and the web version. The fixes below are safe to try on a normal user account; you do not need administrator access for the first checks, but some repair or reset steps on Windows may require admin permission depending on how the app is installed. You do not need to back up your tasks before the first steps, because they are tied to your account. The one caution is unsynced local changes on a device that has been offline. Do these two safe checks first: - Try loading a different list or switching between lists once. - Check whether other apps or websites are also slow, which can point to your connection. ## Symptom ```text Blank screen, spinner, or delayed sync when opening Microsoft To Do ``` Symptom This usually appears right after launch, when switching lists, or when you expect a recent task change to sync but it takes a long time to show up. ## How to tell if the slowdown is only on one device First, separate a local problem from an account or service problem. Open Microsoft To Do on another device or in the web version if you use it, then compare the behavior. If one phone is slow but your PC and browser load normally, the issue is probably local to that device. If every device is slow, the problem is more likely tied to your account sync or a Microsoft-side issue. If you use Microsoft To Do through a browser, try a private or incognito window. That helps separate a site issue from a browser cache or extension problem. If the browser version is also slow in private mode, the issue is less likely to be your saved browser data. ## Fix 1: Retry the app and force a refresh Use this on the device that is slow. No special privileges are needed. 1. Close Microsoft To Do completely, then open it again. 2. If it still loads slowly, switch to another list and then back to the one that was stuck. 3. If you are using the web version, refresh the page once. The app should reopen without a long blank screen, and the list should appear quickly. If it still hangs or syncs late after a retry, move on to the connection check. ## Fix 2: Check the connection and test sync Use this on the same device. No special privileges are needed. 1. Open another app or website and see whether it loads normally. 2. If your connection looks weak, move to a stronger network or wait for the connection to stabilize. 3. Open Microsoft To Do again and check whether recent task changes appear. If the network was the problem, To Do should load normally once the connection is steady. If other apps work fine but To Do still lags, the issue is less likely to be the network and more likely cache, sync, or service related. ## Fix 3: Clear the app’s cache or reset it without losing tasks Use this on the slow device. On Windows, these steps may require admin permission depending on how the app was installed. 1. Open the app settings for Microsoft To Do on the affected device. 2. Use the option to clear the app’s cache if it is available. 3. If clearing cache does not help, use the app’s reset or repair option rather than uninstalling right away. ```text Windows Settings > Apps > Installed apps > Microsoft To Do > Advanced options ``` Settings path You should be able to sign back in and see your tasks return from your account. If the app opens faster after this, the cache was likely the problem. If it is still slow, the install may be damaged enough that reinstalling is the next step. Resetting can remove unsynced local changes on that device. Check another device first if you have edits that may not have synced yet. ## Fix 4: Reinstall the app if reset does not help Use this only after cache clearing or reset does not fix the problem. On Windows, this may require admin permission; on mobile, you only need the normal app uninstall permission. 1. Uninstall Microsoft To Do from the slow device. 2. Install it again from the normal app source for that device. 3. Sign in and let it sync fully before making more changes. After reinstalling, the app should load normally and pull your tasks back from your account. If it is still slow after a clean reinstall, the issue is probably not the local install anymore. ## How to tell if the slowdown is actually gone You’ve likely fixed it when Microsoft To Do opens without a long blank screen, your lists appear quickly, and recent task edits show up without a long delay. Test the parts that were slow before: open the same list that used to stall, add a quick test task, mark it complete, then check whether the change appears on another device or in the browser. If sync is healthy, the update should show up almost immediately or after only a short refresh. If the app still hesitates but eventually catches up, the slowdown may be reduced but not gone. If one device is now fast and another is still lagging, that points back to a device-specific cache or install problem on the slow device. A good final check is to restart the app once more. If it opens normally after a restart, the fix held. If the slowdown returns every time after a device reboot or app update, you’re probably dealing with a recurring local issue or a service-side sync delay. ## How to keep Microsoft To Do loading fast later Keep the app updated on every device you use. Updates often fix sync and startup problems that show up after a change in the app or the operating system. Try not to edit the same shared list in several places at once if your connection is shaky. That can create sync conflicts and make the app feel sluggish while it sorts things out. If you work across phone, PC, and browser, give each device a moment to finish syncing before making a lot of changes on the next one. If slow loading keeps coming back, watch for the same pattern each time. If it happens after a weak network connection, the fix is usually to wait for a better connection before opening the app. If it happens after every update or only on one device, clearing the cache or resetting that device again may be enough. If every device slows down at once, the issue is more likely on Microsoft’s side or tied to your account sync, so checking from another device can save you time before you keep changing settings. ## Conclusion If Microsoft To Do is still slow after these steps, focus on the one place where it fails most often: one device, one browser, or every device. That tells you whether to keep working on a local cache or reinstall, or whether it makes more sense to wait for sync to recover. Try the next most targeted fix rather than repeating the same one. ## Frequently Asked Questions ### Will resetting Microsoft To Do delete my tasks? Your tasks are tied to your account, so they normally return after you sign back in. The main risk is unsynced local changes on a device that has been offline, so check another device first if you’re unsure. ### Why is Microsoft To Do slow only on one device? That usually points to a local cache issue, a bad install, or a device-specific network problem. If other devices load normally, start with repair, reset, or reinstall on the slow device. ### Should I reinstall Microsoft To Do or clear cache first? Clear cache or use repair/reset first, because those are faster and less disruptive. Reinstall is the next step if the app is still slow after that. ### What if Microsoft To Do is slow everywhere? If the problem shows up on every device, check whether you can load the web version and whether recent tasks sync at all. That usually points to an account sync delay or a Microsoft service issue rather than a single device problem.
