The quickest safe fixes are to fully close Loop, sign out and back in, check service status, and update the app or browser. Your pages are usually still in Microsoft 365, so start with the low-risk steps before you clear cache or repair anything. ## What the restart looks like and what it usually means A restart loop usually shows up in one of three ways: Loop opens to the splash screen and never finishes loading, the app closes and immediately opens again, or you keep getting signed out and sent back through Microsoft sign-in. In most cases, that points to one of three things: Loop’s local cache is corrupted, your sign-in token is stuck, or Microsoft 365 is having a service problem. That does not usually mean your notes are gone. Loop stores content in Microsoft 365, so a restart loop is more often an access or loading problem than a data-loss problem. If the app only fails at startup, think session or cache first. If it happens after a password change, MFA prompt, or account switch, the sign-in session is a strong suspect. If lots of coworkers are seeing the same thing at the same time, it is more likely a service issue than anything on your device. ## Before you start This applies to Microsoft Loop on Windows, macOS, and in supported browsers such as Chrome and Edge. Most of the first fixes do not need administrator access, but repairing the app on Windows may require local admin permission depending on your company’s settings. You do not need to back up your Loop pages before the first steps. Your content is stored in Microsoft 365, and the first fixes here are meant to preserve it. Before you change anything, do these two safe checks: - Try Loop once in another browser or on another device with the same work account. - Ask a colleague whether they are seeing the same restart loop. Those two checks help you tell the difference between a local device problem and an account or service problem. ## When this happens on one device, one browser, or every device Use the pattern to narrow the cause before you start clearing things. If Loop restarts only on one computer or phone, the problem is probably local to that device: cached data, an outdated app, or a damaged profile. If it happens only in one browser, the browser profile, extensions, or site data are the likely cause. If it happens in both the desktop app and the browser, the account, tenant, or Microsoft service is more likely. Here’s a simple way to test it: - Open Loop on the same account in another browser. - Try a private or incognito window. - Try the same account on a second device. - If possible, try a different account on the same device. If one browser works and another does not, the issue is local to that browser. If your account fails everywhere, but a colleague’s account works on the same device, that points to an account or tenant issue. If nobody can get in, stop treating it like a device problem and check Microsoft 365 status or contact IT. ## The first fixes to try without risking your data Start with the lowest-risk fixes. These do not delete your Loop pages, because your content is tied to Microsoft 365 rather than stored only inside the app. 1. Fully close Loop. Close the Loop window, then make sure it is not still running in the background. On Windows, check the taskbar tray and Task Manager. On a browser, close every Loop tab and then close the browser completely. 1. Open Loop again and test once. ```text Loop opens past the splash screen and stays open. ``` Expected result If it still restarts, move on. 1. Sign out of Loop or Microsoft 365, then sign back in. Use the account menu in Loop or the Microsoft sign-in page, sign out fully, then sign in again with the same work account. ```text You are prompted to sign in once, then Loop loads your workspace. ``` Expected result If it keeps looping at sign-in, the session token is probably stale. 1. Check Microsoft 365 service status. If your organization has a status page, check there first. If not, ask a colleague whether they are seeing the same behavior. If several people are affected, this may not be your device at all. 1. Update Loop or your browser. Use the Microsoft Store for the app, or update Chrome, Edge, or whichever browser you use for Loop. Then reopen Loop and try again. 1. Try another browser or device. If Loop works in another browser or another device, you have narrowed it down to the original app, browser profile, or device setup. That is useful information for the next step or for IT. ## If Loop still restarts, clear the cache or repair the app If the quick fixes do not help, clear the cached data that Loop is using. This is still a safe step if you only remove site data or app cache, not your Microsoft 365 files. For Loop in a browser, clear site data for Microsoft Loop and Microsoft 365\. In Chrome or Edge, you can usually do this from the site settings or browser privacy settings. After clearing, sign back in and test again. ```text Browser settings > Privacy and security > Site data / Cookies > View permissions and data stored across sites ``` Settings path Remove data for the Loop and Microsoft 365 domains your organization uses, then reopen the browser. Expected result: Loop loads normally and asks you to sign in again if needed. If it still restarts, the browser profile may be the issue. Try a fresh browser profile or another browser. For the desktop app on Windows, use the app repair option first before anything more aggressive. ```text Windows Settings > Apps > Installed apps > Microsoft Loop > Advanced options > Repair ``` Settings path Repair keeps the app installed and tries to fix damaged files. If Repair does not help, use Reset only if you are comfortable re-signing in and reloading local app state. Reset clears local app data. Your Microsoft 365 content should still be in the cloud, but you may need to sign in again and reload local settings. Do not uninstall, delete profile folders, or remove browser data broadly before you know which account and browser are affected. That can make troubleshooting harder and can sign you out of other work apps. If you are on a managed Windows device and the app still loops after Repair, ask IT whether Office repair or a profile rebuild is needed. If you are on macOS or mobile, use the app’s own update and sign-in reset options rather than trying to remove unrelated system files. ## How to tell the problem is actually fixed The fix worked if Loop opens past the splash screen, shows your recent pages, and keeps running after you leave it open for a few minutes. A better test is to close Loop completely, reopen it, and then open one of your recent pages. If that page loads and stays open, the restart loop is gone. ```text Loop opens normally Recent pages appear The app stays open after relaunch ``` Expected output A second check is to sign out, sign back in, and open the same page again. A real fix should survive that cycle without bouncing you back to the splash screen. If the problem only disappears for a moment and then comes back after a reboot or browser restart, the underlying cache, profile, or account session may still be damaged. ## When to stop troubleshooting and call IT Stop local troubleshooting and escalate if the issue affects every device you try, every browser you try, or every account in your organization. That usually points to a tenant setting, conditional access policy, authentication problem, or a Microsoft service issue that only an admin can confirm. You should also contact IT if: - Loop works for other users but not for your work account. - The problem started right after a password change, MFA change, or device compliance update. - You see repeated sign-in prompts with no error message. - Repair and cache clearing did not help. - The same restart happens in a brand-new browser profile or on a second device. If your company has Microsoft 365 admin support, give them the exact symptom, the device or browser you tested, and whether it affects one account or many. That saves time and makes it easier to separate a local cache problem from a service or policy issue. ## Conclusion If Loop is still restarting after the safe fixes, narrow it down to one device, one browser, or one account and hand that pattern to IT. If it only breaks in one browser or on one machine, that is the clearest clue for the next fix. ## Frequently Asked Questions ### Will clearing the cache delete my Loop pages? Usually not. Your Loop content is stored in Microsoft 365, so clearing browser site data or repairing the app should not erase the pages themselves. You may need to sign in again and let the app reload your content. ### Why does Loop keep restarting only in one browser? That usually means the browser profile, cached site data, or an extension is interfering with Loop. Try a private window, then a different browser, and clear site data for Microsoft 365 if the private window works. ### Why does Loop restart after I sign in? A sign-in session can get stuck or expire badly after a password change, MFA change, or account switch. Signing out fully and signing back in again is usually the first fix to try. ### How do I know if it is a Microsoft outage? If the issue affects many users, appears in different browsers and devices, and starts at the same time, it is more likely a service issue. Check your organization’s Microsoft 365 status source or ask IT to confirm before you keep clearing local data.
