How to fix Haldor not working
Haldor builds tools for schools on top of Microsoft 365 and Microsoft Teams. Teachers plan lessons, set and grade assignments and track progress. Students and guardians follow schedules and results. Most problems come from the Microsoft sign-in, the Teams connection, a setting the school controls, or the Haldor service itself. Find your symptom below.

Login Failed
Sign-in is refused. Haldor works within the Microsoft account your school uses, so the account you sign in with matters.
- Sign in with your school Microsoft account, not a personal one.
- If Microsoft asks you to verify, complete that check first, then return to Haldor.
- If the message says the password is wrong, reset it through your school's Microsoft sign-in, and check spam for the email.
- Ask your school IT contact to confirm your account has access to Haldor.
Website Down
The Haldor website does not load for you.
- Open the page in a private window and on another network.
- Check status.haldor.se for an active incident.
- If only the school network is affected, ask the school IT team to check the firewall.
Teams Integration Issue
Haldor does not open inside Teams, or does not show the classes or assignments that Teams has.
- Check the Haldor app is added to the right Team, and that you are a member of that Team.
- Sign out of Teams and sign back in, then reopen the Haldor tab.
- Check the Teams class matches the class in Haldor. A class that was renamed or recreated can look missing.
- If it still does not appear, ask your school IT contact to check the app permissions for Teams.
Assignments Not Loading
An assignment does not open, or the list is empty for a class.
- Reload the page in a private window with extensions turned off.
- Check the assignment is published for that class and that the class is the right one.
- Check the date range or term filter, since a filter can hide assignments.
- If it fails for everyone in the class, tell the teacher or school IT team the time.
Mobile App Issues
The mobile app does not open, or does not show schedules or results.
- Close the app and open it again, and check the phone has a connection.
- Update the app from your app store.
- Sign out and back in with your school Microsoft account.
- If the website works but the app does not, report it with your phone model and app version.
Slow Performance
Pages are slow, usually at busy times such as the start of a lesson or a test.
- Try again at a quieter time of day.
- Close other tabs and reload the page.
- Use the Teams app or another browser if the page is slow.
- If it is slow for everyone, check the status page and tell the school IT team.
Notification Errors
Notifications about assignments, results or messages do not arrive.
- Check notifications are allowed for the app, or for Teams, on the device.
- Check the notification setting in Haldor or Teams is switched on for that type of alert.
- Check Do Not Disturb or a school schedule is not blocking them.
Still not working?
If it still does not work, contact your school IT contact or your teacher first, since they manage most settings. For a platform-wide problem, contact Haldor through the support option on haldor.se. Have your school name, your role, the class or assignment name, the exact error text, and the time it started with your time zone. Do not send passwords. Live incident updates are on status.haldor.se.
Most school-tool problems come from a Microsoft sign-in, a Teams setting or a class set-up, and they usually clear once that one item is fixed. The status page shows live platform incidents, so you can see whether the problem is outside your school.
