Q&A – Transition to Altinn Version 3 for Receiving Digital Sick Leave Notices and Sending Follow-up Plans

Q: Was the email we received spam?
A: No. This was not spam. The email was sent to inform you that an action is required to enable Altinn version 3.

Q: Why did we receive an email about the transition to Altinn’s new functionality?
A: The email was sent to all users with the System Administrator role in your Simployer portal, as well as customers who have the Sick Leave Follow-up module.

Q: Is this something Simployer has initiated?
A: No. This change is driven by Altinn. Altinn has introduced improvements that require us, and consequently you as a customer, to adopt the new solution.

Q: When will the old enterprise certificate stop working?
A: Altinn will disable the old solution for submitting follow-up plans on 16 February 2026. Receiving digital sick leave notices will continue to work for a limited period after this date.

Q: What happens if we are unable to complete this before the deadline?
A: If the setup is not completed by the deadline, you will not be able to send follow-up plans until the new solution is activated. Receiving digital sick leave notices will continue for a short period until the setup is completed.

Q: Why did we receive this email if we do not have the Sick Leave Follow-up module?
A: The email was sent to all users with the System Administrator role in Simployer, in addition to customers who have the Sick Leave Follow-up module.

Q: We are using a BETA version of the new Altinn. The interface looks different and we cannot complete the setup.
A: Please use the button in the lower-left corner labeled “Switch to old Altinn” and continue the process there.

Q: We have followed the instructions but receive error messages. What should we do?
A: Unfortunately, there was an issue in the solution when it was first released, but this has now been resolved. If you are still experiencing errors, please contact us.

Q: Do we need to configure both Digital Sick Leave Notices and Follow-up Plans?
A: Yes, both configurations must be completed.

Q: We have multiple legal entities. Do we need to complete this per legal entity?
A: Yes. The setup must be completed separately for each legal entity.

Q: We have completed the steps and received approval in Altinn, but Simployer still shows that it is not configured. When we click “Configure,” we receive an error message.
A: This is due to the page not being updated yet in Simployer. As long as you have clicked the Approve button in the Altinn window, everything is in order.

Q: When we follow the link, we see a message stating “No companies found.”
A: This usually means that your organization number or business number is missing from the organizational structure, or that you have not previously been connected to the Altinn integration.

Q: Does the Managing Director need an active user in Simployer to perform the update?
A: Yes, the Managing Director must have an active Simployer user, but no specific roles are required.

Q: Can anyone other than the Managing Director perform the update in Altinn?
A: For configuring follow-up plans, users with the role Programming Interface (API) can also complete the setup.

Q: We previously only sent follow-up plans and did not receive digital sick leave notices in Simployer. Will we now be able to receive them?
A: Yes. If you previously had an enterprise certificate and used one of the services, you will now be able to use both.

Q: We register absence in Capitech Flow. Will this result in sick leave notices being sent directly to Flow?
A: No. Sick leave notices will not be sent to Capitech Flow.

Q: We cannot see that the follow-up plan is confirmed; it still shows as “Not configured.”
A: Go to step 15 in the guide and click Test. The status should then turn green.
