Sikker mail (secure email) means that the email you send is encrypted and signed. Sikker mail is intended for sending emails which contain confidential information and sensitive personal data. The encryption ensures that only the recipient can read the email. If the email ends up in the wrong hands, it will be unreadable. The signature ensures that the sender is the person he/she claims to be, and that the content is the same as when it left the sender.

This method is relevant for people who need to send secure emails from time to time. This solution makes it possible for you to send secure emails from your personal mailbox.

How to send a secure email from your own mailbox:

1. Click ‘Ny mail’ (new email) and write your email as usual.
2. Click ‘Send Sikkert’ (send securely) when you want to send the email. If the recipient also has a secure email solution, the email will be sent securely and any responses will also be sent securely back to your inbox. If the recipient does not have a secure email solution, go to step 3.
   
   
   
   
   
3. If the recipient does not have a secure email solution, you must add the recipient’s mobile phone number in the ‘Mobilnummer’ field and click ‘OK’. The email will then be sent to a secure location on a server.
   
   
   
   

4.  The recipient will now receive an SMS code and an email with a link which can be used to read the email. The recipient can respond securely to the email and can add files to the email response.

If the people in your unit need to send secure emails frequently or more people work together and need to send secure emails, we recommend that you use a shared mailbox with a security certificate. You can use this shared mailbox to send and receive secure emails. It will also be possible for each person to send secure emails from his/her personal mailbox.

Your local IT support team can help set up a shared mailbox with a security certificate.  

How to send a secure email from a shared mailbox:

1. Click ‘Ny mail’ (new email) and write your email as usual.
