I have forgotten my password to post.au.dk, what do I do?

Access your mailbox in post.au.dk with your username and password to mitstudie.au.dk (Self-service). If you have forgotten your password, please go to https://adgang.au.dk/en 

If you are unable to access your AU email and have not linked a private email address to your au email, you can go to mit.au.dk and log in with WAYF and NemID to change your password.

Can I get another email address?

On mit.au.dk (Self-service) and E-mail addresses you can find your email addresses:

  • studentID@post.au.dk
  • firstname.(middlename.)lastname@post.au.dk

Go to Create alias to change your email name (before @). All former email alias will be deleted in order to others to be able to use them.

What is the size of my mailbox?

You have unlimited space in your mailbox. However, there is a limit of 50 MB when you attach files.

Please be aware that some types of files (e.g. images) take up more space when they are attached so the practical limit is 40-45 MB.


What happens to my email when I no longer study at AU?

  • For an unspecified period of time, you keep your post.au.dk email address and can continue to log on e.g. through http://mitstudie.au.dk.
  • If you do not remember your password, you can order a new password at https://adgang.au.dk/en. The new password will be sent to the email address we might have on you. You can also log on to mit.au.dk (Self-service) using NemID. (Click ‘WAYF-login’ and select ‘NemID’ as your institution).
  • If you do not remember your password and if you cannot use NemID, it is not possible to access your email.
