Hi @Ine Hovde
Currently in Microsoft Q&A we only support English, could you please edit your question into English?Thanks for your understanding.
Via translation tool, I got following content. Any misunderstandings, please let me know.
As tag "office-for mac-itpro" focuses more on general issues of Office desktop clients, can you use Microsoft 365 Apps normally?
If not, I suggest you login your account into My Account --- Subscriptions, make sure this account has been assigned with Microsoft 365 Apps license first.
Then you can go to "Apps & devices", click "Install Office" to have a check.
Besides, if this account does not has Admin permission, you can not login it to Microsoft 365 Admin Center, otherwise you will get the message as the one on image.
