How can I import the .nk2 file from outlook to eM Client?

I changed from outlook to eM Client. It was no problem to import email data etc. But I also want to import the autocomplete email adesses data from outlook to eM client. This is no problem from outlook to outlook e.g. when you install a new computer. The outlook file is an .nk2 file. I already saved this file at an usb stick, but I either do not find any import function at eM Client nor any hint where to implement the .nk2 file manually. Can anybody help me?

Hello Jo,
unfortunately we do not support import from .nk2 files.
I suggest either saving the information as CSV instead if your version of Outlook supports it or use an online tool to convert the nk2 file to csv.
Then you can import these as contacts into eM Client.
