Import .olm and create file

Hello, I have just purchased Em client but I am unable to import an .Olm file and I see that we cannot create folders to file my emails.
Can you help me?

You can import the file by going to Menu (menu bar on Mac) > File > Import > Outlook for Mac (olm)

To create a folder to save messages other than in the Inbox, right-click on the Inbox folder and choose New Folder.

i have a lot o pb like this and often this message?
and sorry but i can t create files.
