Won't import Outlook files

When trying to import my outlook files the program appears to get stuck in a loop with an Outlook pop up requesting permission to access the files and when I click on the yes button the pop up disappears and then reappears and this continues without apparent end and the data is not transferred. Any ideas of the cause and more importantly the solution?

does the problem persist in the latest version of eM Client? If so, please do let me know.
