I posted a question about Em not downloading all emails off Hotmail.com also, when I go to Em and choose import, Outlook ( first selection ) I cannot tick “Whole Account”, the “Select PST files” stays selected.
Do you have MS Outlook installed on your computer? Can you make a screenshot of the issue? What version of eM Client are you currently using on your computer, can you please check the exact release number in Help > About? Importing accounts only allows you to import your account settings, where as PST import allows you to import all your local data from the data file.
