I cannot export Mac Outlook 2011 mails and folders from my old Mac to another computer (Mac). The file (olm) is incomplete and great part of emails are missing. The exportr app releases a file where it represents errors during exporting (2015-06-17 15:58:50: Error writing attachment to archive "/Users/albertoforesti/Documents/agenda/Archivio di Outlook per Mac.olm".2015-06-17 15:58:50: Error writing attachment to archive "/Users/albertoforesti/Documents/agenda/Archivio di Outlook per Mac.olm".2015-06-17 15:58:50: Error exporting folder 'Sul mio computer/Posta in arrivo'. ).

Is there anyone in condition to solve or advice?

thank you in advance
