OLM To PST Converter Pro - AppE is designed to convert OLM (Outlook:mac 2011 archive export) files to PST files.
Outlook:mac 2011 saves its data (including e-mails, contacts, calendars, account info, etc.) to a confidential database. The program doesn’t grant full access to it, but lets users export mail, calendar, and contacts data into a portable file with .olm extension. Meanwhile, this file is an archive which contains all your above-mentioned personal information.
