Recently I am working on a case where Windows Live Mail used for crime conversations. I am a forensic investigator in the United States. So that I can easily import resultant ICS files in various email clients and services accordingly. Now I want to backup Windows Live Mail calendar into ICS (iCalendar) file extension. I am using Windows Live Mail email client from the past few years. Before going to describe the step-by-step process first read, what users actually want? Here I am introducing you a professional technique to backup calendars from WLM WLCalendarStore.edb file to ICS, CSV, Outlook PST, Lotus Notes, Zimbra, Office 365, Exchange Server, Hosted Exchange Server, etc. Do you want to backup Windows Live Mail calendar to multiple standard file extensions? If your response is yes, then don’t be panic.
