Export email, calendars, contacts and more from Outlook OST

Email information not only contains messages but also contacts, calendars, folders and files. Calendar entries are useful to set up meetings, plan for a particular task, and set dates for important events. Contact information contains data about the contacts you frequently communicate with. Exporting OST to PST file can have plenty of reasons such as moving from one email account to another, changing the Outlook versions, for periodic backup of important contacts and so forth. For OST to PST conversion, it is therefore important that all the contacts, calendar, tasks, journals are migrated along with the emails. See OST vs PST
