OLM Converter Pro – AppEd is a tool which allows users to switch their email application without losing any of their important data. Email conversations, as well as contact details and events in your calendar, can all be migrated easily from Outlook:mac 2011 accounts.

Convert emails, contacts, and calendars

This app has been designed to convert Outlook accounts to Apple Mail with as little hassle as possible. Each folder’s hierarchical structure is supposed to be migrated as it currently stands although some more complex structures need to be checked to make sure the process has been successful. Attachments are preserved after a migration has been carried out, too. Address Book, iCal, Microsoft Entourage, Mozilla Thunderbird and Postbox are all supported along with other popular email software applications.

A useful conversion tool?

Because it does away with slow and often awkward Windows or Java-based systems, the OLM file conversion process used in this app is speedy. The program is not really for general users, however. It comes into its own only if you have hundreds of contacts you'd need to export in order to change email service.
