I want to share with you another amazing tool called CubexSoft OLM to PST Converter, which easily converts several OLM files at once into PST format. During the whole conversion process, there is no data loss. It has a straightforward user interface (GUI) and many fantastic features for simple conversion. All Outlook, Windows, and Mac OS editions are compatible with it. Additionally, the first 25 items in each folder can be saved for free when using the demo version.
