The SYSessential OLM to PST Converter is a program that safely and correctly changes OLM data into PST format and moves mailboxes. Users can move email messages, calendar entries, contacts, tasks, notes, and attachments from OLM to PST without changing the folder structure of the file. It can change many OLM files to PST format at once, and it works on its own, so you don't need to have Outlook installed to use it.
