I would like to suggest a Tool that will help users to perform OLM to PST conversion easily without hassle. The best thing about the tool is it also gives multiple saving options. So, you can also save OLM mailboxes to PST, PDF, EML, MSG, EMLX, HTML, MHT, RTF, XPS, Lotus Notes, and Zimbra. It guarantees 100% data safety and assures no data loss or file modification.
