Understand OLM and PST File Formats OLM and PST are two different mailbox file formats used by Outlook on different operating systems. OLM files are mainly associated with Outlook for Mac, while PST files are commonly used by Outlook for Windows. When users move mailbox data between Mac and Windows environments, converting OLM to PST becomes necessary. The conversion process can include emails, contacts, calendars, tasks, notes, folders, and attachments. https://www.vartikasoftware.co....m/product/olm-to-pst

Preserve Emails, Attachments, and Mailbox Structure -During OLM to PST conversion, preserving mailbox data is an important requirement. The conversion process can transfer emails along with their attachments, sender and recipient details, subject lines, dates, formatting, and folder organization. Contacts, calendars, tasks, and notes can also be included when supported. Maintaining the original hierarchy helps users access converted information in an organized manner after opening the resulting PST file in Microsoft Outlook.
