• Addition of multiple OLM files without size limitations. The software permits the simultaneous selection and loading of multiple OLM files regardless of individual or combined file sizes. This capability streamlines the processing of large data volumes distributed across different OLM files, eliminating the requirement to execute separate conversion operations and ensuring all items are managed within a single workflow.
• Conversion to PST, EML, MSG, HTML, ICS, and vCard formats. Beyond the native Microsoft Outlook PST format, the tool provides options to export data into individual file formats such as EML, MSG, HTML, ICS for calendar entries, and vCard for contacts. This variety of output formats enables utilization of converted data across different email clients, document management systems, and calendaring applications without dependency on the Outlook ecosystem alone.
• Preservation of folder hierarchy and original properties. Throughout the conversion process, the tool maintains the complete folder structure from the source OLM file, including nested subfolders and all item properties such as metadata, timestamps, read status, and other attributes. The resulting output accurately reflects the organization and integrity of the data as it existed within the original Mac Outlook profile.
• Direct export to Office 365 and on-premises Exchange Server. The utility extends beyond local file generation by enabling direct migration of OLM data to Exchange Online mailboxes (Office 365) or on-premises Exchange servers. During this process, mailbox mapping, filter application, and folder correspondence between source and destination mailboxes can be configured.
• Resultant PST file size control. Users can define a maximum size threshold for generated PST files. When the extracted data exceeds the specified limit, the tool automatically splits the output into multiple PST files. This functionality facilitates management of large data sets and prevents performance issues or corruption risks associated with PST files exceeding Microsoft's recommended size guidelines.
• Incremental export (delta migration) facility. The incremental export feature allows the process to resume from the point of interruption in cases of cancellation, network failure, or power loss. Upon resumption, the software identifies previously transferred items and prevents duplication within the destination, reducing processing time for operations requiring continuity across multiple sessions.
• Filtering by folder criteria and date range. Users can select specific folders from the OLM file for inclusion or exclusion during conversion, and define a date range to restrict processed items. These filtering mechanisms enable extraction of only relevant data, reducing output size and optimizing execution duration.
• Compatibility with all Windows versions and modern file systems. The application operates across Windows environments from earlier versions through the latest releases, with support for NTFS and ReFS file systems. This compatibility ensures that OLM files can be processed on standard workstations, servers, or virtual machines without additional configuration requirements.
• Free demo version with processing limitation. A trial edition is distributed that allows processing of up to the first fifty items per folder. This version provides access to all features including filters, output formats, and Exchange export, with the sole restriction being the quantity of data processed, enabling evaluation of conversion accuracy and performance prior to purchase.
• Selective conversion through item inclusion and exclusion options. The software incorporates mechanisms to designate specific folders or item types such as emails, contacts, calendars, tasks, and notes for conversion. This granularity permits generation of PST files or alternative formats containing exclusively the required information, avoiding migration of redundant or unnecessary data.

Shoviv OLM Converter is developed by Shoviv Software Private Limited, a company specializing in migration and conversion utilities for messaging and collaboration platforms. Development of this tool began in 2015, initially focusing on OST to PST conversion and subsequently extending to OLM file handling to address requirements in hybrid environments combining Mac Outlook and Windows Outlook deployments.
