SysInfo PST Converter Tool is a comprehensive solution designed to convert Outlook PST and OST files into multiple file formats and email platforms. It enables individuals, IT administrators, and enterprises to export, migrate, and back up Outlook mailbox data while maintaining email metadata, attachments, and original folder hierarchy. The software works independently without requiring Microsoft Outlook installation and supports both ANSI and UNICODE PST files.
The tool allows users to add single or multiple PST and OST files simultaneously through manual browsing, folder selection, or drag-and-drop functionality. Before conversion, users can preview mailbox contents, including emails, contacts, calendars, tasks, notes, and attachments. Its preview options include Normal View, Browser View, and Attachment View, helping users inspect mailbox information before selecting the required data for export.
SysInfo PST Converter supports multiple output formats, including PST, MBOX, EML, MSG, PDF, CSV, PNG, JSON, DOCX, VCF, ICS, and MD. It also enables direct migration of Outlook mailbox data to Microsoft 365, Google Workspace, Outlook.com, GoDaddy, and other IMAP-compatible email platforms. Users can convert calendars into ICS files and contacts into VCF files for convenient access across different applications.
The software provides advanced filtering options for selective mailbox conversion. Users can choose specific folders, apply date range filters, and remove duplicate emails based on To, From, Subject, BCC, and Body fields. Additional features include attachment management, custom output file naming, folder hierarchy preservation, and the option to skip previously migrated data. These capabilities help maintain organized output and reduce unnecessary duplication during migration.
For managing large mailbox archives, the tool supports splitting resultant PST, MBOX, and PDF files into smaller segments of up to 500 MB and 20 GB, depending on the selected output format. It also provides detailed CSV log reports and real-time migration tracking to monitor conversion activities. Users can preserve attachments separately, merge them, or exclude them according to their requirements.
SysInfo PST Converter is suitable for email migration, local mailbox backup, enterprise cloud transitions, and long-term email archival. It supports multiple Windows versions and offers compatibility with Outlook versions ranging from 97 to 2021, including Microsoft 365. Its modern OAuth 2.0 authentication supports secure cloud migrations.
The free demo version allows users to preview mailbox data and convert up to 50 emails per folder. With Home, Administrator, Technician, and Enterprise editions, the software provides flexible conversion options for different user requirements while prioritizing mailbox data integrity and accessibility.
