Stellar Toolkit for Outlook 14.0.0.0

Purpose and scope

Stellar Toolkit for Outlook is a bundled suite of seven utilities designed to address a range of mailbox maintenance and recovery tasks for Microsoft Outlook data files. The package is positioned for administrators and power users who manage PST and OST files and need tools for repair, conversion, compaction, splitting, merging, deduplication, undelete recovery, and password recovery. The software targets scenarios involving corrupt or inaccessible data files, oversized PSTs, duplicate mail accumulation, and the need to consolidate or extract mailbox items into alternate formats.

Component overview

The toolkit assembles discrete modules each focused on a particular operation:

• Repair for Outlook — repairs corrupted PST files and reconstructs mailbox data into multiple output formats.
• Converter for OST — converts inaccessible OST files into PST and can extract mailbox items.
• Splitter — divides large PST files into smaller, more manageable parts using various split criteria.
• Compactor — compresses PST files and extracts attachments while preserving links between items and their attachments.
• Merge Mailbox — consolidates mailbox data from multiple PST files into a single PST with duplicate and junk elimination.
• Deduplicator — locates and removes duplicate emails with multiple action options.
• Undelete Email — recovers lost or deleted emails and other mailbox items, including from encrypted PSTs.
• Password Recovery — recovers lost or forgotten passwords for Outlook PST files using multiple master key options.

Key features

The toolkit supports a variety of output formats and export targets. Mailbox items recovered by the repair and conversion utilities can be saved as PST, MSG, EML, RTF, HTML, or PDF. Direct export to cloud and enterprise targets such as Office 365 and Live Exchange is included for certain components. Advanced filtering enables selective inclusion or exclusion of mail items by email address or date range, and filters can omit Junk and Deleted Items folders when saving recovered content.

Functionality details

The repair module is described as capable of parsing severely corrupted PST files and reconstructing mailbox content, including password-protected files. The converter module converts OST files of any size into PST and supports direct export to Office 365 or Live Exchange. Splitting can be performed by size, date, email ID, or folder while maintaining the original folder structure. Compaction removes unnecessary data by extracting attachments to a separate folder and cleaning Deleted Items and Junk Mail folders. Merge functionality collates data from multiple PSTs and offers duplicate and junk removal during consolidation. Deduplication provides several actions for duplicate detection such as delete, move, copy, mark as expired, or flag. The undelete utility recovers emails, attachments, contacts, notes, journals, and tasks, including from encrypted and password-protected PSTs.

Usability and workflow

The toolkit presents a centralized home screen from which each component can be launched. Several components offer drag-and-drop support for selecting PST files, and individual modules provide browse dialogs for file selection. The user manual and installation documents are published and available through the product site for reference. The toolkit is multilingual, offering interfaces in English, German, French, Italian, Spanish, and Japanese.

Technical specifications and system requirements

The product listing specifies Version 13.0.0.0 of the toolkit with a single-system license edition. Installation requires a 64-bit Windows environment; supported operating systems include Windows 11, 10, 8.1, and 8. Minimum memory is listed as 4 GB with 8 GB recommended, and disk space for installation files is indicated as 250 MB. The toolkit provides demonstrable file format support for both PST and OST workflows and includes a free demo with limited functionality to scan and preview recoverable data.

Practical applications

The suite is aimed at situations where mailbox integrity and manageability are priorities. Typical uses include repairing corrupted PSTs to recover mail items and attachments, converting orphaned or inaccessible OST files into PST for portability or archival purposes, and reducing PST size or fragmentation through splitting and compaction. The merge and deduplication features support mailbox consolidation projects and mailbox clean-up tasks where duplicate messages and junk mail contribute to oversized PST files. Password recovery addresses access problems to password-protected PSTs, while the undelete module targets the restoration of accidentally deleted mailbox items.

Formats, export options and filters

Recovered or converted items can be exported in multiple standard formats suitable for archival, legal discovery, or migration. The ability to export directly to Office 365 and Live Exchange for some modules provides integration paths for cloud migration or rehydration of mailbox content. Advanced filters allow selection by sender or date range and provide options to exclude common transient folders during export.

Limitations and scope of functionality

The website notes that the free demo version only provides limited functionality, implying full capabilities require a licensed edition. Some components list actions and options specific to Outlook data file handling; no system-level or network-wide automated deployment details are presented. The product documentation and user manual are available from the vendor site for administrators requiring step-by-step guidance on each utility.

Recognition and documentation

The product page references third-party recognition and includes links to installation, uninstallation, end-user license agreement, and a user guide. The documentation set covers installation and uninstallation procedures and provides a user guide for the Outlook Manager bundle.
