Shoviv PST Management Suite

Shoviv PST Management Suite is a technical solution developed for the administration of Microsoft Outlook PST files. The suite operates through automated processes that enable the unification of multiple PST files, segmentation of oversized files, removal of duplicate items, recovery of passwords from protected PST files, as well as compression and storage space optimization. The software architecture supports batch processing, allowing simultaneous execution of operations across an extensive set of files without compromising the structural integrity of the contained data.

• PST Merge. The merge function enables the unification of two or more PST files into a single data container. This process reorganizes the folder structure while preserving the original hierarchy, metadata of items, and properties of each object (emails, contacts, calendars, tasks, and notes). The operation executes in selective fusion mode, where the user designates the primary destination file while secondary files integrate without overwriting existing information.
• PST Split. The split module is engineered to segment PST files that have exceeded recommended operational limits or storage policies. Fragmentation can be performed by size criteria (defining a limit in megabytes for each resulting file), by date range (separating items based on age), or by specific folders. This process maintains referential integrity of items and prevents data corruption during partitioning.
• Duplicate Item Removal. The duplicate analyzer examines PST file contents to identify redundant items based on multiple parameters: subject, sender, sending date, message size, body content, and attachment properties. The tool enables configuration of matching thresholds to differentiate between exact duplicates and close variations. Once identified, duplicate items can be selectively removed, leaving a single reference copy intact within the file.
• PST Password Recovery. The password recovery functionality operates on PST files that have been protected with password encryption in Outlook versions. The module employs recovery techniques that restore access to the file without modifying internal data, preserving the original folder structure and integrity of each stored item. This process does not alter existing security attributes of contained objects.
• PST Compact and Compression. The compaction and compression component performs two complementary operations: compaction eliminates unused or residual space remaining after item deletion, reorganizing the internal file structure; compression applies algorithms to reduce physical disk occupancy while maintaining complete data accessibility. Both operations contribute to reducing the probability of corruption errors associated with oversized PST files.
• Batch Processing Without File Limitations. The suite incorporates a processing engine that supports inclusion of an unlimited number of PST files within a single work queue. Each operation (merge, split, duplicate removal, compression, or password recovery) can be applied simultaneously across multiple files, reducing total administration time and eliminating the need for sequential individual process execution.
• Data Structural Integrity Preservation. Each function within the suite is built with verification mechanisms that ensure preservation of original metadata, unique item identifiers (Entry ID), MAPI properties, attachments in their native format, and hierarchical relationships between folders. Processes execute using working copies or in read-only mode where applicable, preventing uncontrolled modifications to source files.
• Cross-Version PST and Outlook Compatibility. The tool recognizes and processes PST files generated by various Microsoft Outlook versions, including ANSI format (for Outlook versions up to Outlook 2002) and Unicode format (for Outlook 2003 and later). The software automatically handles structural differences between both formats during merge or split operations, ensuring interoperability between files from different eras.
• Advanced Filtering for Data Selection. Each operation can be configured with filters that allow inclusion or exclusion of items based on specific criteria: date ranges, object types (emails, calendars, contacts, tasks, notes, journals), specific folders, senders, or recipients. These filters apply before executing the primary operation, providing granular control over the dataset to be processed.
• Task Scheduling via Command Line Interface. The suite offers support for execution through command line interface (CLI), enabling integration of PST management operations into automated workflows, scheduled maintenance scripts, or centralized management systems. This functionality includes configurable parameters for each operation type, source and destination paths, event logging options, and error handling procedures.
• Detailed Audit Log Generation. During any process execution, the software generates log files documenting each action performed, including processed file names, quantity of items affected per operation, output paths, technical warnings detected, and final status of each task. These logs can be consulted subsequently to verify complete execution of planned processes.
• Selective Migration Between PST Files. The migration functionality enables transfer of specific items from one or more PST files to a destination file, with the option to maintain original folder structure or reorganize according to operator-defined criteria. This process applies in scenarios of mailbox archive consolidation or restructuring of historical email repositories.

The Shoviv PST Management Suite was developed by Shoviv Software Technologies Pvt. Ltd., a company specializing in data management solutions for Microsoft environments and enterprise platforms. Product development commenced in 2016 with the objective of delivering a unified tool that addressed operational limitations present in native PST file administration utilities. The technical implementation was conducted using the C# programming language on the .NET Framework, leveraging low-level access capabilities to MAPI (Messaging Application Programming Interface) storage structures to ensure direct and precise manipulation of PST files without dependency on Microsoft Outlook installation on the processing machine.
