Key Features Of PST Merge Tool

Merge Unlimited PST Files

DRS Softech PST Merge Tool allows you to merge any number of PST files without size limitations. Whether you have dozens or hundreds of PSTs, this tool handles them with ease, ensuring quick and accurate merging.

Supports Both ANSI & UNICODE PST

It supports merging of both ANSI (older format) and UNICODE (newer format) PST files. This makes it ideal for users migrating from older versions of Outlook to newer ones.

Three Merge Options:

• Merge PST Files into One: Combine all folders (Inbox, Sent, Contacts, etc.) into a unified PST file.

• Join PST Files: Adds all PSTs as separate folders within a single PST file, preserving folder hierarchy.

• Merge Specific Folders: Merge only specific folders like Inbox or Contacts across multiple files, avoiding duplication or clutter.

Remove Duplicate Items

To keep your PST file optimized and clutter-free, the tool includes a powerful deduplication feature that identifies and removes identical items during the merging process.

Preserve Metadata & Folder Hierarchy

DRS Softech PST Merge Tool ensures that original folder structures, email metadata (To, From, CC, BCC, Subject, etc.), read/unread status, and attachments are retained accurately after merging.

Password-Protected & Corrupt PST Support

It can merge password-protected PST files (if the password is known) and even supports slightly corrupted PST files. This makes it highly versatile for recovery and archival purposes.

Outlook Compatibility

The tool supports all versions of Microsoft Outlook, including Outlook 2021, 2019, 2016, 2013, 2010, 2007, and earlier. It works smoothly with PST files created in any version of Outlook.

Intuitive GUI for Easy Navigation

Even users with minimal technical knowledge can operate the tool efficiently thanks to its clean, intuitive, and interactive interface. The step-by-step wizard makes merging PSTs a simple and stress-free task.

Fast & Secure Processing

Built with an advanced merging algorithm, the software processes large PSTs quickly while maintaining 100% data security. No data is stored or leaked during the operation.
