Aryson PST Merge: Complete Guide to Combining Multiple PST Files

Combining multiple Outlook PST files into one consolidated file can simplify mailbox management, free up storage, and make backups easier. This guide walks through using Aryson PST Merge to merge PST files safely and efficiently, covering preparation, step-by-step instructions, common options, troubleshooting, and best practices.

What Aryson PST Merge does

• Purpose: Combines multiple Outlook PST files into a single PST without modifying source files.
• Supported items: Emails, contacts, calendars, tasks, notes, and journal entries (depending on PST content).
• Use cases: Mailbox consolidation, archiving, migration, and removing duplicate PSTs.

Before you begin

• Backup: Create copies of all original PST files before merging.
• Outlook closed: Close Microsoft Outlook during the merge to avoid file locks.
• Disk space: Ensure enough free disk space equal to the sum of input PST sizes plus some buffer.
• Compatibility: Confirm Aryson PST Merge supports the PST types you have (ANSI vs. Unicode) and your Outlook version.

Step-by-step: Merge PST files with Aryson PST Merge

1. Install and launch

   • Download and install Aryson PST Merge from the official site. Open the application.

2. Add PST files

   • Click the “Add File(s)” or “Add Folder” button.
   • Select the PST files you want to merge. You can add multiple files at once.

3. Choose merge mode

   • Merge into a single PST: All selected PSTs combined into one output file.
   • Merge by folder: Combine corresponding folders across PSTs (e.g., all Inboxes together).
   • Join PST files: Append PSTs one after another without merging folder hierarchies.
   • Select the mode that fits your goal.

4. Select items and filters (optional)

   • Choose specific mailboxes or folders to include.
   • Apply filters by date range, sender, subject, or item type to limit merged content.
   • Enable or disable inclusion of deleted items or empty folders.

5. Handle duplicates

   • Choose duplicate handling: Skip duplicates, Merge duplicates, or Create separate entries.
   • Review duplicate settings to avoid unwanted data loss.

6. Configure output

   • Set the destination path and provide a filename for the merged PST.
   • Choose output PST format if the tool offers options (Unicode recommended for large mailboxes).

7. Start merge

   • Click “Merge” or “Start.” Monitor progress; the app will show status and estimated time.
   • Wait until the process completes. Do not interrupt unless necessary.

8. Verify result

   • Open the merged PST in Outlook (File → Open & Export → Open Outlook Data File).
   • Check folder structure and important items. Verify no expected data is missing.

Common options and features

• Preview pane: View items before merging.
• Search within PSTs: Find specific messages to include/exclude.
• Split output PST: Break a large merged PST into smaller files by size.
• Password handling: If PSTs are password-protected, the tool may prompt for passwords or support password recovery.
• Log/report: Generate a merge report showing processed files and any errors.

Troubleshooting

• PST file locked: Ensure Outlook and other apps are closed. Check file permissions.
• Merge fails or crashes: Reboot, run the tool as Administrator, and retry. Check for corrupted PSTs—use ScanPST to repair if needed.
• Missing items: Confirm filters weren’t excluding content. Re-run merge on specific PSTs to isolate issues.
• Large PST size limits: Use Unicode output or split output into smaller PSTs if Outlook version has size constraints.

Best practices

• Maintain backups of originals until you confirm the merged PST is correct.
• Merge incrementally when working with very large data sets—test with a subset first.
• Keep a consistent folder structure beforehand to minimize clutter.
• Use filters to exclude spam, duplicates, and irrelevant historical items.
• Document which PSTs were merged and when for future reference.

Alternatives and when to choose them

• Use Outlook Archive or Export features for simple consolidation without third-party tools.
• Consider enterprise migration tools (e.g., for Exchange/365 migrations) when moving mailboxes between servers.
• Choose Aryson PST Merge when you need a dedicated, GUI-driven solution with flexible merging modes and duplicate handling.

Aryson PST Merge provides a straightforward way to consolidate multiple PST files into one, with options for folder-based merging, duplicate handling, filters, and output configuration.
