SysTools IMAP Migration Tool

SysTools IMAP Migration Tool is an enterprise-grade desktop application designed to securely automate email transfers between any two IMAP-enabled servers. The Problem It Solves Switching email service providers, merging domains, or onboarding new employees often requires moving massive amounts of email data. Doing this manually using desktop clients (like Outlook or Thunderbird) is incredibly slow, frequently results in lost data, destroys folder hierarchies, and causes costly downtime for businesses. The Solution Our tool eliminates the friction of email migration. Available for both Mac and Windows, it allows IT admins and individuals to execute bulk, direct server-to-server migrations between platforms like Gmail, Office 365, Yahoo, Zoho, and custom webmail—without any data loss or downtime. How It Works Authenticate: Log into your Source and Destination IMAP accounts directly within the software. For bulk enterprise migrations, you can map multiple user accounts simultaneously using a CSV file. Filter & Select: Choose specific folders to migrate, or apply Date-Range filters to only move emails from a specific timeframe. Migrate: The software securely transfers your data while preserving the exact folder hierarchy, metadata, and read/unread status of every email. Key Features: Concurrent Migration: Migrate multiple user accounts at the same time to speed up enterprise transfers. Delta Migration: Run a secondary migration that only transfers newly arrived emails, skipping duplicates of previously migrated data. Maintains Integrity: Keeps attachments, header details (To, CC, BCC), and folder structures completely intact. Cross-Platform: Fully compatible with the latest versions of Windows OS and macOS.
