EdbMails IMAP Migration Tool vs Inbox Hop

EdbMails IMAP Migration Tool moves email and folders between IMAP servers, and supports transfers from IMAP to Office 365, Exchange Server or PST, as well as PST to IMAP. The Windows software lists providers including Gmail, GoDaddy, Rackspace, Zoho, Zimbra, IceWarp, cPanel, Yahoo Mail and Outlook.com. Users can choose folders and subfolders and filter mail by date, sender, attachments and AND/OR conditions. The maker says it preserves metadata, headers, folder structure, formatting and language encoding. Multiple mailboxes can be loaded from CSV, and separate installations can run migrations in parallel. Outlook is not required for IMAP-to-IMAP migration or Exchange-to-Office 365 moves. The maker says data and credentials are not stored on its servers and lists OAuth 2.0, TLS, AES 256-bit encryption for locally stored incremental-migration metadata and MFA support. A free trial is available, limited to 30 items from each folder. One-time plans cost 200.00 USD for 100 mailboxes, 299.00 USD for 1000 mailboxes, or 499.00 USD for unlimited mailboxes.

Inbox Hop migrates email, calendars, and contacts among Microsoft 365, Google Workspace, and on-premises Exchange. Projects can move data cloud-to-cloud, from cloud to on-premises, or in the reverse direction. Microsoft 365 connections use Exchange Web Services with guided Azure app registration and permission checks. Google Workspace uses Google APIs and service-account domain-wide delegation, avoiding per-mailbox credentials. After scanning, the platform suggests mailbox matches; users can change assignments or create missing destination mailboxes automatically. Run modes include scanning, folder-structure-only copies, full migrations, and incremental delta runs. A full migration consumes one prepaid credit per mailbox regardless of data volume, while scans and delta runs use no credits. On-premises Exchange can connect directly over HTTPS or through a Windows connector that polls outbound HTTPS without inbound firewall rules. Monitoring shows transfer rate, items per minute, health, and chronological logs. Inbox Hop describes encrypted connection secrets, tenant isolation, role separation, permission validation, and append-only audit records. It is intended for organizations changing mail platforms.
