Spec score 7.2 #18 of 25 in Email Migration Software

What it is

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.
