Enterprise-Grade Email Migration Tool

Everything You Need to Perform Efficient Email Migrations Across Platforms While Maintaining Complete Mailbox Integrity

Zero Downtime Migration

Ensure uninterrupted communication throughout the entire migration process. The cloud migration tool performs migrations in the background while users continue accessing their mailboxes without disruption.

Modern OAuth 2.0 Security

Authenticate securely without exposing user credentials. The email migration tool supports modern OAuth authentication for Microsoft 365 and Google Workspace. This ensures secure authorisation through trusted identity providers and protects mailbox data during the migration process.

Complete Mailbox Migration

Migrate entire mailboxes, including emails, contacts, calendars, attachments, folders, and metadata, without losing data integrity or mailbox structure. Ensures complete and reliable mailbox transfer.

Selective Workload Transfer

Choose specific mailbox components such as emails, contacts, and calendars to customise your migration scope and minimize the time of mailbox migration.

Smart Migration Filters

Use advanced filtering options to migrate only the data you need based on date range, folder selection, or user accounts. Moreover, use the Delta migration option to move only newly arrived data, without restarting the entire migration, while ensuring previously migrated data remains unchanged.

Detailed Migration Reports

After migration completes, it generates two reports, i.e. summary (includes an overview of the procedure) and a detailed CSV report (showing every migrated email, item, and file).

We recently used ExpressMigrator Email Migration Tool during a tenant consolidation project involving more than 1200+ mailboxes. The software handled mailbox transfers with minimal intervention, and we were able to monitor the progress clearly through the reporting dashboard. Its bulk migration option will help to complete the entire migration in the expected time. My team and I are very happy with its fast performance.
