MailsDaddy Microsoft 365 Tenant to Tenant Migration

Best Microsoft 365 Tenant to Tenant Migration Tool for Growing Teams

If your company is scaling or going through a merger, you’ll eventually face the challenge of migrating users from one Microsoft 365 tenant to another. We faced this recently when we consolidated multiple business units and had to move nearly 250 mailboxes to a centralized tenant. We used the MailsDaddy Cross-Tenant Migration Service, and the results were excellent.
The tool is cloud-based, secure, and super easy to use. We connected both source and destination tenants using OAuth, mapped users via CSV, and launched a pilot migration before the actual cutover. The dashboard gives you full visibility—every mailbox’s status, migrated data, errors (if any), and logs for auditing.
What makes it even better is the delta migration feature. After we tested and confirmed the trial migration, we simply ran a delta to sync changes and finalize. It also handled OneDrive, calendar items, and shared mailboxes perfectly.
Folder structure, read/unread status, metadata—everything was preserved. Their support team is also extremely responsive and guided us in real-time.
For any business planning a Microsoft 365 consolidation or restructure, this service is a must.
