I just finished a challenging Microsoft 365 rebranding project that involved migrating hundreds of user accounts from one tenant to another. Trust me, it’s not something you want to do manually. After a lot of research and some trials, we settled on the MailsDaddy Cross-Tenant Migration Service—and it was one of the best IT decisions we made.

The service is cloud-based, fast, and completely secure. It handled mailboxes, OneDrive data, and even archive mailboxes without any data loss. We could apply filters, schedule the migration, and get detailed logs for compliance. The delta migration feature was especially useful when syncing last-minute changes.

Support was outstanding—they assisted us during setup, testing, and even post-migration clean-up. Whether you're a system admin or consultant managing a migration project, this tool can save you time, money, and stress.
