Office 365 server to Server Migration with EdbMails

Migrating mailboxes between Office 365 servers involves more than just moving data. It requires a strategy that ensures continuity, minimizes downtime, and aligns with Microsoft’s throttling policies and authentication protocols.

This process uses secure API-based communication to transfer mailboxes directly between tenants without manual data exports. It supports full-fidelity migration including emails, folders, permissions, and mailbox properties. Administrators must handle token-based authentication, manage user mapping, and maintain compliance throughout the operation.
