MailsDaddy Office 365 Tenant to Tenant Migration

We recently completed a full Microsoft 365 tenant migration as part of a company rebranding. This included moving mailboxes, shared folders, calendar items, and OneDrive documents for over 300 users. After reviewing several solutions, we trusted MailsDaddy Cross-Tenant Migration Service, and it was an excellent decision. What makes this tool ideal for projects like ours is how easy and fast it makes a complex job. We authenticated both tenants securely, mapped users, and kicked off pilot testing all within the first few hours. The dashboard provides real-time migration tracking, and logs are detailed enough to meet internal compliance standards. We migrated mailboxes in phases, using the delta migration feature to avoid transferring the same data twice. It also preserved folder structure, calendar invites, mailbox permissions, and metadata during the process. The tool is web-based, meaning no hardware or software burden. Their support team helped us with planning, testing, and even adjusting timelines during the live migration window. If you're planning a migration due to brand changes, mergers, or IT restructuring, give this service serious consideration. It worked flawlessly for us. You can download the software or use our services to Tenant to Tenant migration.
