Mailbox Migration for Businesses
Questions (FAQ)
What is a mailbox migration tool?
A mailbox migration tool is a software solution that helps transfer emails, contacts, calendars, and other mailbox data from one email system to another. It ensures a smooth, secure, and automated migration process, minimizing downtime and data loss.
Why do businesses use a mailbox migration tool?
Businesses use mailbox migration tools to move from legacy systems (like Exchange on-premises or Lotus Notes) to modern cloud platforms such as Microsoft 365 or Google Workspace. These tools streamline the process, reduce manual work, and maintain data consistency during the transition.
What is the difference between a mailbox migration tool and manual migration?
Manual migration often requires exporting and importing PST files or using scripts, which can be time-consuming and error-prone. A mailbox migration tool automates this process, managing permissions, folder mapping, throttling, and large-scale transfers with minimal user intervention.
How does a cloud-to-cloud mailbox migration work?
Cloud-to-cloud migration connects directly to both source and destination environments through secure APIs or protocols (IMAP, EWS, or Graph API). The tool then transfers mailbox data in batches, preserving structure, labels, and metadata for a seamless transition.
Is mailbox migration secure?
Yes. Cloudiway’s Mailbox Migration Tool uses end-to-end encryption and OAuth 2.0 authentication to ensure data privacy. No emails are stored during migration, and all transfers are fully compliant with industry standards like GDPR.
What are the main challenges of mailbox migration?
Common challenges include throttling limits, data volume, coexistence between systems, and preserving permissions or shared mailboxes. A professional tool like Cloudiway’s platform helps you overcome these issues with smart connectors and advanced error handling.

We have been working with Microsoft 365 for more than 10 years. We have needed to perform Cloud-to-Cloud migrations on many occasions. Cloudiway has always been the perfect partner providing a very valuable product and support”

All was achieved 24h after the start, 1st time in my career after more than 10 years of migration. Cloudiway takes care of everything, Mail/shared mailboxes/Ressources/Teams/OneDrive, etc. You need one hour of consulting services to be sure everything is well set up before starting, but in a migration budget, this hour is nothing regarding the time you earn after in support issues…
