CodeTwo Office 365 Migration review
A Windows-focused migration tool for complex Microsoft 365 mailbox moves.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
CodeTwo Office 365 Migration is a Windows desktop application for organizations and administrators moving mailbox data to Microsoft 365. It supports migrations from on-premises and hosted Exchange, Google Workspace and other IMAP servers, as well as separate Microsoft 365 tenants. The scope extends beyond email: Exchange and Microsoft 365 migrations can include contacts, calendars, tasks, notes, journals, archive mailboxes and public folders where supported. It is intended for teams that want to manage mailbox migration without third-party data processing.
Its strongest fit is complex or staged Microsoft 365 work. The feature set covers cutover, staged and hybrid migrations, mailbox matching, automatic target mailbox creation, scheduled migration jobs, filtering, delta migrations and migration reports. These controls give administrators options for planning an incremental move, repeating changes after an initial transfer and reviewing migration progress. Google Workspace and other IMAP sources are supported, but the published scope distinguishes them from Exchange and Microsoft 365: IMAP migrations cover email folders, while contacts and calendars are supported for Exchange and Microsoft 365 migrations.
The licensing model is based on a one-off new license, with technical support included for one year. Additional mailbox licenses are available, with the price depending on the number of licenses. A 30-day trial provides time to assess the migration workflow before purchase, while the Windows-only platform limits its suitability for teams that administer migrations from macOS or other operating systems. Choose CodeTwo Office 365 Migration when broad Microsoft 365 migration modes, mailbox data coverage and administrative controls matter. Consider another option if you need a cross-platform application, a free plan or richer IMAP data migration beyond email folders.
