Microsoft is mandatorily migrating worldwide business end users of the classic Outlook client to the new Outlook version starting April 2026. The tech giant wants to introduce as many end users as possible to the client’s new interesting features.
Microsoft announced that, starting in April 2026, Microsoft 365 for Enterprise users who are still using the “classic” version of the Outlook client will be forcibly migrated to the new version for Windows.
However, after this forced migration, the specific end users affected will be given the option to return to the familiar old classic Outlook environment.
Increased focus on new Outlook
The reason for the announced forced migration to the new client is that Microsoft would also like to introduce business Microsoft 365 end users to the improved client’s new features. Meanwhile, many Outlook end users, including consumers, have already moved to the new client.
The new client’s features include integrating Copilot functionality, new themes, and time-saving tools such as pinning and mail snoozing.
Migration process and exceptions
According to Microsoft, the April 2026 migration process follows completely automatically. Before the migration, end users will be notified that they are being converted. In doing so, they will be given an opt-out option to avoid this migration.
In addition, end users will not be converted to the new Outlook version if the turnover button is hidden via policies, a perpetual license is used, or the account is an on-premises account.
However, the migration policy will be available in Microsoft Group Policy Objects (GPO), Cloud Policy, and Intune at a later date.
