Good news for users of Microsoft's classic Outlook application. Microsoft won't deprecate the classic Outlook version until at least 2029.

The new Outlook for Windows has been released as a preview some time ago. When Microsoft released it, it confirmed that this new app would replace the Mail and Calendar app on Windows systems and also the classic Outlook application.

While Microsoft did publish a schedule for the deprecation of Mail and Calendar, it did not do so for the classic Outlook for Windows application.

The company has finally lifted the veil on the future of the classic version of Outlook and the migration to the new Outlook version. In short, Outlook users may use the classic Outlook for Windows until at least 2029 according to Microsoft.

This allows customers, home and commercial, to opt-in to using the new Outlook app. The app itself is not enabled by default and users need to enable it explicitly through the "try the new Outlook" toggle in the classic Outlook app.

Toggling is also available in the new app to go back to the classic app at any time during the opt in stage. A feedback form is displayed each time users go back to the classic Outlook application.

The new Outlook application receives the general availability milestone during this stage. This moves it out of preview. Customers may get "regular and assisted technical support" from this moment on.

The second stage moves from opt-in to opt-out. This makes the new Outlook application the default on Windows systems. Microsoft promises that it will provide at least 12 months' notice before this happens in production environments.

Outlook users may still go back to the classic Outlook application during the opt-out stage.
