explanation for non-techies**

Starting in early 2026, Microsoft Outlook for Windows will introduce a feature that automatically displays automapped calendars when users switch from the classic version to the new Outlook. Previously, users had to manually access these calendars, but with this update, the process will become seamless and require no additional steps from the user.

Think of it like upgrading from a manual car to an automatic one. In a manual car, you have to change gears yourself, which requires more effort and attention. With an automatic car, the vehicle does the gear-changing for you, making the driving experience smoother and less demanding. Similarly, the new Outlook will handle the task of displaying automapped calendars automatically, saving users time and effort.

This change will roll out without needing any action from administrators, and it will be enabled by default. Users will find that when they switch to the new Outlook, their automapped calendars will be readily available, much like how an automatic car seamlessly shifts gears without the driver needing to intervene.

Organizations might want to inform their users about this upcoming change and update any relevant guides or documentation to reflect the new process. This will ensure that everyone is aware of the improved functionality and can take full advantage of the new feature once it becomes available.
