Today, Microsoft Outlook is almost like a distant memory and hers disparate and unconnected versions across platforms, they don’t help restore old laurels against webmail clients like Google’s Gmail, which dominates the market.

The company announced on its support page the launch plan and as it replaces other applications such as Mail and Calendar.

The new mail client is based on the Outlook.com web application, but sa redesigned design in the style of Windows 11 aa improved integration with other services such as the Microsoft 365 online productivity suite. In development, Microsoft is adding features and improving its design, adding support for personal Microsoft accounts (@outlook.com addresses), offline support, POP account support, and adding AI that the company will use in all your software.
It will have support for multiple accounts like Gmail and Yahoo! Apart from Microsoft’s own in what is perhaps its biggest advantage over Windows integration, as it allows you to use and switch between them all within a single application.

The new Outlook will be included by default in versions of Windows 11 that Microsoft will release in 2024. The current Mail, Calendar and People apps will be available as a transition in the Microsoft Store, but will be removed for good at the end of next year. .
