After several issues with various apps, Microsoft aims to impress again with improvements. A comprehensive update for Outlook is planned for May 2026, primarily to simplify operation and enhance everyday usability. The focus is on a new generation of apps and features that will structure calendars and inboxes more efficiently.
Recently, Microsoft has drawn attention mainly due to technical difficulties. For instance, iPhone users had to intervene after an Outlook outage, while a Samsung update reportedly affected several Microsoft applications. Such disruptions are particularly problematic for a company whose programs are used by millions daily. Now, the company is banking on new features to create positive momentum again.
New Outlook App Comes into Focus
According to entries in the Microsoft 365 roadmap, the company is working on several innovations for Outlook. These are intended to ease the transition to the new Outlook app and make overall use more straightforward. At the center is the new Outlook for Windows, a modern, web-based application that aligns more closely with the browser version.
Microsoft plans to establish this version as a long-term replacement for the classic Outlook application from the Office suite. The existing Windows apps Mail and Calendar will also be gradually replaced by the new solution. In current installations, the new app is already offered as an alternative, and on new devices, it is partially pre-installed.

Improvements for Calendar and Inbox
A key focus of the update is on calendar management. Microsoft intends to add features that were previously missing. These include automatically assigned calendars, which will also be visible in the new Outlook. Additionally, calendars from colleagues can be displayed directly in the left navigation bar upon request. This is particularly helpful for users who work with private, professional, and shared calendars simultaneously.
Moreover, multiple calendars can be shown or hidden within groups simultaneously. Appointments can also be opened, copied, deleted, or categorized in bulk. These functions are designed to simplify scheduling coordination.
New sorting options are also planned for the inbox. Flagged emails can be sorted by flag status and by start and due dates. Users who organize their tasks with flags will be able to find important messages more quickly. In the web version, it is also planned to save appointments as ICS files to facilitate forwarding or integration into other calendar programs.

Classic Outlook Version Also Expanded
Despite the clear focus on the new app, the classic desktop version of Outlook is also receiving additional features. The AI assistant Copilot will be more integrated there. Users will be able to highlight text in emails and request additional information or summaries.
This means the classic Outlook application remains part of the update strategy for now, even as Microsoft increasingly shifts its focus to the new app.
