Microsoft is updating its New Outlook interface to provide greater clarity when sorting email messages. According to the Microsoft 365 Roadmap (ID 564803), the platform will automatically display the specific column being used for sorting, making it easier for users to understand the organization of their inbox. This update is scheduled for general availability starting in June 2026.
How the New Outlook Sorting Update Works
Currently, users can sort emails in Outlook for Windows and Outlook on the web using various criteria, such as sender, category, importance, subject, and message size. When the upcoming change arrives, selecting a sort field other than the standard “From,” “Subject,” or “Date Received” will trigger the automatic display of an additional column.
For instance, if a user chooses to sort their inbox by size, the application will now surface a “Size” column in the message list. By making the data that dictates the sort order visible, Microsoft aims to streamline the user experience, reducing the necessity for manual adjustments or individual message inspection.
Added Functionality for Task Management
In addition to the visual changes for sorting, Microsoft is introducing support for sorting by “Flag Due Date.” This addition is designed to assist users who manage their workflows and deadlines through flagged email items. This feature is part of a broader push by Microsoft to encourage users to transition to the New Outlook for Windows, following a recent company blog post that outlined 15 reasons to adopt the newer version of the application.
Outlook Availability and Rollout
The update is slated for a broad release across both the New Outlook for Windows and Outlook on the web throughout June 2026. While the Microsoft 365 roadmap provides these expected timelines, the company notes that schedules can be subject to change. Users currently relying on the “Filter” menu to manage their message views will see these improvements reflected automatically once the feature is deployed to their specific tenant.
