Enhancements in Microsoft’s New Outlook for Windows: Offline Calendar Support on the Way
Microsoft is ushering in a new era for its Outlook application with the introduction of the New Outlook for Windows. While this version is being integrated as default for new Microsoft 365 installations, it has received mixed feedback, primarily due to the absence of several sought-after features.
Despite the app entering its testing phase nearly three years ago, many users continue to express dissatisfaction with its capabilities. However, there is a silver lining: Microsoft is actively responding to user concerns and making meaningful improvements.
One of the recent enhancements includes the ability to run the Classic Outlook alongside the New Outlook, eliminating the need for users to switch between the two versions constantly. This flexibility aims to retain user engagement while the new features are rolled out. In addition, Microsoft has been progressively adding crucial functionalities, such as Personal Storage Table (PST) support and enhanced offline capabilities.
Last year, the tech giant initiated the development of an offline mode for New Outlook, allowing users to access the application without an active internet connection. This update also introduced offline email synchronization and the capability to open attachments when offline.
The latest advancement announced is the addition of offline support for the Calendar feature. This upgrade is expected to enhance user convenience significantly, as it mirrors similar functionality migrated to Microsoft Teams.

What’s New in Offline Calendar Support?
The details regarding offline Calendar support have been confirmed through a recent entry on the Microsoft 365 roadmap. It states the following:
Outlook: Offline Support for Calendar – Create, Edit and Delete Event support
We are adding more offline functionality in the new Outlook for Windows. You will now be able to create, edit, and delete events in your calendar when not connected to the internet.
According to the roadmap, the rollout for offline Calendar support is expected to begin in June 2025. While this timeline gives anticipation for users awaiting enhancements, it’s essential to note that feature deployments are sometimes subject to delays. For further details, users can refer to the entry ID 490059 on the Microsoft 365 roadmap website.
With each of these developments, Microsoft is taking significant steps to enhance the user experience for Outlook, ensuring it meets modern demands and user expectations.
