Microsoft to Introduce ICS Calendar Support in New WebView-based Outlook, Enhancing Cross-Platform Compatibility

In March, Microsoft introduced a new version of Outlook based on WebView, which has gradually added support for third-party email services such as Gmail, Yahoo Mail, and iCloud Mail. The updated Outlook boasts an improved interface and integration with various Microsoft 365 services. However, user experience may vary, with some, like those at Blue Dot, opting to continue using the Win32 version of Outlook.

One issue the new Outlook currently faces is calendar migration. To address this, Microsoft plans to introduce support for traditional ICS calendar files in future updates. ICS files are a long-standing calendar file format that allows users to import and export calendars across different platforms, facilitating migration between them.

According to the Microsoft 365 roadmap, ICS file support will be available in the new Outlook around October. Microsoft promises comprehensive ICS calendar file support, enabling users to both import calendars from other platforms to Outlook and export ICS files from Outlook for migration to other platforms.
