Outlook Web UXtras is a Chrome extension developed by warren.f.fernandes that aims to improve the user experience of the Outlook Web Client. This free extension focuses on two key features to enhance productivity and convenience for users.

Firstly, it allows users to turn off the "Request Response" option when creating a calendar item. This feature eliminates the need for users to manually select this option every time, saving time and streamlining the process of scheduling events.

Secondly, Outlook Web UXtras automatically opens the calendar sidebar in the mail inbox view. This eliminates the need to navigate to the calendar separately, providing quick and easy access to the calendar while checking emails.
