Microsoft to Retire OWA Light, Exchange's Lightweight Webmail Client
Microsoft has announced that OWA Light, the simplified version of its Exchange Server webmail, will be discontinued. The shutdown is scheduled for an upcoming update in August 2026, marking the end of nearly two decades of service for the client. OWA Light was introduced with Exchange Server 2007. It served as a crucial fallback option for users with limited web access or older browsers, including early versions of Firefox, Safari, and Opera. The client also provided essential functionality for users relying on screen readers. Its discontinuation signifies a shift in Microsoft's strategy for its email and collaboration services.
The deprecation of OWA Light by Microsoft reflects a broader industry trend towards consolidating services and focusing on more robust, modern web technologies. As internet access and browser capabilities have advanced significantly since OWA Light's inception, the need for a lightweight alternative has diminished. This move allows Microsoft to streamline its support efforts and invest resources into enhancing the primary Outlook Web App experience. Organizations that still rely on OWA Light will need to plan for migration to ensure continuity of service, potentially evaluating their current Exchange infrastructure and user accessibility needs in light of this change.
