Microsoft plans to retire OWA Light client in Exchange Server
Key points
- OWA Light will be disabled by August 2026.
- Introduced 20 years ago for older browsers and limited environments.
- Encourages users to transition to the full Outlook on the web experience.
Announcement of OWA Light Retirement
Microsoft announced it will disable the Outlook Web Access (OWA) Light client in a future update of Exchange Server. The preview of this change comes with the rationale to reduce legacy infrastructure and streamline the development of ongoing engineering tasks.
The retirement is part of a broader shift towards fully utilizing modern web email capabilities.
Background on OWA Light
OWA Light was introduced approximately two decades ago as a simplified web email client for users relying on older web browsers. It provided basic functionalities suitable for low-bandwidth environments and systems lacking modern browser capabilities.
Significantly limited compared to the full version, OWA Light lacked features like calendar viewing options, access to shared resources, and task management functionalities.
Reasons for Retirement
The web landscape has evolved substantially since OWA Light's launch. Modern browsers and improved network conditions have reduced the need for a simplified version of the email client.
A spokesperson from Microsoft indicated that focusing on the full Outlook web experience would be more beneficial moving forward.
Transitioning Out of OWA Light
Microsoft has set a timeline to disable and remove OWA Light, expected to occur by August 2026. Users will be redirected to the standard Outlook on the web version after this removal.
For immediate transition, administrators can disable OWA Light via command-line instructions provided in Microsoft’s documentation.
