The Demise of the OWA Light Client

OWA Light had an important role when bandwidth, browser compatibility, and limited client capabilities were real constraints.

Its retirement is another small but meaningful step in the modernization of the Exchange ecosystem.

For organizations still running Exchange Server, changes like this are also a reminder that modernization is not only about upgrading infrastructure. Legacy client dependencies, accessibility requirements, integrations, and user workflows all need to be part of the assessment.

Removing legacy technology is easy. Understanding who still depends on it is the real migration work.
