Microsoft to End Internet Explorer Mode Support in Edge by 2029

Microsoft Confirms End-of-Support for Internet Explorer Mode in Edge

In a significant update for IT administrators, Microsoft announced that the Internet Explorer mode within its Edge browser will continue to receive support until at least the end of 2029. This directive is crucial for organizations still utilizing applications that rely on Internet Explorer's capabilities.

A Call to Action for IT Administrators

According to a notice published in the Microsoft 365 admin center, this upcoming change emphasizes the need for organizations that depend on IE-specific applications to commence migration planning immediately. As organizations navigate this transition, utilizing Internet Explorer mode allows Edge to load pages with the older Trident engine, which powered Internet Explorer 11.

Ongoing Commitment and Planning

Microsoft has assured that it will provide a one-year notice ahead of the final end-of-support date for IE mode. This advance warning is designed to give administrators ample time to rebuild or replace legacy software, acknowledging that such transitions can often take years to implement effectively. The company initially indicated plans to retire this mode back in 2021, underscoring its commitment to guiding users through the change.

Compatibility and Transition Solutions

For organizations that do not rely on any Internet Explorer functionalities, no immediate actions are necessary. However, those still dependent on IE mode should review their systems to identify which applications are affected. Microsoft recommends updating or redesigning these outdated solutions.

The Declining Role of Internet Explorer

The announcement about IE mode’s eventual retirement follows the official discontinuation of Internet Explorer 11 in June 2022, marking a major transition after 26 years since the browser’s inception. Post-retirement, Microsoft began redirecting users attempting to access IE towards Edge, reflecting a widespread migration already in progress, as Internet Explorer had dwindled to holding less than 1% of the browser market share by that time, according to StatCounter.

In conclusion, while Edge continues to support legacy applications through IE mode until the end of 2029, IT administrators are strongly encouraged to take proactive measures in ensuring a smooth transition away from legacy systems reliant on Internet Explorer.

Further Developments

As organizations gear up for these changes, keeping abreast of Microsoft’s updates will be key to maintaining operational efficiency in their IT environments.
