Microsoft has told IT administrators that IE Mode in Microsoft Edge, which is the final method of running the Internet Explorer engine on modern Windows, will be discontinued by the end of 2029, as stated in a message on the Microsoft 365 admin center.
Although Internet Explorer 11 was retired many years ago, its engine is still in use via IE Mode. The company is advising organizations to start migrating the legacy applications that still need Internet Explorer at this time, since some modernization projects can take several years.
Microsoft has stated that it will give a new end-of-support notice at least one year before the actual date.
Even though IE Mode will likely continue working with few issues after 2029, Microsoft asks organizations to prepare now:
- Evaluate the IT infrastructure to identify those elements which are still necessary to run in IE Mode from the point of view of the business and its missions.
- Refresh, reupload, replace or reconstruct those applications and websites using modern web technologies.
- The App Assure service offered by Microsoft can assist eligible customers in checking and improving the compatibility of their custom applications with the newer Windows platforms.
