Microsoft has given organisations a clear deadline for Edge's IE Mode, the compatibility feature that lets users run legacy web applications built for Internet Explorer. According to The Register, the company says support is guaranteed only through 2029, after which the mode will be retired.
The warning is aimed at administrators who may be treating IE Mode as a long-term bridge. Microsoft notes that modernising legacy apps can take years, so waiting until the deadline is risky. The Register reports that Redmond is urging admins to start planning now, even though the exact end-of-life date after 2029 has not been specified.
The message is straightforward: the clock is ticking. Organisations that depend on IE Mode should treat the next few years as a migration window, not a permanent solution.
