Microsoft has warned that Edge's IE Mode will only be supported through 2029, and modernisation of legacy web apps can take years.
Microsoft has warned administrators that Edge's IE Mode will only be guaranteed to support legacy web applications through 2029. The company also cautioned that modernising those applications can take years.
The warning gives organisations a deadline for migrating away from the compatibility feature, which allows older Internet Explorer-dependent sites to run inside Edge.
Why this matters: Organisations relying on IE Mode for legacy web apps have a limited window to plan and complete modernisation before guaranteed support ends.
What this means for you: If your organisation depends on IE Mode for legacy web apps, you may need to begin modernisation planning before the 2029 deadline.
