I ran across this article, also on ZDNet, which digs a little deeper into why getting rid of Internet Explorer may have other implications.

Saying goodbye to Internet Explorer might be more complicated than you realise [sic]

Could this be the beginnings of a workaround for legacy applications like Eudora? Does this even matter? I’m keeping my eye on it anyway because of Eudora’s dependency upon the “Microsoft Viewer”, when it’s selected to display messages.

Someone pointed me at an article appearing on ZD-Net’s Extreme Tech site – “Microsoft Will Put Internet Explorer Out of Its Misery Next Year“ – which states that IE will be sunset for good June 15, 2022.

The article is focused on the aging browser itself but then these sentence appear.

It’s clear Internet Explorer doesn’t have a place in Microsoft’s online efforts with its clunky old rendering engine. After the shutdown, Internet Explorer will no longer be available on any consumer version of Windows 10.

Isn’t that “clunky old rendering engine” what Eudora’s using when Microsoft’s viewer is selected for viewing messages? As it happens, the answer is yes.

So, what will happen in 2022? Only Microsoft knows for sure. I suppose it comes down to whether or not Microsoft will actively remove the files that make up the rendering engine.

I raised the topic this morning on the Eudora for Windows list and some discussion is beginning to take shape. As someone there said, it’s not time to panic.
