At Build 2019, Microsoft announced it would release Internet Explorer on its Chromium Edge preview browser through a feature called IE Mode. However, after the event the company start peddling backwards.
Specifically, instead of introducing it for all users as announced, Microsoft limited IE Mode to IT admins only.
Microsoft seems to have had a change of heart and the IE-Mode is now back. However, it seems to be more hidden in the mix than it previously was on Chromium Edge. Also, users are likely to see a warning when they update the Edge Developer channel next week.
Specifically, they will be warned that using unsupported command-line flags could cause a security risk.
With its new position, you have to head to the command line and choose “Open Sites in Internet Explorer mode”. There is no longer any access to the feature from the standard Edge menu.
It is worth remembering this is for the Dev channel, which is the development branch that sends out weekly updates.
As we have previously reported, Chromium Edge is so far only available on Canary and Dev channels. Canary builds are daily and unstable, whereas Dev releases are weekly and a little better. However, Microsoft previously announced a beta channel, which would be more stable.
Yesterday, a leak suggested Microsoft is planning two new channels. The aforementioned Beta and a previously unknown Stable channel. This is the first time we've seen a beta version for Chromium Edge in the wild and indicates that this phase of testing is coming soon.
Both installers come directly from Microsoft's servers but aren't listed on its website. They were spotted by Twitter's WalkingCat. The stable Edge version returns the error “There was a problem installing due to a server issue. Please try again later”.
