Getting to view the CPI documentation for Mitel's MiVoice MXONE always has a challenge. My personal favourite is to just use a Python or Go web server. But here is a solution which works just as well, albeit less exotic:
1. Enable the "Internet Explorer mode button" in Edge by opening Edge's menu > Settings, and search "Internet explorer"
2.Following the link, and change the setting to "Allow":
3. Now right-click on Library Browser.htm and open with Edge.
4. The page will not open in the correct mode immediately. But from Edge's menu, select "Reload in Internet Explorer mode"
And now it should be working smooth. Follow the small pop-up's instructions to save the changes.
