And your solutions works without IE mode, but unfortunately they do not solve my problem.
If i have a hypelink: <a href="y:\FolderName\10000.docx" target="_blank" >link to file</a> and click on it from Internet Explorer, the file will be opened with Microsoft Word from that location. The user can then edit the document and save the changes without specifying the filename or dowloadning the file.
If i do the same with Chrome or Edge (Beta), nothing happens when clicking the link. And looking at the console is see this message.
The same happens if i change the path to servername...
I can solve it using an extension called IE-tab, but i thought that i could do it smarter without an extension in Edge due to its IE-Mode and the site liste, by forcing edge to open local file links in IE mode.
If i paste the url in the browser like your suggestions, the file will be downoladed locally which i dont want, because it is then no longer a shared file in a shared folder. I use the intranetsite for managing a lot of documents, where the users can edit these.
