Send a custom email using the sendmsg.bat or .sh command with a clickable unc path in it.
For windows it would look like this:
sendmsg.bat -m EMAIL -r email.user@something.com -s "subject" -t "Here you can put anything you like and here is how to do the unc path coding: \"\\snap\share1\dgrimm\space%%20test\again%%20space\ \" And that is it"
For Linux Agent it looks like this:
./sendmsg.sh -m EMAIL -r email.user@something.com -s "subject" -t "Here you can put anything you like and here is how to do the unc path coding: \"\\\snap\share1\dgrimm\space test\again space\\" And that is it"
