after setting the Mailto function to open in O365 Web portal getting blocked by protected mode RRS feed

  • Question

  • Our end goal is that when someone selects an email link inside of Internet Explorer it goes to either the O365 Outlook login page or presents a composed email from https://outlook.office.com/owa/. We have been able to accomplish these settings using the following command line:

    ftype mailto="C:\Program Files\Internet Explorer\iexplore.exe" "https://outlook.office.com/owa/?viewmodel=IMailComposeViewModelFactory&wid=62&ispopout=1&path="

    This works 100% of the time when Protection mode is disabled for the Internet zone

    When protection mode is enabled we get the prompt

    "A website wants to open web content using this program on your computer"

    Name: Internet Explorer 11

    Publisher: Microsoft Corporation

    when I select "Allow" nothing happens and I'm not seeing any corresponding event logs to why this is happening

    Looking for how to get past this while still having protection mode enabled
