    Recently I have been swapping some email with Microsoft domains and then I analyzing the emails that landing in outlook domain in the first line i have:
    Code:
    
    This message was identified as junk. It's not junk
    
    This message has a digital signature, but it wasn't verified because the S/MIME control isn't currently supported for your browser or platform.

    All others "big boys" such us aol, gugl, proton, fastmail, etc. They all get the mails directly in inbox.
    It is so sensitive even removing user-agent from the source of the mail (header_checks) automatically exchange classifies as a junk.
    I am guessing additional script on the horizon.

    I was wrong (not first and certainly not last time) it is Microsoft does support for end users mail encryption however I have found some git project that support/create a simple way S/MIME certificate which does encrypt mails, however Microsoft still pops up the unsupported note.
    Link too the github project:
    https://github.com/gunnarhaslinger/SMIME-OpenSSL-CA
    the other way is waiting for openPGP to comes up with additional S/MIME key soon.

    So I am guessing there will be two keys merged and supported by Thunderbird.
