Encryption enabled by default for all O365 and MSN(Hotmail/Outlook/Live) Sites
It would be very compelling if at "least" on all Microsoft properties 2 way encryption would not only possible but enabled by default and seamless to the user.
For those where it would not be possible at least allow for the outbound to be sent encrypted if the Microsoft Customer so chose.
This would at least be a step in the right direction regarding Encrypted emails.
Which encryption are you requesting here? Is this about encryption at the server level (TLS), or S/MIME, or Office Message Encryption, or…? Microsoft mail services all use opportunistic TLS by default.
