My team has been communicating with an outside party that uses Office365 encryption. When they send an email to my team, the message I see looks like this:
To: teammemberA@mycompany.com, teammemberB@mycompany.com, me@mycompany.com
Body: You've received a protected email from outside party ... sign in using the following email address: me@mycompany.com
However, Team Member A sees the body as telling them to sign in using "teammemberA@mycompany.com", not "me@mycompany.com".
I was just wondering how Office365 manages this? Is there a feature of HTML email, or an Exchange server trick that lets you specify that a recipient should see their own email address? My company uses Outlook as the email client, and Exchange as our email server, so is this an Outlook- or Exchange-specific feature I don't know about?
