We have several companies that we have established forced TLS with via our Exchange 2010 server. How do my users know if the email address is one that will be going via TLS?
For example, let's say we have abc123.com entered as someone we DO have forced TLS with. xyz.com is NOT someone we have forced TLS setup with. My user is going to send an email to bob@abc123.com and can't remember if emails to 123abc.com or xyz.com will go via TLS.
My thinking is that Outlook could show the email address in a color or place and icon in front of email addresses that will be sent via TLS.
- bob@abc123.com <-- Green (secure)
- sue@123abc.com <--- Red (not secure)
