Highlight emails based on internal or external addresses. Green for internal and red for external.
When sending emails its important to verify if the email is going to the correct recipient. While it's nice to view the names as FN LN in the TO: fields I have thousands of contacts and when sending sensitive information I end up viewing the properties of each to verify the email is going to the correct john smith and also verifying they are all internal recipients. It would be nice to have all internal recipients be highlighted in green and all external highlighted in red. perhaps other lists/categories can also be created to easily view recipients of different mail classifications/sensitivities. Highlighting the addresses would help quickly identify how safe clicking the send button is.
I totally agree with this idea.
Outlook for Windows has some of solution for such a incident. for example VBA add-on. I think that Outlook for Mac need something like that, too.
This idea is simple and smart rather than VBA support.
