We have a problem with some users sending emails to an external email address and CC'ing an internal group (AddDev). The external user receives the email with the CC containing "AppDev" I know an internet address will replace the "AppDev" if the group document contains an internet address (firstname.lastname@example.org). In this case "AppDev" does not contain an internet address.
I know, if the user remembers, can click on "More - Expand Public Groups" will replace "AppDev" in the CC with the user names within that group.
Is there a way to eliminate the user having to click "More - Expand Public Groups" and have the server automatically do it if the is being externally sent?
