I have a group named ICT and email address firstname.lastname@example.org and three people with rights to send on behalf of this group. They have setup their personal account on their PCs / Outlook and when they send they go to from and pick this group email address to send emails to the people. The problem is that the recipient does not see the on "behalf of" but the from field is only the group email address. How can I make this to work?
