did the icon come in the email as an attachment?
or was it in the body of the email?
- if as an attachment - then re-attach to new email and send to: recipients. go to new email> and in the "to" field insert the email addresses / contacts
- if in the body of the email then forward the email to: recipients. when you have the email that you received open, select "forward" and in the "to" field insert the email addresses / contacts
gave two different examples since im not sure if by "icon" - you actually mean a file that you saved to your computer then clicked on (clicked the icon for it) or an actual icon in the body of the email. by body of the email i mean the area of the email that shows the actual information / message.
another thing to note is that if you plan to send this file / forward this email to people and if its specific to a certain application, (ie; turbotax, outlook, ical, etc.,etc..) then the recipients must also have the necessary software installed on their computer to use it.
