Hi. Welcome to the forum. I'll try to give you a copy/paste approach for now, since I am not sure I understand the report connection at this time. So, you could try to put an unbound textbox on the header of your form. Then, you could try to populate it with the email address and just copy and paste the result whenever you need it. To do so, you could try using the following code in the Click event of your button.
Me.TextboxName = Me.TextboxName & "," & Me.EmailAddressField
Hope it helps...
