Can anyone help me to solve this problem

If a user pressed the send button for a new mailmessage, I need to know all
the recipients they want to send the message to.
But if a user selects a recipient from a personal addressbook, and the given
name is like last, first, then I get as a result of the token
addressbookresolve Token failed execution.
strTo="Puk, Pietje"
strParam="AddressbookResolve(""" + strTo + """;1;1)"

Is there any way to solve this?

Thanx in advance.
