Subject Field in Outlook

PureHeart

Hi to All,
i did some modification to the outlook synchronization codeunits because i wanted to put in the outlook field "File As" the value "Surname, First Name Middle Name". I was successful doing this just changing few lines of code but now in the Outlook Field "Subject" is being stored the same value of "File As", instead what I would like to have is "File As" := "Surname, First Name Middle Name" and "Subject" := "First Name Surname". I can't write directly in the "Subject" field like I do for the "File As" and I don't understand why outlook changes automatically the field "Subject" accordingly to "File As" if I change it via code.....
Please can someone Help me?
