Cant get the mail adrres when sended mail with name not mail addres

[yusuf-sengun]

I have the following data in pst file

,Yusuf Sengun","/O=EXCHANGELABS/OU=EXCHANGE ADMINISTRATIVE GROUP (XXXXXXXXXXXX)/CN=RECIPIENTS/CN=XXXXXXXXXXXXXXXXXXXXXXXXXXX-YUSUF SENGU","EX","[email protected]","[email protected]","SMTP",,,,,,,,"Normal",,,"Normal"

There is no doubt in here I can get the mail address with getDisplpayTo function But when I send mail with a name not the full email address I get the following data

,Yusuf Sengun","/O=EXCHANGELABS/OU=EXCHANGE ADMINISTRATIVE GROUP (XXXXXXXXXXX)/CN=RECIPIENTS/CN=XXXXXXXXXXXXXXXXX-YUSUF SENGU","EX","ֺSample Name ,"[email protected]","SMTP",,,,,,,,"Normal",,,"Normal"

Here there is no way I can get the mail address getDisplayTo function return the Sample Name and other get function return something else I cannot take the mail address here
