This blog describes how to set the target address attribut via a vb script in an Exchange 2003 organization.

First of all an Input file is needed to read the userlist. Targetaddress.csv is the file name used in the script below. The following two entries are the only attributes which are used.

LegacyExchangeDN,mail.. From the mail attribut value everything is stripped of after the @ and replaced with ex2010.de then this string is put into targetaddress with the SMTP:name@ex2010.de.

A log file is also created in the directory where the script is called. The filename of the log file is logging_set_targetaddress.txt

First the script reads the Input file targetaddress.csv. Then it tries to find the user with the E-Mail address of the value "mail".

In case the result is not equal 1 the script will do nothing and will write an error in the log file.

Please note that this script is just an example script and needs to be adapted
