I am integrating outlook and lotus notes .
if user wants to email the lotus notes document then one dialog box will open then user will select the name from the personal address book or public address book.
then mail(outlook) will be generated with doclink(.NDL file) to documents for internal user and for external user documets contents are mailed.
my problem is once user select name from address book how can i check whether the user is internal or external?
because based on user i have to select the function for sending document. those functions are working fine .
Please help me out .
it is urgent
