I have to answer to my own question…
I’m in progress, but not enough ;
– in session user, pwd is not asked for cipher or uncipher ;
– in session administrator, the pwd is asked 🙂
– if I accept to type pwd, Outlook keeps authorization for ever :
or I want authorization to be kept only for the Outlook session duration.
– how to have the pwd to be typed in session user as well ?
Thanks for help.
