We would like to enforce periodic password changes with Unity 4.2(1). If I turn on password expiration does it count out x number of days from the day I turned it on? If so, is there a way I can have evryone forced to change their vm password and set the expir. to 6 months? Also, what does the user hear when their password expires? We are using Unity with Exch 2003 if that matters. Thanks.
