I have a lotus Note 6.5. My domain network Active Directory is integrated with Domino. When I create new user account using active directory, It is automatically create a domino account for that user in domino. The problem now for the mail file. The system choose the mail file to be (The 1st letter from the first name+the family name. e.g. John William:jwilliam.nsf). But if I have two users (John William and Jack William the mail files will be the same i.e. jwilliam.nsf) and this will make a conflict. My question is it possible to make the mail file the same as the user id (i.e. S970851 if every user has an academic ID and his user name is S+his id) to make it unique. If not, plz tell me how can I make unique.
