I had this question after viewing
Accidentally deleted several users.
I have a problem, I have deleted the users out of Domino. Now I need to restore, I have restored their nsf file, but is there something I can do to restore the user back again or do I need to create a new user and somehow get them to access this .nsf file ?
If the users still have their valid ID files, they should be able to access their mail databases. Maybe you can re-create those users and set the security information in the newly created Person document to information contained in the existing ID files.
