Hello, is it possible to deactivate all user (not the Designer or approval

The personalization utilities plug-in available for download here in Forum has a smart service to deactivate in bulk.

You can simply create a group with all users you want to deactivate (probably faster if you use a group membership rule) and use getdistinctusers(topeople()) over that group and pass that to the plugin

Thanks Eduardo it works ...
I'm used deactivate users (from your custom plugin) and reativate user.
The deactivate users disable all user and after the reactivate user reactive only the user that I want.. :D
