I would like to have that too. And that the database-Option can be used with Import .csv
I need this because we had to set Admin-rights for a third-Party-product on one database.

The latest version already has the ability to import users into specific databases. We won’t ever allow the company admin to select from the current list of databases. We would have to design something where you can specify which databases they can see and only choose from that list.

Yes, I see Your problem.

But I need to have this feature so that our Helpdesk can do the “normal” tasks (create user) on its own.

Database Scopes is what we need…

The database option for import CSV has been added and if you manually create users and leave the default “Let Exchange Decide” then it will automatically distribute across the databases as you mentioned in the Microsoft link.
