Always On solution - Students registration

Hy,

I've tried to submit students of my classroom to the Always On solution. I've already ask a licence for myself and it's worked perfectly. I already succeed to add a colleague (wich had asked for an account previously) to my 3DSpace.

I did the same for students throught massive inscription with the file provided last friday. I only received the mail for registration informations. My students didn't receive any mail about the registration. Is it normal?

I need this solution for my course of tomorrow afternoon. I need to transfert some CAD models to my 3D Space. We're using 3DExperience at the school but only some students managed to install native apps on their computer due to technical requirements.

Thanks for your time and answer.
