Mouse slip?

If you suspect this is due to a client related problem, you could enable
telemetry logging to find out who/what is causeing the emails to go missing.

If the purpose is to (mostly) copy emails into the folder and rarely delete,
you could restrict delete access to a specific account via ACL.
