One more point,

I already created a newsletter campaignBut for that campaign I am not able to add Email Marketing Record as in Use mailbox dropdown i have no item and it is mandatory for creating email marketing.

Note I already configured outbound email setting from admin section(still it is not working but record is saved in database)

I have attached snapshot of my campaign record
