outside vs out of the box

Question

As a non native english speaker i wonder which one is the correct form to use ?

to think outside the box ? to think out of the box ?

is there any difference in meaning ?

Answer 1

Both can mean the same thing, although "verb- outside the box" is the correct form these days because of the excessive use of the "verb- out of the box" phrase in technology (software/hardware etc.) Latter more likely to mean that the subject succeeds to do the verb immediately after installation/unboxing.
