I would like to know how to make contact with Box support

Hi there, 

Welcome to the Box Community! 

Upon checking, I see that you are under a free account and the only way to contact Box Support is through this forum. While we're always happy to assist any Box user who's having trouble logging in, for all other issues we only offer technical support to customers on one of our paid plans.

If you have a paid account under a different email address, please log in to that account when interacting with support to get access to the full range of available support options. 

Thanks!

how do I change the main email address on my free account?
