I want to remove an article in IEEE, accepted but not published yet Now I am facing a very serious problem that I have to remove an article which is accepted by IEEE but will be published till the end of 2019. 

Due to some conflicts of interests(we finished this manuscript last year, this is my idea at the first place, and I finished the data analysis and processing part, all of the experiments, professor X wrote part of the document), he wants to hold the paper and wait for a top journal, but I'm in an urgent circumstance to graduate. So after half a year anxious waiting, I submitted this paper without noticing him. 

Until this paper was accepted to be published, I struggled for a very long time, so after I realized my mistake, I took action on this matter immediately. Firstly I negotiated with the professor X, He was tough on this thing and disagree with my behavior. After mature consideration, I want to completely remove the article and contact with IEEE Journals Coordinator immediately.
This negotiation has lasted several months，and now I hold the firm attitude that I have to remove this article no matter what kind of excuse it will be given. It cannot be seen on any version no matter online or offline. Still waiting for IEEE's reply, and could you all please give me some advice under this circumstance? Many thanks!!
So, the issue here is that you submitted a paper without the consent of one of your co-authors? Write to the editor of the journal explaining that, and ask for the paper to be retracted. Even if you’ve agreed to give them your copyright, your coauthor hasn’t, so they wouldn’t be allowed to legally publish it anyway.
