Hi Jack Randall_233,
Thank you for reaching Microsoft Community. We appreciate for sharing your concern to us.
We get your desire to switch from your personal to business account so you can move your files. Nevertheless, your issue is somewhat tied to your job, and it appears that the account you are seeking to set up is managed by your company, which is outside the scope of our support boundaries in the community. We advise contacting your IT administrator for more setup assistance.
Wishing you all the best!
Kind regards,
Lavenia
