A few years ago, I lost access to my school email and had to create a new personal email for windows. My files sync fine with the new email, but once a day, I get a prompt asking me to sign into sharepoint and when I click the button to sign in, the only option I have is for the school account which I don't have access to. I deleted everything that started with Microsoft Office from credential manager that didn't have my personal email in the username field, ran the command C:\Program Files\Microsoft OneDrive\onedrive.exe /reset to reset onedrive, and uninstalled/reinstalled onedrive to no avail.

Does anyone know what I missed here or why my school account is still connected?

EDIT: I saw a SSO_POP_User credential that I missed in credential manager. Maybe that will fix it. I just unlinked and link my account and wasn't prompted to sign in; however, when the select an account prompt comes up, the school email appears in the list of options.
