A Microsoft file hosting and synchronization service.
Dear Drew T_091,
Thank you for reaching out to us. I understand that you've encountered some significant issues with OneDrive on your MacBook Pro, and below are some suggestions for your scenario.
I understand your frustration, I know how hard it is to work when things don’t go as expected. However, we can work together to narrow down and resolve the situation.
Please check these steps for account confusion:
1.Open OneDrive and go to Preferences > Account. Ensure that you are signed in with the correct account and not the old education account.
2.If the old education account is still linked, you may need to remove it by going to System Preferences > Internet Accounts and deleting the old account from there.
3.After removing the old account, restart OneDrive and sign in with the correct account.
It seems this issue occur after update MacOS, if it possible, you may completely uninstall OneDrive and setup/configure again and verify the result with us. I'm sorry and I apologize for that.
Thank you for your patience and understanding.
Best regards,
