Hi @Clark ,
Welcome to Q&A forum!
According to your desription, I want confirm the following inforamtion with you.
- Are you using the Onedrive for Business? How and where did you get the OneDrive account?
- Are there any error messages when trying to log in to OneDrive online?
If you cannot log in to OneDrive online, it is not ruled out that it is caused by your account.
- Please make sure you are trying log in the correnct account.
- I also suggest that you try to connect other networks to check this issue. If condition permits, you could also try to log in OneDrive on the another PC to check again.
Besides, please check if Rena Yu's suggestions in this thread is helpful to you.
Any updates, please let me know.
