Office 365 User only has Read permission on his own OneDrive root folder

[JohnnyCYip]

We have over 400 Office users. One of them is having a weird issue which his OneDrive is showing a different user name (an user who had been gone few years back) and he can't add or remove any files and folders (can't sync neither). And he can't even add files or folder on the online OneDrive portal.

What's the best way to get this resolved?  How can I (as a global admin) delete the old OneDrive folder on his account and create a new one? Thanks in advance!

Try this.
1) Give your admin access to the user OneDrive using the old admin user profile center and remove access to the user. (https://yourtenant-admin.sharepoint.com/_layouts/15/TenantProfileAdmin/ManageUserProfileServiceAppli...)
2) Using an admin account connect to the user onedrive https://yourtenant-my.sharepoint.com/personal/useraccountondrive/_layouts/15/people.aspx?MembershipG...
3) Select the user and Action|Delete user from site collection
4) Go back to step #1 and add the appropriate user and remove the admin rights.

Let me know.
