Hi @david-cslu ,
Try this method:
Win+R and enter regedit, open registry editor go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Desktop\NameSpace.
Find registry with name "OneDrive - oldcompany" and "Oldcompany in list, then delete them.
Serious problems might occur if you modify the registry incorrectly. Before you modify it, please remember to back up the registry for restoration in case problems occur.
