Hi @John Peter
According to your description, it seems that your OneDrive is installed successfully, but you cannot sign in the account, the OneDrive setup failed.
The path on the image includes "Shared Folder". Please make sure this folder is deleted on OneDrive online or SharePoint.
If yes, I suggest you uninstall OneDrive again, locate the OneDrive in your Applications folder and drag it to the trash bin.
- Open Finder, click "Go" in the menu, and choose "Go to Folder." Enter "~/Library/Containers" and click "Go." Find the "com.microsoft.onedrive-mac" folder and delete it.
- Reinstall OneDrive from the App Store or "OneDrive release notes" for a check.
Besides, please try the steps in "Fix OneDrive sync problems on Mac", such as reset OneDrive.
