SharePoint 2013 One Drive Issues

OneDrive not syncing with SharePoint and need a few ideas on what could be wrong?

1. Make sure SharePoint MySite and profile features are enabled
1. A corrupt MySite can prevent some account from syncing, we managed to fix an account by deleting it and recreating it. 
1. If you cant recreate the account then (after backing up the server / data)
1. Copy another users account (an empty one)
2. Rename it
3. Give the users permissions
4. Set the mysite address in their user profile page.
2. There are some issues with running the OneDrive client from a Citrix desktop
3. Check the storage metrics page the user has enough Storage
4. Try to resync
5. Try the Microsoft diagnostic tools
