OneDrive Issues

I have a user who moved files over to his one drive, but before checking to make sure that all files were copied over, he had deleted the files. After some time, he went to open a file from Onedrive, and it is not there. All of the sub folders are there, but none of the actual files were moved over. Other than having the hard drive taken to a professional to see if the files can be recovered, any suggestions?  I have looked at all recyclable bins, previous versions etc. 
Thanks
