Opened Excel file stored on my hard drive's OneDrive folder and noticed it was not the latest version. Opened a backup of same file on my network drive, did my work on it, saved it. Then tried to copy over the latest network drive version of Excel file to OneDrive folder. It won't copy (replace) over the OneDrive file! Had to delete the OneDrive file, then copy over to it! OneDrive is not working correctly!!!
