Macro delay while saving to OneDrive - Excel 2013, Win 8.1

[Yamezz]

I have macro that creates an invoice from a job card entry, prints the invoice, clears the job card for the next job and saves the file. This macro was working fine with XP and Excel 2007, but a recent 'upgrade' to Win 8.1 and Excel 2013 has resulted in a lengthy delay to the macro, while it waits for the saved file to be uploaded to OneDrive. What could be causing this and what's the solution? I have tested with Excel 2010 running on Win 7 with OneDrive and don't have this problem. The file saves to the hard drive then backs up in the background, without causing a delay to Excel.

Thanks.
