Track Changes Error: "Operation cannot be completed. Try again later." Excel 2010 shared workbook

Question

I have one user who cannot make changes to a shred workbook.

This workbook is located on a server share and is accessed and ammended by 5 users.

Despite having the appropriate NTFS permissions added she gets the "Operation cannot be completed. Try again later."  message when opening the workbook and when attepting to ammend anything within the workbook.

I can setup other users to ammend the shared workbook.

All users are running Office 2010 and the file is an XLSX document.

Any suggestions would be great.
