Dear All, I wonder if anyone could help. At our company we utilise both Office 2002 and Office 2007 (these files automatically save as DOC '97-2003'), which run on Windows XP Pro PCs. We have a particular problem which has only just materialised... basically when a networked XLS or DOC file has been access and modified (on Excel 2007) we are unable to save the file back to the shared folder? I have tested other software application and I am able to make changes in the same location and also save without any issues. I have also created a new file with Excel 2002 and save that in the same location etc and I am able to change and save the file with no issues. So I have come to the conclusion that this issue is related to Office 2007. Can anyone help? Thanks in advance.
