There are two issues that could be involved here - the linked range changing and the size of the linked worksheet changing in Word.
For the first issue, give your Excel range a name (e.g. WordLink), then edit the LINK field's address to point to that name. For example:
{LINK Excel.Sheet.8 "C:\Users\UserName\Documents\Workbook.xls" "Sheet1!R1C1:R10C6"}
becomes:
{LINK Excel.Sheet.8 "C:\Users\UserName\Documents\Workbook.xls" "WordLink"}
Now, the link should only retrieve what;s in the named range. This approach also has the advantage that, should the range spanned by the name change in Excel, the link in Word will update to reflect the change.
The second aspect requires a registry edit on all the affected PCs, since the resizing of linked Excel Objects is by design:
- Open the Registry Editor, then navigate to:
HKEY_CURRENT_USER\Software\Microsoft\Office##.0\Excel\Options
where ## is your Office version number. - Add a new DWORD value: QFE_Boston
- Set the new DWORD value to 1
Try the first approach and see if that solves the problem before going for the second one.
