Unfortunately, Word doesn't provide a global setting, or even a 'Links' collection that one could use to programmatically change all the links. All that leaves you with is a macro to go through every field, shape and inlineshape in the document, looking for links to re-set. A macro you might use for that is:
Code:
Sub ToggleLinkUpdates()
Application.ScreenUpdating = False
Dim Rng As Range, Fld As Field, Shp As Shape, iShp As InlineShape, Rslt As Variant, bUpd As Boolean
Rslt = MsgBox("Set Link Updates to Auto (Y) or Manual (N)?", vbYesNoCancel, "Toggle Link Updates")
If Rslt = vbCancel Then Exit Sub: If Rslt = vbYes Then bUpd = True: If Rslt = vbNo Then bUpd = False
With ActiveDocument
For Each Rng In .StoryRanges
For Each Fld In Rng.Fields
If Fld.Type = wdFieldLink Then Fld.LinkFormat.AutoUpdate = bUpd
Next
For Each Shp In Rng.ShapeRange
If Not Shp.LinkFormat Is Nothing Then Shp.LinkFormat.AutoUpdate = bUpd
Next
For Each iShp In Rng.InlineShapes
If Not iShp.LinkFormat Is Nothing Then iShp.LinkFormat.AutoUpdate = bUpd
Next
Next
End With
Application.ScreenUpdating = True
End Sub
