The edit box contains the string with the usual text prefix '. If I

any hits. Why? More important, what's the best way to make the changes
please?

the prefix is readonly and cannot be deleted with replace method.
You can get rid of it clearing all formats. But the text doesn't change
to a valid email address.
Try it this way (for addresses in column A):

Sub Test()
Dim rngC As Range
Dim LRow As Long

With ActiveSheet
LRow = .Cells(.Rows.Count, 1).End(xlUp).Row
For Each rngC In .Range("A1:A" & LRow)
rngC.ClearFormats
.Hyperlinks.Add _
anchor:=rngC, _
Address:="mailto:" & rngC.Text, _
TextToDisplay:=rngC.Text
Next
End With
End Sub

Thanks Claus, and sorry for my delay in replying - been on holiday.

That works a treat!
