I'm not sure what is going on here, but see if you can make sense of this...
1. On the Mailings tab of the ribbon in Word 2007 you have
- Start Mail Merge
- Select Recipients
- Edit Recipients
2. Normally, when you create a new Mail Merge Main Document, you can start
by clicking either the first or the second of those. Only when you have
successfully selected a data source in "Select Recipients" does the Edit
Recipient List option become available. The option would be available if you
re-opened a mail merge main document wihth a data source attached and Word
successfully opened the data source.
If it's greyed out, that still suggests to me that she has not selected the
data source /successfully/ - i.e. she may actually selected it, but Word has
failed to connect to it and not displayed an error. I would consider
suggesting that she starts with a brand new document and tries again.
3. If it isn't actually greyed out, then when she clicks on it, she should
see the Mail Merge Recipients dialog box. The Edit button in there starts
greyed. Is that what she is seeing? To edit the data source data in there,
you have to select the data source "file" in the box above the Edit and
Refresh buttons. Then, if the data source can be edited, the Edit button
should ungrey.
4. However, what happens when you click on the Edit button in there depends
on the data source and how Word has connected to it. If the data source is a
Word document, you'll probably see the old "table" interface wher the fields
are listed in a single column with a a text box to the right. If it's an
Excel document and the connection is OLE DB (the defaul) you see an editing
pane that looks much more like a spreadsheet. If it's an Excel document and
the connection uses the old DDE method, the Edit button will probably be
available, but when you click it, nothing appears to happen (becuase in this
case, you're supposed to know that you go and edit the data directly in
Excel.
So what type of data source is she using? Does any of the above ring any
bells?
