Easily done but you might prefer to take the user out of the process and
save the workbook as your new name when you close it?

For the pop-up upon opening...................

Private Sub Workbook_Open()
MsgBox "This file must be re-saved as XXXX"
End Sub

To saveas XXXX.xls when closing...................

Private Sub Workbook_BeforeClose(Cancel As Boolean)
'Note that any existing "XXXX" workbook is overwritten
If ActiveWorkbook.Name = "XXXX.xls" Then Exit Sub
Application.DisplayAlerts = False
ActiveWorkbook.SaveCopyAs Filename:="XXXX.xls"
ActiveWorkbook.Save 'saves original workbook also
Application.DisplayAlerts = True
End Sub

Both of these go into Thisworkbook module.

Right-click on the Excel Icon left of "file" on the worksheet menu bar and
select "View Code"

Paste whichever event you want into that module.

Is there a way to create a pop up message in Excel upon opening a workbook?
I want to create something along the lines of "resave this file as xxxx".
