Lotus Symphony was first installed alongwith Lotus Notes 8.5. Subsequently, Lotus Symphony was uninstalled.
Now, spreadsheets (especially, .XLS files) always open from mail attachments, in the Lotus Notes embedded browser instead of Microsoft Excel or OpenOffice Calc.
How do I prevent Lotus Notes from opening spreadsheets, and have either Microsoft Excel or Lotus Notes open such attachments from emails.
Many thanks in advance.
