You can set the DisplayAlerts property of the Excel application object to false to stop these dialogs from appearing.

The following is a simplified version of your code:

e = actxserver ('Excel.Application'); % # open Activex server
filename = fullfile(pwd,'example2.xlsx'); % # full path required
ewb = e.Workbooks.Open(filename); % # open the file
esh = ewb.ActiveSheet;

sheet1 = e.Worksheets.get('Item', 'Sheet1');
range1 = get(sheet1,'Range', 'A1');
range1.Value = 3;

set(e, 'DisplayAlerts', 0); % # Stop dialog!

xlWorkbookDefault = 51; % # it's the Excel constant, not sure how to pass it other way
ewb.SaveAs(fullfile(pwd,'example2'), xlWorkbookDefault)
ewb.Close(false)
e.Quit
e.delete
