The sendgmail function, which I write by myself and works well on version MATLAB 2015b, is not working on version after 9.0(MATLAB 2016a and 2016b)

The m file shows as follows.

function lzhanu(recipient, subject, content, attachment)
% MATLABMAIL Send an email from a predefined account.
% See also sendmail.
sender = '*';%It is sender address.
psswd = '*';%It is sender password.
setpref('Internet','SMTP_Server','smtp.gmail.com');%It is the smtp serve of sender's mail.
setpref('Internet','E_mail',sender);
setpref('Internet','SMTP_Username',sender);
setpref('Internet','SMTP_Password',psswd);
props = java.lang.System.getProperties;
props.setProperty('mail.smtp.auth','true');
props.setProperty('mail.smtp.socketFactory.class', ...
  'javax.net.ssl.SSLSocketFactory');
props.setProperty('mail.smtp.socketFactory.port','465');
switch nargin
  case 3
      sendmail(recipient, subject, content);
  case 4
      sendmail(recipient, subject, content, attachment);
end
disp(['The email to ' recipient 'is successful!'])
end

The function works well on Matlab 2015b, but when I use Matlab 2016a, I went wrong and command window shows that

Could not connect to SMTP host: smtp.office365.com, port: 25;
Operation timed out
Error in sendgmail (line 23)
      sendmail(recipient, subject, content);

Can anyone explain the reason and help me tackle this problem? Thank you!

Hi Zihao,

This issue could be related to the following MATLAB Answers post: https://www.mathworks.com/matlabcentral/answers/229092-sendmail-authentication-error-with-gmail

Also, check that your MATLAB web settings are the same between both your R2015b and R2016a installations. You can check these settings by going to Preferences > MATLAB > Web.
