Sending Emails with MATLAB

Hello,

I am currently running a script in matlab that sends an email out when it is through with a .pdf attachment. This was working flawlessly two days ago and now I can't seem to get it to work.

I am recieving the following error message:

Error using sendmail (line 175)
530 5.7.57 Client not authenticated to send mail. [BLAP220CA0019.NAMP220.PROD.OUTLOOK.COM]

Here is my code:

mail = '[e-mail]';   % false email for forum
password = 'password';     % false pass for forum
mailingList = {'[e-mail]'}; % false email for forum
server = 'smtp-mail.outlook.com';     
props = java.lang.System.getProperties;
props.setProperty('mail.smtp.port','587');
props.setProperty('mail.smtp.starttls.enable','true');
setpref('Internet','E_mail',mail);
setpref('Internet','SMTP_Server',server);
setpref('Internet','SMTP_Username',mail);
setpref('Internet','SMTP_Password',password);
messageBody = sprintf('   Good morning team!');
messageBody = sprintf('%s\n\n   Here is the data analysis from yesterdays data. Have a great day!', messageBody);
messageBody = sprintf('%s\n\n   - Brian Gregory', messageBody);
messageBody = sprintf('%s\n\n\n   *This email was generated and sent automatically via MATLAB', messageBody);
sendmail(mailingList, ...
    "Data Analysis - "+date, ...
    messageBody,fileDir7);

You probably have to re-enable the feature in your email account (more info for gmail).

If you're using gmail, the link to enable less secure app acces: https://myaccount.google.com/lesssecureapps

Make sure it's turned on.

If that's not the problem I'll remove this answer so your questions is recategorized as unanswered.

Thank you!

That feature has turned off once on me too. It's probably an internal safety feature of gmail.

[Brian Gregory]

Yeah I was using outlook but I couldn't figure this feature out on it so I made a gmail because it's easier to manage in my opinion.

If you aren't doing this already, I recommend creating an dedicated gmail account for this purpose that is isolated from your google profile. This opens the doors to security problems but there's no way around it.
