Hi,

objol = actxserver('outlook.Application'); 
objNameSpace = objol.GetNamespace('MAPI');   
objInbox = objNameSpace.GetDefaultFolder('olFolderInbox');  
objMails  = objInbox.Items;
objMail = objMails.GetFirst; % Use other methods to traverse through items
mailBody = objMail.Body;

t_filePath = fullfile(pwd, 'test.txt');
fid = fopen(t_filePath, "w");
if fid ~= -1
    fprintf(fid, "%s", mailBody);
    fclose(fid);
end

Thank you for your reply.

Is it possible to create a text file that includes the "header" of the email, such as the email subject, sending date and time, sender, and recipient?

The following will cause an error.

 objMails.Item(1).Save([t_filePath, '.txt'] , 'olTXT' )

Check the call to function 'Save' for incorrect argument data type or missing argument.

What you should look for is the Component Object Model (COM) (or API?) for Outlook and read what are the properties and methods available for particular class.

For example, class for mail is MailItem, here is a link https://learn.microsoft.com/en-us/office/vba/api/outlook.mailitem the properties that you are looking for are there. So you should construct string array or char array like in my answer above. For example:

if fid ~= -1
    fprintf(fid, "%s\n", objMail.SenderEmailAddress)
    fprintf(fid, "%s\n", objMail.Subject)
    fprintf(fid, "%s\n", objMail.ReceivedTime)
    fprintf(fid, "%s\n", objMail.Body)
    fclose(fid);
end

I haven't tested it, it might fail, but this is the general idea. You can optimize it by constructing a complete data first and then just use fprintf once to write the data to file as this way might be slow if you have to process a lot of data.
