access outlook 365 inbox [duplicate]

I have a piece of Java code (see below), which has not been changed in a while and worked two weeks ago. When I run it now, I suddenly get an "AUTHENTICATE FAILED." I get the error on two different PCs, and I have validated that the credentials used still work when I log into may office365 mailbox using the browser.
Has something changed on the office365 side I should know of?
The error I get is:
javax.mail.AuthenticationFailedException: AUTHENTICATE failed.
at com.sun.mail.imap.IMAPStore.protocolConnect(IMAPStore.java:732)
at javax.mail.Service.connect(Service.java:366)
at javax.mail.Service.connect(Service.java:246)
at my.application.input.imap.ImapMailBoxReader.processOnMessages(ImapMailBoxReader.java:69)
Digging deeper, the cause seems to be an A3 NO AUTHENTICATE failed. response (line 730 of javax.mail.IMAPStore).
The code I use is the following (using javax.mail version 1.6.2):
package my.application.input.imap;

Again, this code worked perfectly two weeks ago, nothing was changed on my side and the credentials still work...
All suggestions are appreciated.

You must use OAuth2, legacy security may have been deprecated.
Works with Thunderbird for example.
Just see how to reactivate legacy auth or use OAuth2 with your java client.
#see https://learn.microsoft.com/fr-fr/exchange/troubleshoot/administration/cannot-connect-mailbox-pop-imap-outlook to reactivate legacy
PS : To use shared mailbox, you must user mailbox name as user, and OAuth2 user + password and MFA if needed during Auth part, all that instead of old way (user#domain\sharedmailbox + password)

FakeFtpServer error: Connection refused (Connection refused)

I have a class that downloads files from FTP servers using the Apache FTP Client, and I want to test it. For doing so, I decided to use the FakeFtpServer class from MockFtpServer, but it always fails with the same error: Connection refused (Connection refused).
My test class:
public class FTPConnectionTest {
/** Mock FTP Server */
private static FakeFtpServer FAKE_FTP_SERVER;
/** Mock FTP Server address */
private static String ADDRESS = "localhost";
/** Mock FTP server user name */
private static String USERNAME = "ftpuser";

private static String ROOT;
/** Mock FTP Server port */
private static int PORT = 0;
/** Test directory in the mock server */
private static String DIRECTORY = "/directory";
/** Test file 1*/
private static String FILE1 = "/Human_satellite.txt";
/** Content of test file 1 */
private static String FILE1_CONTENT = "Ground control to Major Tom...";
/** Test file 1*/
private static String FILE2 = "/wall-e.txt";
/** Content of test file 1 */
private static String FILE2_CONTENT = "If lost in space, use fire extinguisher";
/** Test file 1*/
private static String FILE3 = "/buzz_lightyear.txt";
/** Content of test file 1 */
private static String FILE3_CONTENT = "To infinity, and beyond !";
/**

*/
#BeforeClass
public static void setupMock() {
// Create Mock server
FAKE_FTP_SERVER = new FakeFtpServer();
FAKE_FTP_SERVER.setServerControlPort(0); // Automatically finds available port
PORT = FAKE_FTP_SERVER.getServerControlPort();
FAKE_FTP_SERVER.addUserAccount(new UserAccount(USERNAME, PASSWORD, ROOT));
// Get the path to the resources folder where to run the mock FTP
File mockDir = new File("src/test/resources/ftp/mock");
ROOT = mockDir.getAbsolutePath();
// Create mock files
FileSystem fileSystem = new UnixFakeFileSystem();
fileSystem.add(new DirectoryEntry(ROOT));
fileSystem.add(new FileEntry(ROOT + FILE1, FILE1_CONTENT));
fileSystem.add(new DirectoryEntry(ROOT + DIRECTORY));
fileSystem.add(new FileEntry(ROOT + DIRECTORY + FILE2, FILE2_CONTENT));
fileSystem.add(new FileEntry(ROOT + DIRECTORY + FILE3, FILE3_CONTENT));
FAKE_FTP_SERVER.setFileSystem(fileSystem);
FAKE_FTP_SERVER.start();
}
/**
* The the mock FTP Server once the tests are done
*/
#AfterClass
public static void stop() {
FAKE_FTP_SERVER.stop();
}
/**

*/
#Test
public void testFetchNewFiles () {
// Get output path
String outputPath = "src/test/resources/ftp/result";
File output = new File(outputPath);
outputPath = output.getAbsolutePath();
// Create the connection and get the files
FTPConnection conn = new FTPConnection(ADDRESS, PORT, USERNAME, PASSWORD, outputPath);
conn.fetchNewFiles();
// Check that the files have bin downloaded
File file1 = new File(outputPath + FILE1);
assertTrue(file1.exists());
}
}
And here is the part of the FTP class that fails:
public class FTPConnection {
/** Logger */
private Logger logger;

private FTPClient client;

private String server;

this.output = output;
this.client = new FTPClient();
}
/**

public FTPConnection (String server, String user, String password, String output) {
this(server, 21, user, password, output);
}
public void fetchNewFiles() {

try {

this.client.login(user, password);
} catch (IOException e) {
logger.error("Error while connecting to FTP server '" + this.server + "': " + e.getMessage());
e.printStackTrace();
return;
}
}
}
And finally an extract of what's going on in the console:
19:24:31.417 [Thread-1] INFO org.mockftpserver.fake.FakeFtpServer - Starting the server on port 0
19:24:31.419 [Thread-1] INFO org.mockftpserver.fake.FakeFtpServer - Actual server port is 34003
19:24:31.444 [main] ERROR com.my.project.importHandler.FTPConnection - Error while connecting to FTP server 'localhost': Connection refused (Connection refused)

19:24:31.457 [Thread-1] INFO org.mockftpserver.fake.FakeFtpServer - Server stopped.

Ok, I found it: FAKE_FTP_SERVER.setServerControlPort(0); sets the value of the server port to 0, and the automatic selection of an available port only happens during FAKE_FTP_SERVER.start();. I moved the line PORT = FAKE_FTP_SERVER.getServerControlPort(); after FAKE_FTP_SERVER.start(); and now it works.

c3p0 access denied for user 'root'#'localhost' (using password yes)

I can't seem to connect a database using c3p0 when I use:
DriverManager.getConnection("jdbc:mysql://localhost:3306/rdmssql", "root", "");
no exception is thrown.
However, when I try to connection using the c3p0 connection pool:
private ComboPooledDataSource connectionPool;
...other code
/**
*
* #return
* #throws Exception
*/
public Connection getConnection() throws Exception {
return getInstance().connectionPool.getConnection();
}
/**

private void setConnectionDetails(String driver, String hostname, String databaseName, String username, String pwd) throws Exception, PropertyVetoException {
connectionPool.setDriverClass("com.mysql.jdbc.Driver");
connectionPool.setJdbcUrl(driver + "://" + hostname + "/" + databaseName);
connectionPool.setUser(username);
connectionPool.setPassword(pwd);
// the settings below are optional -- c3p0 can work with defaults
// will work on this in the future
connectionPool.setInitialPoolSize(5);
connectionPool.setMinPoolSize(5);
connectionPool.setAcquireIncrement(5);
connectionPool.setMaxPoolSize(20);
connectionPool.setMaxStatements(180);
}
an java.sql.SQLException: Access denied for user: 'root#127.0.0.1' (Using password: YES) is thrown. I'm not sure if I missed some configurations for my c3p0.

The exception says it ('using password': YES).
The driver manager version does not use a password (and succeeds), whereas the connection pool version DOES (and fails).
Check the argument value passed to pwd (and make it send "").

Or if it is ftp,

Your password has "#".
You need escape, try replace "#" to "%40".

Your password contains a #, thus concatenation creates an invalid connection string: sftp://username:p#ssword#hostName
It must be encoded as sftp://username:p%40ssword#hostName
Instead of concatenation, create a java.net.URI to handle proper password encoding
String userInfo = user + ":" + passwd;
URI uri = new URI("sftp", userInfo, host, -1, path, null, null);

How to send an email using MS exchange server

I am trying to sent an email using my company's mail server. But I am getting the following exception
Caused by: com.sun.mail.smtp.SMTPSendFailedException: 530 5.7.1 Client was not authenticated
at com.sun.mail.smtp.SMTPTransport.issueSendCommand(SMTPTransport.java:1388)
at com.sun.mail.smtp.SMTPTransport.mailFrom(SMTPTransport.java:959)
at com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:583)
at javax.mail.Transport.send0(Transport.java:169)
at javax.mail.Transport.send(Transport.java:98)
Here is my sample code,
Properties props = System.getProperties();
// Setup mail server
props.put("mail.smtp.host", "example.server.com");
props.put("mail.smtp.auth", "true");
props.put("mail.debug", "true");
props.put("mail.smtp.port", "25");
// Get session
//Session session = Session.getDefaultInstance(props, null);
Session session = Session.getDefaultInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("username", "password");
}
});
// Define message
MimeMessage message = new MimeMessage(session);
// Set the from address
message.setFrom(new InternetAddress(from));
// Set the to address
message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
// Set the subject
message.setSubject("Hello JavaMail");
// Set the content
message.setText("Welcome to JavaMail");
// Send message
Transport.send(message);
What piece of code is wrong?
As as username and password , I am using my company's email address and password.

The 5.7.1 is probably caused by exchange and not your code. You may just need to enable relaying on the server. Either for anonymous users or from a certain IP address. I'm not an expert on Exchange but I have got this working before. Here is the last solution I tested that works:
If a 5.7.1 error is encountered when trying to send an email via SMTP on an exchange server when the user has been authenticated..
For ref the issue you just had was caused by a setting on the Exchange 2007 server – this would not normally be a problem on 2003 server
Fixed by doing below...
You can set this authentication setting via the GUI
In Server configuration / Hub Transport / Default <ServerName>
Right click, properties, Permission Groups
Check "Anonymous users" and then click OK
Obviously anon users is not too secure but you could see if this solves the problem.

When I will use a MS Exhange SMTP Server to send an email, I use the above maven dependency.
<dependency>
<groupId>com.microsoft.ews-java-api</groupId>
<artifactId>ews-java-api</artifactId>
<version>2.0</version>
</dependency>
For that reason I created a class that represents an email client for MS Exchange Servers. I use log4j for logging.
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>

A working example,

ExchangeClient client = new ExchangeClient.ExchangeClientBuilder()
.hostname("webmail.domainOfWeb.com")
.exchangeVersion(ExchangeVersion.Exchange2010)
.domain("ActiveDirectoryDomain")
.username("ActiveDirectoryUsername")
.password("ActiveDirectoryPassword")
.recipientTo("recipient#whatever.com")
.recipientCc("recipient#whatever.com") // Ignore it in case you will not use Cc recipients.
.recipientBcc("recipient#whatever.com") // Ignore it in case you will not use Bcc recipients.
.attachments("/home/username/image.png") // Ignore it in case you will not use attachements.
.subject("Test Subject")
.message("Test Message")
.build();
client.sendExchange();

Mail.jar (Version 1.4.0) has a compatibility issue with MS Exchange Server and throws 530 5.7.1 Client was not authenticated, even when Username and password are configured.
Upgrading the mail API to 1.4.4 OR 1.4.7 should resolve the issue.
Mail API's 1.4.7 can be download from the following URL: http://www.oracle.com/technetwork/java/javamail/index.html

In some companies, the Exchange server SMTP support is disable and you cannot ask them to enable it. In these cases, a reasonable solution is this one:

Simple Java Mail worked for me. The only thing you have to check is for correct hostname, username, port and password TransportStrategy.SMTP_TLS:
new Mailer(host, port, username, password, TransportStrategy.SMTP_TLS).sendMail(email);

I had to use javamail + exchange. The messages returned were helpless.
Thanks to the stack, I got some hints.
Add this to your code
props.put("mail.smtp.starttls.enable","true");
Think of adding the certificates of the machines used too.
To find them, just go to your browser, export them and import to the cacerts file in use.

Please use the following code parts instead of Transport.send(message);
MimeMessage message = new MimeMessage(session);
message.saveChanges();
Transport transport = session.getTransport("smtp");
transport.connect(host, "user", "pwd");
transport.sendMessage(message, message.getAllRecipients());
transport.close();
I have tested in the local and it is working

The ews-java-api package is at end of life.
From https://github.com/OfficeDev/ews-java-api
Starting July 19th 2018, Exchange Web Services (EWS) will no longer receive feature updates. While the service will continue to receive security updates and certain non-security updates, product design and features will remain unchanged. This change also applies to the EWS SDKs for Java and .NET. More information here: https://developer.microsoft.com/en-us/graph/blogs/upcoming-changes-to-exchange-web-services-ews-api-for-office-365/
