Extract emails from remote server via POP IMAP or Exchange Web Services protocols

GroupDocs.Parser provides the functionality to extract emails from remote servers. The following email protocols are supported:

  • Post Office Protocol (POP)
  • Internet Message Access Protocol (IMAP)
  • Exchange Web Services (EWS)

To create an instance of Parser class to extract emails from a remote server the following constructor is used:

Parser(EmailConnection connection);
Parser(EmailConnection connection, ParserSettings parserSettings)

The second constructor allows to use ParserSettings object to control the process; for example, by adding logging functionality.

EmailConnection is a base class. The following connection classes are used:

Exchange Web ServicesEmailEwsConnection

Here are the steps to extract emails from the remote server:

  • Prepare connection string (see table below);
  • Instantiate Parser object with connection string;
  • Call isContainer property to check if container extraction is supported;
  • Call getContainer method and obtain collection of ContainerItem objects;
  • Iterate through the collection and get Parser object for each item.

The following example shows how to extract emails from Exchange Server:

// Create the connection object for Exchange Web Services protocol
EmailConnection connection = new EmailEwsConnection(
// Create an instance of Parser class to extract emails from the remote server
try (Parser parser = new Parser(connection)) {
    // Check if container extraction is supported
    if (!parser.getFeatures().isContainer()) {
        System.out.println("Container extraction isn't supported.");
    // Extract email messages from the server
    Iterable<ContainerItem> emails = parser.getContainer();
    // Iterate over attachments
    for (ContainerItem item : emails) {
        // Create an instance of Parser class for email message
        try (Parser emailParser = item.openParser()) {
            // Extract the email text
            try (TextReader reader = emailParser.getText()) {
                // Print the email text
                System.out.println(reader == null ? "Text extraction isn't supported." : reader.readToEnd());
