What are best practices for handling authentication errors when connecting to an Exchange server using PHP?

When connecting to an Exchange server using PHP, it is important to handle authentication errors properly to ensure secure and reliable communication. One best practice is to catch and handle any authentication errors that may occur during the connection process, providing informative error messages to the user or logging the errors for troubleshooting purposes. 

try {
    // Connect to Exchange server
    $connection = new ExchangeConnection($server, $username, $password);
    $connection->open();

    // Perform operations on the Exchange server

    $connection->close();
} catch (AuthenticationException $e) {
    // Handle authentication errors
    echo "Authentication failed: " . $e->getMessage();
} catch (Exception $e) {
    // Handle other exceptions
    echo "An error occurred: " . $e->getMessage();
}
