Reading Emails from outlook in C#

Hi, hope you are well.
Junior dev here. I am trying to figure out how to get my C# application to read emails from a certain address, if it matches then check if it has an attachment. IF it does extract the attachment and store it locally. I can not get past the logging in of my account.
//Code in my Program class
string email = "xxx";
string password = "xxx";
string host = "outlook.live.com";
int port = 995;
var emailHandling = new EmailHandling(email, password);
emailHandling.DownloadAttachment(host, port, savePath);

//Class for the handling
public class EmailHandling {

private readonly string email;

private readonly string password;

public EmailHandling(string email, string password) {

  this.email = email;

  this.password = password;  }

public async void DownloadAttachment(string host, int port, string savePath) {

  try  {

    using (var client = new ImapClient()) // creating an instance of ImapClient  {

      using (var cancel = new CancellationTokenSource())  {

        client.Connect(host, port, SecureSocketOptions.Auto); // Estabishing a connection 

        client.AuthenticationMechanisms.Remove("XOAUTH2");

        client.AuthenticationMechanisms.Remove("PLAIN");

        client.AuthenticationMechanisms.Remove("LOGIN");

        client.Authenticate(email, password, cancel.Token); // Supplying the auth with credentials

        var inbox = client.Inbox; // Opening the Inbox folder only

        inbox.Open(MailKit.FolderAccess.ReadOnly); // Permission to readonly 

        var uniqueIds = inbox.Search(SearchQuery.New)  // Search for the most recent emails

                        .OrderByDescending(x => x.Id)

                        .Take(3);

        foreach (var uniqueId in uniqueIds)  {

          var message = inbox.GetMessage(uniqueId);

          // Check if the email is from ******@dhl.com

          if (message.From.Mailboxes.Any(m => m.Address.Equals("xxx", StringComparison.OrdinalIgnoreCase)))  {

            foreach (var attachment in message.Attachments) // Looping through the attachments  {

              if (attachment is MimePart part && part.FileName.EndsWith(".zip", StringComparison.OrdinalIgnoreCase)) // Mimepart is how the body content have to check that for the attachment {

                var fileName = Path.Combine(savePath, part.FileName);

                using (var stream = File.Create(fileName))  {

                  part.Content.DecodeTo(stream); }

                Console.WriteLine($"Attachment saved: {fileName}");  } } } }

        client.Disconnect(true);  }}}

  catch (AuthenticationException ex)  {

    Console.WriteLine("Authentication failed.");

    Console.WriteLine(ex.Message);  }

  catch (Exception ex) {

    Console.WriteLine("An error occurred while downloading the attachment.");

    Console.WriteLine(ex.Message);  } } } }  
```If this helps I am trying to build it in .net 6 core
