Hi Guhananth,

As jzero has said, you could use MailKit,

Below is a simple sample of MailKit, I use gmail and imap as a test.

 using (var client = new ImapClient())
                {
                    // For demo-purposes, accept all SSL certificates
                    client.ServerCertificateValidationCallback = (s, c, h, en) => true;

                    client.Connect("imap.gmail.com", 993, true);

                    client.Authenticate("[e-mail]", "yourmailpassword");

                    // The Inbox folder is always available on all IMAP servers...
                    var inbox = client.Inbox;
                    inbox.Open(FolderAccess.ReadWrite);
                 
                   Response.Write("Total messages: "+ inbox.Count+"<br/>");
                Response.Write("Recent messages:"+ inbox.Recent+"<br/>");

                  // get a folder and append the message into the folder
               var newFolder= client.GetFolder("Social");
                newFolder.Append(inbox.GetMessage(1));
                     
               // delete the first message
                client.Inbox.AddFlags(new int[] { 0}, MessageFlags.Deleted,true);
                    for (int i = 0; i < inbox.Count; i++)
                    {
                        var message = inbox.GetMessage(i);
                         //loop through the attachment of the message
                    foreach (var attachment in message.Attachments)
                    {
// save the attachment
                        var fileName = attachment.ContentDisposition?.FileName ?? attachment.ContentType.Name;

                        using (var stream = File.Create(fileName))
                        {
                            if (attachment is MessagePart)
                            {
                                var rfc822 = (MessagePart)attachment;

                                rfc822.Message.WriteTo(stream);
                           
                            }
                            else
                            {
                                var part = (MimePart)attachment;

                                part.Content.DecodeTo(stream);
                            }
                        }
                    }
                     // get the subject of the message
                    Response.Write( "subject:"+message.Subject+"<br/>");
                       // get   from of the message
                    Response.Write("address:" + message.From + "<br/>");
                    Response.Write("<br/><br/>");


                }

                    client.Disconnect(true);
                }

For EWS you can get more info here https://docs.microsoft.com/en-us/previous-versions/office/developer/exchange-server-2010/dd877037%28v%3dexchg.140%29
I already worked with EWS, all I can tell, there is not so much samples available, it uses a proper dialect, the way to work is not always clear and you need to have in mind it is a WebService.
