Image not displayed in Outlook in ASP

After sending an email the logo is not displayed in Outlook but it works in Gmail.
I found that in the inspect element that the image src is changed into blockedimagesrc
In my Controller :
var NotifyCompany = new NotifyCompany()
{
Email = model.regE,
EmailTo = contact.GetPropertyValue<string>("email"),
DateRegistered = DateTime.UtcNow
};
EmailHelpers.SendEmail(NotifyCompany, "NotifyCompany", "New Client Registered");
Helpers :
public static ActionResponse SendEmail(IEmail model, string emailTemplate, string subject, List<HttpPostedFileBase> files = null)
{
try
{
var template =
System.IO.File.ReadAllText(HttpContext.Current.Server.MapPath(string.Format("~/Templates/{0}.cshtml", emailTemplate)));
var body = Razor.Parse(template, model);
var attachments = new List<Attachment>();
if (files != null && files.Any())
{
foreach (var file in files)
{
var att = new Attachment(file.InputStream, file.FileName);
attachments.Add(att);
}
}
var email = Email
.From(ConfigurationManager.AppSettings["Email:From"], "myWebsiteEmail")
.To(model.EmailTo)
.Subject(subject)
.Attach(attachments)
.Body(body).BodyAsHtml();
email.Send();
return new ActionResponse()
{
Success = true
};
}
catch (Exception ex)
{
return new ActionResponse()
{
Success = false,
ErrorMessage = ex.Message
};
}
}
In my Email Template :
<img src="/mysite.com/image/logo.png"/>
Any help would be appreciated.

Outlook web access will block any images by default - only if the user chooses to display/download images these will be displayed/downloaded. I am not sure if it is possible to adjust the default behavior by using office 365 admincenter or the OWA settings.
Some time ago it was possible to work around this by using it as a background image inside a table>tr>td cell background-image css property.
EDIT
Checked a recent project of myself, where we are sending notification mails about tickets. The site logo is displayed correctly in outlook/owa - without adding the recipient to the trusted list:
using (MailMessage mm = new MailMessage(sender, header.RecipientAddress, header.Subject, header.Body))
{
mm.Body = header.Body;
mm.BodyEncoding = Encoding.UTF8;
mm.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;
mm.Priority = priority == IntMailPriority.High ? MailPriority.High : MailPriority.Normal;
mm.IsBodyHtml = bodyIsHtml;
// logo
if (bodyIsHtml)
{
AlternateView htmlView = AlternateView.CreateAlternateViewFromString(header.Body, Encoding.UTF8, "text/html");
string logoPath = $"{AppDomain.CurrentDomain.BaseDirectory}\\images\\logo_XXX.png";
LinkedResource siteLogo = new LinkedResource(logoPath)
{
ContentId = "logoId"
};
htmlView.LinkedResources.Add(siteLogo);
mm.AlternateViews.Add(htmlView);
}
// create smtpclient
SmtpClient smtpClient = new SmtpClient(smtpSettings.ServerAddress, smtpSettings.Port)
{
Timeout = 30000,
DeliveryMethod = SmtpDeliveryMethod.Network
};
// set relevant smtpclient settings
if (smtpSettings.UseTlsSsl)
{
smtpClient.EnableSsl = true;
// needed for invalid certificates
ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };
}
if (smtpSettings.UseAuth)
{
smtpClient.UseDefaultCredentials = false;
NetworkCredential smtpAuth = new NetworkCredential { UserName = smtpSettings.Username, Password = smtpSettings.Password };
smtpClient.Credentials = smtpAuth;
}
smtpClient.Timeout = smtpSettings.SendingTimeout * 1000;
// finally sent mail \o/ :)
try
{
smtpClient.Send(mm);
}
catch (SmtpException exc)
{
throw new ProgramException(exc, exc.Message);
}
catch (InvalidOperationException exc)
{
throw new ProgramException(exc, exc.Message);
}
catch (AuthenticationException exc)
{
throw new ProgramException(exc, exc.Message);
}
}
Afterwards the logo is referred to as
<IMG alt="Intex Logo" src="cid:logoId">
inside the generated html.

Reading Multiple Outlook Email for multiple IDs in C#

Referring to the answer mentioned in the post:
Reading Outlook Mail with C#
This code works well for a single account, but the issue with the current code is that it reads the email of the default id which was set as the first one in the outlook app.
For example, if "abcxyz#outlook.com" is set as the first account and "decxyz#outlook.com" is set as the second one, then it reads the inbox of only the first id, i.e., "abcxyz#outlook.com". I tried doing some modifications in the code but it did not work. Below is my code:
public static void OutLookMailStart(string EmailID, string password)
{
Microsoft.Office.Interop.Outlook.Application app = null;
Microsoft.Office.Interop.Outlook._NameSpace ns = null;
Microsoft.Office.Interop.Outlook.PostItem item = null;
Microsoft.Office.Interop.Outlook.MAPIFolder inboxFolder = null;
Microsoft.Office.Interop.Outlook.MAPIFolder subFolder = null;
Microsoft.Office.Interop.Outlook.MailItem mailItem = null;
try
{
app = new Microsoft.Office.Interop.Outlook.Application();
ns = app.GetNamespace("MAPI");
ns.Logon(EmailID, password, false, true);
inboxFolder = ns.GetDefaultFolder(Microsoft.Office.Interop.Outlook.OlDefaultFolders.olFolderInbox);
foreach (Object mail in inboxFolder.Items)
{
if ((mail as MailItem) != null && (mail as MailItem).UnRead == true)
{
// Email Subject
string Subject = (mail as MailItem).Subject.ToString();
if (Subject.Contains(FileDomain))
{
// Email Body
var ReplyText = ExtractReply(((mail as MailItem).Body.ToString()), FromTrimName);
}
// (mail as MailItem).UnRead = false;
(mail as MailItem).Save();
}
}
}
catch (System.Exception ex)
{
throw ex;
}
finally
{
ns.Logoff();
inboxFolder = null;
subFolder = null;
mailItem = null;
app = null;
}}
Any sort of help will be appreciated.

Okay, so this is my code to retrieve emails. I wanted help regarding how I could authenticate the password I'll be passing as a parameter in:

Could someone help me out?

How to get all the messages from the Imapclient folder?

I intended to get all my messages in the Inbox folder and put them into the datagridview component.But the sentence "var message = client.Inbox.GetMessage(uids.Count - i - 1);" throws an exception:The IMAP server did not return the requested message. Is there anything wrong with my code?
//get a imapclient and connect to the server
string loginemail = UserInfo.LoginEmail;
string password = UserInfo.LoginPassword;
var client = new ImapClient();
client.Connect("imap.qq.com", 993, SecureSocketOptions.SslOnConnect);
client.Authenticate(loginemail, password);
client.Inbox.Open(FolderAccess.ReadOnly);
var uids = client.Inbox.Search(SearchQuery.All);
//get all the messages from the specified folder
for (int i = 0; i < uids.Count; i++)
{
dataGridView1.Rows.Add(1);
var message = client.Inbox.GetMessage(uids.Count - i - 1);
dataGridView1.Rows[i].Cells[0].Value = message.From.ToString();
if (message.Subject != null) { dataGridView1.Rows[i].Cells[1].Value = message.Subject.ToString(); }
else { dataGridView1.Rows[i].Cells[1].Value = ""; }
dataGridView1.Rows[i].Cells[2].Value = message.Date.ToString();
}

The only way to figure out the problem is to follow the directions in the MailKit FAQ to get a protocol log and look to see what the server is sending as a reply.

EAGetMail, How to read all emails from POP3 Gmail server?

I'm using EAGetMail library to read emails from Gmail.
This is my code:
private void readMails(){
MailServer oServer=new MailServer("pop.gmail.com", "something#gmail.com", "noneedtoseethis", ServerProtocol.Pop3);
MailClient oClient = new MailClient("Client");
oServer.SSLConnection = true;
oServer.Port = 995;
try {
oClient.Connect(oServer);
MailInfo[] infos = oClient.GetMailInfos();
Console.WriteLine(infos.Length);
for (int i = 0; i < infos.Length; i++){
MailInfo info = infos[i];
Mail oMail = oClient.GetMail(info);
Console.WriteLine("From: {0}", oMail.From.ToString());
//oClient.Delete(info);
}
oClient.Quit();
} catch (Exception ep) {
Console.WriteLine(ep.Message);
}
}
Though it appears the only thing that it gets are the new messages I receive which are 2 or 3 every five minutes.
But I want to read all emails I have in the inbox, not just the new coming messages
How can I do that?

Because Gmail POP3 server doesn't work like normal POP3 server, it hides old emails automatically even the email was not deleted, so I suggest that you use IMAP4 protocol, then you will read all emails.
just change:
server address to imap.gmail.com,
server port to 993,
ServerProtocol.Pop3 to ServerProtocol.Imap4
just like this:
private void readMails(){
MailServer oServer=new MailServer("imap.gmail.com", "something#gmail.com", "noneedtoseethis", ServerProtocol.Imap4);
MailClient oClient = new MailClient("Client");
oServer.SSLConnection = true;
oServer.Port = 993;
try {
oClient.Connect(oServer);
MailInfo[] infos = oClient.GetMailInfos();
Console.WriteLine(infos.Length);
for (int i = 0; i < infos.Length; i++){
MailInfo info = infos[i];
Mail oMail = oClient.GetMail(info);
Console.WriteLine("From: {0}", oMail.From.ToString());
//oClient.Delete(info);
}
oClient.Quit();
} catch (Exception ep) {
Console.WriteLine(ep.Message);
}
}
