Add Message to PST File in C#, VB.NET

Written by support iceblue

In the previous article, we have introduced how to read a PST file and get the folder information from it. This article will show you how we can add existing mail message files into PSF file for archiving.

Step 1: Load a PST file from disk into an instance of OutlookFile class.

OutlookFile outlookFile = new OutlookFile(@"C:\Users\Administrator\Documents\Outlook Files\Sample.pst");

Step 2: Load a MSG file into an instance of OutlookItme class.

OutlookItem item = new OutlookItem();
item.LoadFromFile(@"C:\Users\Administrator\Documents\Outlook Files\Sample.msg");

Step 3: Get inbox folder from PST file.

OutlookFolder inboxFolder = outlookFile.RootOutlookFolder.GetSubFolder("Inbox");

Step 4: Add the MSG file to inbox folder.

inboxFolder.AddItem(item);

Full Code:

[C#]
OutlookFile outlookFile = new OutlookFile(@"C:\Users\Administrator\Documents\Outlook Files\Sample.pst");
OutlookItem item = new OutlookItem();
item.LoadFromFile(@"C:\Users\Administrator\Documents\Outlook Files\Sample.msg");
OutlookFolder inboxFolder = outlookFile.RootOutlookFolder.GetSubFolder("Inbox");
inboxFolder.AddItem(item);
Console.WriteLine("Completed");
[VB.NET]
Dim outlookFile As New OutlookFile("C:\Users\Administrator\Documents\Outlook Files\Sample.pst")
Dim item As New OutlookItem()
item.LoadFromFile("C:\Users\Administrator\Documents\Outlook Files\Sample.msg")
Dim inboxFolder As OutlookFolder = outlookFile.RootOutlookFolder.GetSubFolder("Inbox")
inboxFolder.AddItem(item)
Console.WriteLine("Completed")

Spire.Email supports to create Outlook message (MSG) files with rich text bodies and attachments in C# and VB.NET. The RTF body supports to set the formatting for the font, such as in bold, underline and set the color and add lists to the message body. It makes the outlook message vivid and clear to view. Here comes to the steps of how to use Spire.Email to create and save the Outlook message with RTF body and attachment in C#.

Step 1: Create an instance of MailMessage class and specify sender and recipient address.

MailAddress addressFrom = new MailAddress("daisy.zhang@e-iceblue.com", "Daisy Zhang");
MailAddress addressTo = new MailAddress("susanwong32@outlook.com");
MailMessage mail = new MailMessage(addressFrom, addressTo);

Step 2: Add the subject, message body and attachment of the message.

mail.Subject = "This is a test message";

string htmlString = @"
   <p>Dear Ms. Susan,</p>
   <p>This is an example of creating an <b>outlook message</b> <u>(msg)</u>.</p>
   <ul>
   <li> Create a message with RTF file </li>
   <li> Create a message with attachment</li>
   </ul>
   <p style='color:red'>This text is in red </p>
   
   <p>Best regards, </p>
   <p>Daisy </p>";  
 mail.BodyHtml = htmlString;
 
 mail.Attachments.Add(new Attachment("logo.png"));

Step 3: Save the message as MSG format.

mail.Save("Sample.msg", MailMessageFormat.Msg);

Effective screenshot:

Full codes:

MailAddress addressFrom = new MailAddress("daisy.zhang@e-iceblue.com", "Daisy Zhang");
 MailAddress addressTo = new MailAddress("susanwong32@outlook.com");

 MailMessage mail = new MailMessage(addressFrom, addressTo);

 mail.Subject = "This is a test message";
 string htmlString = @"
   <p>Dear Ms. Susan,</p>
   <p>This is an example of creating an <b>outlook message</b> <u>(msg)</u>.</p>
   <ul>
   <li> Create a message with RTF file </li>
   <li> Create a message with attachment</li>
   </ul>
   <p style='color:red'>This text is in red </p>
   
   <p>Best regards, </p>
   <p>Daisy </p>";  
        
 mail.BodyHtml = htmlString;
               
 mail.Attachments.Add(new Attachment("logo.png"));

 mail.Save("Sample.msg", MailMessageFormat.Msg);

The PST files are used to store information that pertains to the e-mail folders, addresses, contact information, email messages and other data that is saved within Outlook and Exchange programs. Spire.Email supports to read PST files and get the folder information such as folder name, message count and unread message count.

Step 1: Load a PST file from disk into an instance of OutlookFile class.

OutlookFile olf = new OutlookFile(@"C:\Users\jack\Documents\Outlook Files\Sample.pst");

Step 2: Get the folders collection.

OutlookFolderCollection folderCollection = olf.RootOutlookFolder.GetSubFolders();

Step 3: Traverse the collection and get the folder information of each element in the collection.

foreach (OutlookFolder folder in folderCollection)
{
    Console.WriteLine("Folder: " + folder.Name);
    Console.WriteLine("Total items: " + folder.ItemCount);
    Console.WriteLine("Total unread items: " + folder.UnreadItemCount);
    Console.WriteLine("Whether this folder has subfolders: {0}", (folder.HasSubFolders)?"Yes":"No");
    Console.WriteLine("------------------Next Folder--------------------");
}

Output:

Get Folder Information from PST File in C#, VB.NET

Full Code:

[C#]
OutlookFile olf = new OutlookFile(@"C:\Users\jack\Documents\Outlook Files\Sample.pst");
OutlookFolderCollection folderCollection = olf.RootOutlookFolder.GetSubFolders();

foreach (OutlookFolder folder in folderCollection)
{
    Console.WriteLine("Folder: " + folder.Name);
    Console.WriteLine("Total items: " + folder.ItemCount);
    Console.WriteLine("Total unread items: " + folder.UnreadItemCount);
    Console.WriteLine("Whether this folder has subfolders: {0}", (folder.HasSubFolders)?"Yes":"No");
    Console.WriteLine("------------------Next Folder--------------------");
}
Console.WriteLine("Completed");
[VB.NET]
Dim olf As New OutlookFile("C:\Users\jack\Documents\Outlook Files\Sample.pst")
Dim folderCollection As OutlookFolderCollection = olf.RootOutlookFolder.GetSubFolders()

For Each folder As OutlookFolder In folderCollection
    Console.WriteLine("Folder: " + folder.Name)

    Console.WriteLine("Total items: " + folder.ItemCount)
	Console.WriteLine("Total unread items: " + folder.UnreadItemCount)
	Console.WriteLine("Whether this folder has subfolders: {0}", If((folder.HasSubFolders), "Yes", "No"))
	Console.WriteLine("------------------Next Folder--------------------")
Next
Console.WriteLine("Completed")

Send Bulk Emails in C#, VB.NET

Written by support iceblue

Sending bulk emails means that you can send a batch of emails to multiple recipients and they will not be able to determine the others you've sent the message to.

The following code snippets demonstrate how to send bulk emails using Spire.Email in C# and VB.NET.

Step 1: Create instances of MailMessage class and specify sender and recipients.

MailMessage message1 = new MailMessage("sender@e-iceblue.com", "recipient1@e-iceblue.com");
MailMessage message2 = new MailMessage("sender@e-iceblue.com", " recipient2@e-iceblue.com");
MailMessage message3 = new MailMessage("sender@e-iceblue.com", " recipient3@e-iceblue.com");

Step 2: Set the subject and body text of the messages.

message1.Subject = message2.Subject = message3.Subject = "Subject";
message1.BodyText = message2.BodyText = message3.BodyText = "This is body text.";

Step 3: Initialize an object of MailMessageCollection class and add the instances of MailMessage class into the object.

List msgs = new List();
msgs.Add(message1);
msgs.Add(message2);
msgs.Add(message3);

Step 4: Create a SmtpClient instance with host, port, username and password, and send batch of emails using SendSome method.

SmtpClient client = new SmtpClient();
client.Host = "smtp.outlook.com";
client.Port = 587;
client.Username = "sender@e-iceblue.com";
client.Password = "password";
client.ConnectionProtocols = ConnectionProtocols.Ssl;
client.SendSome(msgs);
Console.WriteLine("Message sent");

Full Code:

[C#]
MailMessage message1 = new MailMessage("sender@e-iceblue.com", "recipient1@e-iceblue.com");
MailMessage message2 = new MailMessage("sender@e-iceblue.com", " recipient2@e-iceblue.com");
MailMessage message3 = new MailMessage("sender@e-iceblue.com", " recipient3@e-iceblue.com");
message1.Subject = message2.Subject = message3.Subject = "subject";
message1.BodyText = message2.BodyText = message3.BodyText = "This is body text.";

List msgs = new List();
msgs.Add(message1);
msgs.Add(message2);
msgs.Add(message3);

SmtpClient client = new SmtpClient();
client.Host = "smtp.outlook.com";
client.Port = 587;
client.Username = "sender@e-iceblue.com";
client.Password = "password";
client.ConnectionProtocols = ConnectionProtocols.Ssl;
client.SendSome(msgs);
Console.WriteLine("Message sent");
[VB.NET]
Dim message1 As New MailMessage("sender@e-iceblue.com", "recipient1@e-iceblue.com")
Dim message2 As New MailMessage("sender@e-iceblue.com", " recipient2@e-iceblue.com")
Dim message3 As New MailMessage("sender@e-iceblue.com", " recipient3@e-iceblue.com")
message1.Subject = InlineAssignHelper(message2.Subject, InlineAssignHelper(message3.Subject, "subject"))
message1.BodyText = InlineAssignHelper(message2.BodyText, InlineAssignHelper(message3.BodyText, "This is body text."))

Dim msgs As New List(Of MailMessage)()
msgs.Add(message1)
msgs.Add(message2)
msgs.Add(message3)

Dim client As New SmtpClient()
client.Host = "smtp.outlook.com"
client.Port = 587
client.Username = "sender@e-iceblue.com"
client.Password = "password"
client.ConnectionProtocols = ConnectionProtocols.Ssl
client.SendSome(msgs)
Console.WriteLine("Message sent")
