Examples

The following code example shows how to create a message. Note that a message that is returned in a response will have many other properties that are set by the Exchange server.

static MessageType CreateMessage()
{ 
    // Create a meesage.
    MessageType <span class="label">message</span> = new MessageType();

    // Add recipients to message.
<span class="label">message</span>.ToRecipients = new EmailAddressType[2];
<span class="label">message</span>.ToRecipients[0] = new EmailAddressType();
<span class="label">message</span>.ToRecipients[0].EmailAddress = "user1@example.com";
<span class="label">message</span>.ToRecipients[1] = new EmailAddressType();
<span class="label">message</span>.ToRecipients[1].EmailAddress = "user2@example.com";
<span class="label">message</span>.CcRecipients = new EmailAddressType[1];
<span class="label">message</span>.CcRecipients[0] = new EmailAddressType();
<span class="label">message</span>.CcRecipients[0].EmailAddress = "user3@example.com";
<span class="label">message</span>.BccRecipients = new EmailAddressType[1];
<span class="label">message</span>.BccRecipients[0] = new EmailAddressType();
<span class="label">message</span>.BccRecipients[0].EmailAddress = "user4@example.com";

    // Compose e-mail message.
<span class="label">message</span>.Subject = "High Priority Projects for Q3";
<span class="label">message</span>.Body = new BodyType();
<span class="label">message</span>.Body.BodyType1 = BodyTypeType.HTML;
<span class="label">message</span>.Body.Value = "&lt;html&gt;&lt;body style='font-family: Arial'&gt;&lt;ul&gt;" +
     "&lt;li&gt;Create budget for next fiscal year.&amp;nbsp;&lt;/li&gt;" + 
     "&lt;li&gt;Hiring updates.&amp;nbsp;&lt;/li&gt;" + 
     "&lt;li&gt;Design plan for new facilities.&lt;/li&gt;" + 
     "&lt;li&gt;Identify new opportunities for operational efficiency.&amp;nbsp;&lt;/li&gt;" +
     "&lt;/ul&gt;&lt;p&gt;Please provide feedback before the meeting.&amp;nbsp;&lt;/p&gt;&lt;/body&gt;&lt;/html&gt;";
<span class="label">message</span>.Sensitivity = SensitivityChoicesType.Confidential;
<span class="label">message</span>.SensitivitySpecified = true;
<span class="label">message</span>.Categories = new string[2] { "Planning", "FiscalYear_Next" };
<span class="label">message</span>.Importance = ImportanceChoicesType.High;
<span class="label">message</span>.ImportanceSpecified = true;

    return <span class="label">message</span>;
}

Remarks

The MessageType class has many members that are read-only but that have a setter for the property. This is an artifact from the definition in the schema file. For example, the IsRead property cannot be set when you are creating a message. This property is returned when a message item is received in a response from the computer that is running Exchange Server 2007.

You do not have to set the ItemClass property on the MessageType object unless you want to create a custom subtype of IPM.Note. The Exchange server handles the MessageType as an IPM.Note.

MessageType objects represent e-mail messages and all other items that are not strongly typed by the Exchange Web Services (EWS) schema. Items such as IPM.Sharing and IPM.InfoPath are returned as MessageType objects. Versions of Exchange Server starting with Exchange 2010 and Exchange Online do not return the base ItemType object in responses.

Constructors

MessageType()

The MessageType constructor initializes a new instance of the MessageType class.
