Advanced Query Search (AQS) search with EWSClient

Advanced Query Syntax (AQS) is the query syntax used by Exchange as an alternative to searching filters for expressing search criteria. AQS is a more flexible way to perform searches and deliver search results for all commonly used fields on the items. AQS is also user-friendly and easy to understand and quickly mastering. Using AQS is suitable for finding messages by attachments and recipients.

We have added the following classes to perform AQS search queries in Exchange:

• ExchangeAdvancedSyntaxQueryBuilder - represents the builder of search expression based on the Advanced Query Syntax (AQS).
• ExchangeAdvancedSyntaxMailQuery - implements an Advanced Query Syntax (AQS) search that is used by EWS.

Create a search query using query builder:

 using (IEWSClient client = EWSClient.GetEWSClient(exchangeMailboxUri, name, password))

{

    ExchangeAdvancedSyntaxQueryBuilder advancedBuilder = new ExchangeAdvancedSyntaxQueryBuilder();

    advancedBuilder.From.Equals("Jim Martin");

    advancedBuilder.Subject.Contains("report");

    advancedBuilder.HasAttachment.Equals(true);

    ExchangeMessageInfoCollection messages = client.ListMessages(client.MailboxInfo.InboxUri, advancedBuilder.GetQuery());

}

Сreate a search query directly by using AQS:

  using (IEWSClient client = EWSClient.GetEWSClient(exchangeMailboxUri, name, password))

{

    ExchangeAdvancedSyntaxMailQuery query = new ExchangeAdvancedSyntaxMailQuery("subject:(product AND report)");

    ExchangeMessageInfoCollection messages = client.ListMessages(client.MailboxInfo.InboxUri, query);

}

See the syntax description.

Render custom icons in message attachment while HTML conversion

Sometimes, the message contains in-line attachments, that are shown up as icon images in a message body. Such messages may create problems while converting them to HTML, since the icon images are lost. This is because attachment’s icons are not held directly in the message.

We have fixed this problem so that the user can customize the icons for attachments when converting the message to HTML. For that, the HtmlSaveOptions.ResourceHtmlRendering event has been added added:

  var options = new HtmlSaveOptions();

options.ResourceHtmlRendering += SetAttachmentIcon;

options.ResourceRenderingMode = ResourceRenderingMode.SubstituteFromFile;

string fileName ="message.msg";

var mailMessage = MailMessage.Load(fileName);

mailMessage.Save(fileName + ".html", options);

 private static void SetAttachmentIcon(object sender, ResourceHtmlRenderingEventArgs e)

{

    AttachmentBase attachment = sender as AttachmentBase;

    e.Caption = attachment.ContentType.Name;

   if (attachment.ContentType.Name.EndsWith(".pdf"))

   {

        e.PathToResourceFile = "pdf_icon.png";

   }

   else if (attachment.ContentType.Name.EndsWith(".docx"))

   {

        e.PathToResourceFile = "word_icon.jpg";

   }

   else if (attachment.ContentType.Name.EndsWith(".jpg"))

   {

        e.PathToResourceFile = "jpeg_icon.png";

   }

   else

   {

        e.PathToResourceFile = "not_found_icon.png";

   }

}

Get Email Category in MHTML

We have introduced the ability to add a category header while converting message to MHML.

 MapiMessage msg = new MapiMessage("[e-mail]", "[e-mail]", "subj", "body");

msg.Categories = new string[] { "Urgently", "Important" };

MhtSaveOptions saveOptions = new MhtSaveOptions();

saveOptions.FormatTemplates[MhtTemplateName.Categories] = saveOptions.FormatTemplates[MhtTemplateName.Categories].Replace("Categories", "Les catégories");

saveOptions.RenderingHeaders.Add(MhtTemplateName.Categories);

msg.Save(fileName + ".mhtml", saveOptions);
