Published: 29 Dec 2011 By Sher Azam

This technical tip shows how to download Messages from Public Folders of Exchange Server. Microsoft Exchange Server provides the facility to create public folders and post messages in it. You can use ExchangeWebServiceClient class of Aspose.Email to connect to the Exchange Server and read/download messages and posts from Exchange public folders. Below is the sample source code to read all public folders/sub-folders and list/download messages inside these folders.

[C#]
 
class Program
{
    static string mailboxURI = "https://ex2010/ews/exchange.asmx"; // EWS
    static string username = "administrator";
    static string password = "pwd";
    static string domain = "ex2010.local";
 
    
    static void Main(string[] args)
    {
        try
        {
            ReadPublicFolders();
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
    }
 
    private static void ReadPublicFolders()
    {
        NetworkCredential credential = new NetworkCredential(username, password, domain);
        ExchangeWebServiceClient client = new ExchangeWebServiceClient(mailboxURI, credential);
 
        ExchangeFolderInfoCollection folders = client.ListPublicFolders();
        foreach (ExchangeFolderInfo publicFolder in folders)
        {
            Console.WriteLine("Name: " + publicFolder.DisplayName);
            Console.WriteLine("Subfolders count: " + publicFolder.ChildFolderCount);
            ListMessagesFromSubFolder(publicFolder, client);
            
        }
    }
 
    private static void ListMessagesFromSubFolder(ExchangeFolderInfo publicFolder, ExchangeWebServiceClient client)
    {
        Console.WriteLine("Folder Name: " + publicFolder.DisplayName);
        ExchangeMessageInfoCollection msgInfoCollection = client.ListMessagesFromPublicFolder(publicFolder);
        foreach (ExchangeMessageInfo messageInfo in msgInfoCollection)
        {
            MailMessage msg = client.FetchMessage(messageInfo.UniqueUri);
            Console.WriteLine(msg.Subject);
            msg.Save(msg.Subject + ".msg", MailMessageSaveType.OutlookMessageFormat);
        }
 
        // Call this method recursively for any subfolders
        if (publicFolder.ChildFolderCount > 0)
        {
            ExchangeFolderInfoCollection subfolders = client.ListSubFolders(publicFolder);
            foreach (ExchangeFolderInfo subfolder in subfolders)
            {
                ListMessagesFromSubFolder(subfolder, client);
            }
        }
    }
}
