Aspose.Email for .NET 24.5 (DLLs-only package) brings exciting new features and enhancements to take your email processing applications to the next level. This update focuses on improved functionality for working with PST files within your C# email processing apps.

Extract Message Recipients from PST

This update to the C# email API enables easy retrieval of recipients associated with messages within PST files using entry IDs or message information.

Please check out the following code example, which showcases the extraction of recipients with an entry ID using the MapiRecipientCollection ExtractRecipients(string entryId) method.

using (var pst = PersonalStorage.FromFile(fileName))
{  
    // Recipients are extracted using the entry ID
    var recipients = pst.ExtractRecipients("AAAAADzSMygQQFJOkKwVhb8v5EUkASAA");
}

This code sample illustrates how to extract recipients from message info using the MapiRecipientCollection ExtractRecipients(MessageInfo messageInfo) method.

using (var pst = PersonalStorage.FromFile(fileName))
{  
    // The "Inbox" folder is obtained
    var folder = pst.RootFolder.GetSubfolder("Inbox");

    // Each message in the "Inbox" folder is iterated
    foreach (var messageInfo in folder.EnumerateMessages())
    {
        // Recipients are extracted from each message
        var recipients = pst.ExtractRecipients(messageInfo);
    }
}

Recover Soft Deleted Items in Local PST and OST Files

.NET developers can now restore accidentally deleted emails and other items from local PST and OST archives. This code example highlights the recovery of soft deleted items using the IList<RestoredItemEntry> FindAndExtractSoftDeletedItems() method.

using (var pst = PersonalStorage.FromFile(fileName))
{
    // Soft deleted items are found and extracted
    var entries = pst.FindAndExtractSoftDeletedItems();

    // The recovered items are iterated through
    for (var index = 0; index < entries.Count; index++)
    {
        // Folder information is obtained by ID
        var folderInfo = pst.GetFolderById(entries[index].FolderId);

        // A directory for the folder is created if it doesn't exist
        if (!Directory.Exists(folderInfo.DisplayName))
        {
            Directory.CreateDirectory(Path.Combine(path, folderInfo.DisplayName));
        }
        
        // The restored item is obtained
        var msg = entries[index].Item;
        
        // The restored item is saved as a .msg file
        msg.Save(Path.Combine(path, folderInfo.DisplayName, $"{index}.msg"));
    }
}
