Signature Preservation and Removal

1. Signature preservation is now supported by default in mbox to pst conversion. Added a new MboxToPstConversionOptions.RemoveSignature property, to indicate whether the signature should be removed during conversion. You can set this property to true to remove the signature.

   • Added MboxToPstConversionOptions.RemoveSignature property.

   Example usage:

   var pstDataStream = new MemoryStream();
   var personalStorage = PersonalStorage.Create(pstDataStream, FileFormatVersion.Unicode);
   MailStorageConverter.MboxToPst(new MboxrdStorageReader(new FileStream(fileName, FileMode.Open, FileAccess.Read), new MboxLoadOptions()),
       personalStorage,
       "Inbox",
       new MboxToPstConversionOptions() { RemoveSignature = true });
   

2. Signature preservation is now supported by default when loading EML files. Added a new LoadOptions.RemoveSignature property, to indicate whether the signature should be removed during loading. You can set this property to true to remove the signature.

   Example usage:

   var msg = MapiMessage.Load(fileName, new EmlLoadOptions() { RemoveSignature = true});
