Hi,
Please find attached sample MSG file. This is the source/ input MSG file. This MSG file contains 5-different types of attachment files.
I need to compress each attachment files into .zip file and then replace the attachments in MSG file.

Please note that Aspose.Email does not provide APIs to compress the attachments. However, you can extract the attachments from MSG file using Aspose.Email and ZIP them using Aspose.ZIP. Please read the following article.

Once you ZIP the extracted files, you can add them to MSG as attachment. Please read the following article to add attachment.

Hello,

I understand your points and I manage to extract and zip every attachments properly… My initial query is about how to attach .zip attachments using MapiMessage.

I don’t want to convert MapiMessage to MailMessage and then attach the attachments and then again convert MailMessage to MapiMessage.

Can you please assist me how to add attachments using MapiMessage?

Kind Regards,
