CodeTwo Exchange Rules Pro enables automatic compression of attachments that are included in email messages. This is a useful feature if you want to attach a file to a message and its size is too large, especially when you do not want to store it on a public server. CodeTwo Exchange Rules Pro will automatically compress the attachment to reduce the file size and send the message.
