I subscribe to a mailing list and receive daily digests, formatted according
to RFC 1153. How can I split a digest into its individual messages?
But it's not really individual messages. It's just one big message that looks
to your eye like it contains multiple messages because you're assigning
meaning (that doesn't exist on the mail client level) to what you see in the
message body. Outlook has no method to do what you want. It's conceivable
that if you save it to a file external to Outlook (text, perhaps), that
there's a tool on the Internet that can split it apart, but you'll have to
look because I don't know of any. You could also write your own.
