Exporting mail from Gnus to MS Outlook?

[Rodolfo Medina]

Hi, Gnus users.

I need to transmit a stock of messages, a very big one,
to an MS Windows user.
In place of sending them to him, I wish to simply export them (if possible)
into a format that MS Outlook can collect and import inside its folders.
Does anybody know if and how is it possible to do such a thing?

Any suggestion very much appreciated.
Cheers,
Rodolfo
