I doubt there is any special module for MS Exchange. But did you try Win32::OLE? If MS Exchange may be controled from VB(Script) using "automation" you may do the same from Perl. Just the syntax will be a little different.

I can't give you any examples, but you should be able to find examples of controling MSWord and MSExcel via Win32::OLE and that should give you a hint how this looks.

Sorry I can't be more specific, Jenda
