2. When you say storing this in a directory structure, do you mean on a different machine or on the Exchange server?

If you just want to download the messages, strip the attachments and store them locally this can be done with something like Email::Mime::Attachment::Stripper:

my $message_count  = $server->select( 'folder' );

print "Found $message_count messages\n";
foreach my $message_number ( 1 .. $message_count ) {
    print "Processing message number $message_number\n";

    my $email = Email::MIME->new( join '', @{$server->get( $message_nu
+mber )} );

    my $stripper = Email::MIME::Attachment::Stripper->new($email);
    my @attachments = $stripper->attachments;

    foreach my $attachment ( @attachments ) {
        print $attachment->{filename}, " ", $attachment->{content_type
+}, "\n";
    }
}

In my brief experience I haven't had problems using similar code to access an Exchange server in the past (although the code above is untested as I don't have access to that code right now) other than dealing with ms-tnef attachments from Outlook users sending RTF messages..

3. Suggestions on handling this depend more on your requirements. You can always append the date/time of the message you are processing to the attachment name or perhaps see if an attachment by the name you have already exists and append a number to the end etc..

Hope that helps!
