You need to read more about the objects you're using. For eaxmple,
my $Item = $client_folder->Items;
should be
foreach my $Item (in $client_folder->Items) {

in is imported using use Win32::OLE qw( in );

Update: According to Errto, 

my $Item = $client_folder->Items;
my $last_email = $Item->GetLast();

[download]

is functionally correct, but would be more accurate as 

my $Items = $client_folder->Items;
my $last_email = $Items->GetLast();

[download]

or simply 

my $last_email = $client_folder->Items->GetLast();
