Win32::OLE works great for accessing Outlook from Perl, with the below iterating over all the messages in your Inbox (but possibly not sub-folders).
#!perl
use strict;
use warnings;
use Win32::OLE 'in';
use Win32::OLE::Const 'Microsoft Outlook'; # olFolderInbox
my $outlook = Win32::OLE->GetActiveObject('Outlook.Application')
or do {
my $reason = Win32::FormatMessage(Win32::GetLastError());
die "Cannot get active Outlook object: $reason";
};
my $namespace = $outlook->GetNamespace('MAPI');
if (my $folder = $namespace->GetDefaultFolder(olFolderInbox)) {
print $folder->Name, "\n";
foreach my $email (in $folder->Items) {
print " ", $email->Subject, "\n"
if $email->Subject eq 'Build 50.2';
# Do something with $email.
}
}
However, if you do plan on doing something further with $email once you've found the right message, it is essential that you use ActivePerl's OLE browser, thumb through the MSDN Library and/or Google liberally for example usage as knowing what to access or look for in the OLE objects is 99% of the battle!
Update: s/ eq /\n if $email->Subject eq /; # oops
