Using classic Outlook for Windows in business environments
I do not what you require and from who but.. such differences may be due to language differences.
If you read this message than you can send replay for it and move to another folder one by one - case close
I'll show you my solution for one of that case around invoices on my site.
I create (if doesn't) and move message to folder for any recipient. The are redy to read.
Take look on my solution: przeniesienie-do-podfolderow and one of subject can include invoice.
or another solution like save attachments anyway (I set destination for each cases), where I found Invice in filename: automatyczny-zapis-zalacznikow
or you can write procedure in Outlook developer editor to look read messages in Input folder with invoice in Subject and move it to specific folder, by your self.
