Email Extraction Macro

This project is to accomplish an extraction task on outlook inboxes. The files are ost format. Below is the scope. - Search a particular folder in outlook - Search for emails with a specific subject line and extract the senders & recipient emails from each email. - The extracted data needs to go into an excel sheet. This script/program needs to handle 10K+ emails and not freeze. Not sure how this would be accomplished but this is the scope. I can not provide a sample ost file as this is a confidential project.
