Retrieving Email Data from Mailbox for the Past 6 Years

Quick tip: After exporting your email data, consider validating the addresses. Over 6 years, many emails become inactive or invalid. Using unvalidated lists can affect deliverability and sender reputation.

I recommend using an email validation tool like BillionVerify to verify your extracted email list and ensure data quality before using it.

 After running the above command, you can then export the results from SentItemsSearch folder into a CSV file using another command or manually download them.
