A read receipt is a receipt generated when your email has been opened by the recipient. For as long as your email remains unread or unopened in their inbox, this receipt isn’t generated.

Keep in mind that not all the email providers and applications support read receipts in Outlook. For those who don’t support it, you will not receive any receipts for your emails in Outlook.
