Hi Sloane
Greetings
Thank you for choosing Microsoft Community.
Checked the Outlook tracking options and unfortunately, the only options are the delivery receipt and the read receipt.
However after doing some research I found an add in, that lets you track activity on emails you have sent, which helps you automatically remind you when you don’t hear back from an email you sent. The add-in is called Boomerang, which can be used in your Outlook.
Please try it out and feel free to let me know how it goes .
Kind Regards,
Momo
