How do I disable delivery and/or read receipts?

Please note that you CANNOT disable delivery receipts as these are controlled by the server.

In Outlook 2016 you disable read receipts by doing the following:

1. Click on File in the top left hand corner
2. Select options on the left
3. From the Outlook Options window now select Mail on the left
4. 
5. Scroll down about 3/4's of the way on the right until you see the heading Tracking
6. 
7. If you want to DISABLE read receipts select NEVER send a read receipt
8. If you want to SEND a receipt without prompting you select Always send a read receipt
9. If you want to be prompt (recommended) select Ask each time whether to send a read receipt
10. Click on OK
