Have you worked for an hour on the perfect e-mail for a client or co-worker just to find out they never received it? Or know you've sent an e-mail, but someone claims they didn't get. Outlook provides Read Receipts as a tool to track sent messages. You can turn on Read Receipts for all your e-mails or for certain important messages. When the person receives the e-mail message and views it, Outlook prompts him to send a Read Receipt.
Open Outlook by clicking on your desktop icon. Open the "Tools" menu and click "Options." Click "E-mail Options" in the "Preferences" tab.
Click the "Tracking Options" button in the "Message Handling" section. Click the "Read Receipt" or "Delivery Receipt" option under "For all messages I send, request." A "Delivery Receipt" automatically returns a message to you that delivery occurred. Whereas the user must agree to reply to a "Read Receipt."
Click "OK" to apply the changes and close the window. To send these requests with for a single email, click the "Options" button in the compose window. Click the check box for "Read Receipt" or "Delivery Receipt."
