Sometimes when you send a mail message to someone, you would like to know when they received the message. You can instruct OfficeTalk to send you a confirmation message when the recipient of your message has opened the message. You can do this in the following way:
Compose the message in the normal way and then press the 
button. The Send Mail dialog box is displayed. Select the Advanced page.
Check the Require Read Confirmation check box. Press the Send button. When the message is opened, you will be sent back a confirmation message informing you that the message has been read.
Note: Read Confirmation only works for messages sent to local or remote OfficeTalk users. Messages sent to other recipients will not return a read confirmation message.
