OfficeTalk lets you send a delayed mail message. This is sometimes useful if you wish to remind yourself or a colleague to do something in the future by sending them a mail message. You can send a delayed message 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 Delayed Send check box and specify a date and time when the message should be sent. Press the Send button.
The message will not arrive at the recipients until after the date and time specified.
Note: Delaying the sending of a message only works for messages sent to local OfficeTalk users. Delayed messages sent to other recipients are sent immediately.
