In some cases, you may want to delay sending a message in Outlook. normally, e-mail messages are sent immediately when you click the Send button in the Message window unless you aren’t connected to the internet (then it will sit in your Outbox until you connect).
You can delay sending the message by postponing the send date as follows:
In the Message window, Click the Options.
In the Message Options dialogue box, select Do Not Deliver Before check box, and choose the desired send date in the calendar drop-down and the desired time you want the message sent in the appropriate drop-down.
Click Close and Send.
Your message will go to the Outbox folder until the assigned date and time to send it.
