Did you know you can delay the delivery of email in Outlook? If you have a tendency to work late or very early by delaying your message the recipient won’t hear a ding in the small hours. If your recipient is out of the office, scheduling an important message to send when they return will put it at the top of their priority list. 

In Outlook, click the down arrow next to the Send button after you’ve finished writing your email. You can then click Send Later and select the time and day you’d like the email to be sent. You can view your scheduled emails in the Drafts folder.
