One of my facvorite features in Outlook (for PC) is the Delay Delivery option. You can schedule an email to go out at a future date and time, and if you leave Outlook open, it will automatically send at that time.
Sometimes I’ll have a good idea over the weekend or in the evening, but I don’t want to bother my customer or colleague during his or her “down-time” with an email that is not time sensitive. Sometimes I want to allow more time before sending a follow-up to a previous message, but I don’t want to forget to follow up. I’ll set the Delay Delivery option knowing I can always delete the email or move it to the drafts folder if I decide not to send it.
Until the time the email is scheduled to go out, it will sit in your Outbox. No matter how many times you manually click “Send and Receive”, it won’t send until on or after the time you have scheduled it for.
If Outlook is closed at the scheduled send time, then the message will be sent the next time you open Outlook.
Note that when you close Outlook, you’ll receive a pop-up reminding you that “you have messages in your Outbox waiting to be sent”:
This is normal.
Instructions vary only slightly for each version of Outlook. Here’s how to schedule sending on an email in Office 2013:
