Scheduling Delayed Delivery of Emails in Outlook

Microsoft Outlook supports the scheduling of email messages to send at a later date and time instead of sending them immediately.

Create a Send Delay for All Emails

You can create an email message template that automatically includes a send delay for all messages you create and send. This is handy if you often make a change to an email you just sent, or you’ve sent an email that you regretted sending hastily. By adding a default delay to all your emails, you prevent them from being sent immediately. This gives you an opportunity to make changes or cancel them if it’s within the delay you create. To create an email template with a send delay:

What Happens If Outlook Is Not Running at the Delivery Time?

If Outlook is not open and running at the time a message reaches its scheduled delivery time, the message is not delivered. The next time you launch Outlook, the message is sent immediately.

What Happens If There Is No Internet Connection at the Delivery Time?

If you are not connected to the internet at the time of scheduled delivery and Outlook is open, Outlook attempts to deliver the email at the specified time, but it will fail. You will see an Outlook Send/Receive Progress error window. Outlook also automatically attempts to send again, though, at a later time. When the connection is restored, Outlook sends the message. If Outlook is set to work in offline mode at the scheduled time of delivery, Outlook automatically sends as soon as the account used for the message is working online again.
