If you use the desktop version of Outlook with your Microsoft 365 subscription, or virtually any other version of Office, including Office 2019 and Office 2016, you can schedule an email to send it at later time.
Although you usually compose and send an email immediately, sometimes having the ability to send an email later can come in handy. For instance, when you must email someone at a specific time, or if you have to email a person, but you’re now confident about the message, and you want a way to change your mind.
Whatever the reason it might be, the desktop version of Outlook lets you change the delivery settings to send emails at specific time.
How to send email on schedule using Outlook desktop app
To use Outlook to schedule an email, use these steps:
Open Outlook app.
Click the New Email button from the “Home” tab.
Compose your message.
Click the Options tab.
Under the “More options” section, click the Delay Delivery button.
Under the “Delivery options” section, check the Do not deliver before option.
Choose the date and time to schedule and send the email.
Click the Close button.
Click the Send button.
Once you complete the steps, the message will stay in the Outbox section until the schedule you specified, and then it’ll send it automatically.
