In the Step 1: Navigate to 'Start from a Blank Rule' and choose a template box, then click 'Apply rule on messages I send'. Click on File and navigate to Manage Rules & Alerts > New Rule. You should also keep in mind that you can only delay the delivery of all the emails by up to two hours. In order to do this, you will need to create a rule for it. Outlook allows you to delay all emails' delivery with one option.

Now navigate to the Delivery options and find and clear the 'Do not deliver before' checkbox.

Under the Tags group in the Ribbon, click on the More options arrow icon.

Navigate to the Outbox folder and find and open the delayed email.

If you decide that you want to send the email immediately at a later time, then follow these instructions: Instead, it will remain in the Outbox folder until your specified date and time. Now when you click Send after composing your email, the email will not be sent immediately.

After configuring everything, click on Close.

Then specify the delivery time and date of the email when you wish to send the email. Under that section, find and check the 'Do not deliver before' checkbox. It is displayed under the Tag group in the Ribbon. While you are composing an email, click on the More options arrow icon.

This method is straightforward as you don't have to create any rule and you simply need to use the Delivery option to delay the sending according to your preferences. The method to delay a single email in Outlook is different as compared to delaying the delivery of all emails.
