You know that moment when you finish writing an email at 11 PM and think — should I actually send this right now?

Maybe it's a follow-up to a client. Maybe it's a Monday morning reminder for your team. Either way, firing it off at midnight feels a little... much. Like showing up to a party two hours early.

That's exactly what email scheduling is for. And if you use Microsoft Outlook, you've had this feature sitting right there the whole time — you just might not have known where to look.

Here's how to use it across every version of Outlook.

Why Bother Scheduling Emails at All?

Honestly, it's more useful than it sounds at first.

Beyond the "I don't want to look like I have no life" reason, scheduling emails helps you reach people when they're actually paying attention. Sending something at 7 AM Tuesday hits differently than sending it Sunday night. And if you work with people in different time zones, it's basically essential.

There's also the "future you will forget" problem. You think of something important at 9 PM, draft it while it's fresh, and schedule it to land in someone's inbox at a normal human hour. Problem solved.

Alright — let's get into it.

How to Schedule an Email in Outlook on Windows (Classic Desktop App)

This is probably the version most people use at work, so let's start here.

  1. Open Outlook and compose your email like normal
  2. Before you hit Send, click the Options tab at the top
  3. Select Delay Delivery
  4. Check the box that says "Do not deliver before"
  5. Set your date and time
  6. Click Close, then hit Send

The email won't go anywhere immediately — it'll sit in your Outbox until the time you set. Then it sends automatically.

One important thing: the classic Outlook desktop app needs to be open and connected to the internet at the time of sending. If your laptop is off or you're not connected, the email just waits. Keep that in mind if you're scheduling something critical.

Using the New Outlook for Windows?

Microsoft has been rolling out a redesigned version of Outlook — and honestly, scheduling is way easier in it.

Just compose your email, then click the small dropdown arrow next to the Send button. You'll see a Schedule Send option. Pick one of the suggested times or set a custom one. Done. Much more intuitive.

How to Schedule Emails in Outlook on Mac

Same idea, slightly different steps.

  1. Compose your email
  2. Look for the small dropdown arrow right next to the Send button
  3. Click Send Later
  4. Pick your date and time

The Mac version handles this more gracefully than old Windows Outlook — especially if you're on a Microsoft 365 account. It processes the scheduling server-side, so you don't need to keep the app open. Write it, schedule it, close your laptop. It'll send.

How to Schedule Emails in Outlook on the Web

If you use Outlook through a browser — either at outlook.live.com or through your company's setup — this works entirely in the cloud.

  1. Compose your email
  2. Click the dropdown arrow next to Send
  3. Choose Send later
  4. Set your time and confirm

No app needed, no computer needs to stay on. It all happens on Microsoft's servers. This is probably the most reliable method if you're scheduling something and won't be at your desk.

Scheduling Emails on the Outlook Mobile App

This works on both iPhone and Android, and it's surprisingly easy.

  1. Write your email in the app
  2. Tap the three-dot menu in the top-right corner
  3. Select Schedule Send
  4. Choose a time or enter a custom one
  5. Tap Schedule

Really useful when an idea hits you on the go and you want to capture it without blasting someone's phone at 6 AM.

A Few Things to Know Before You Schedule

Editing or canceling a scheduled email: Go to your Outbox, open the message and make your changes — or delete it entirely if you change your mind. It's not locked in.

Time zones: Outlook uses your device's local time. If you're scheduling for someone in a different time zone, do the math manually. There's no automatic conversion.

Classic desktop app reminder: Say it again for the people in the back — if you're on old Outlook for Windows, your computer needs to be on and connected when the send time hits. Set a phone reminder if it's something important.

That's really all there is to it. Four versions of Outlook, four slightly different paths — but they all get you to the same place.

Pick your method, schedule something tonight, and enjoy the quiet satisfaction of knowing tomorrow-morning-you already has it handled.
