Scheduling an email in Outlook is one of those features most people discover years after they needed it. The ability to write an email now but deliver it at a specific time later is useful in more situations than just early-morning sends: it lets you write while something is fresh without interrupting someone's evening, coordinate sends across time zones, and batch email work to a single session without bombarding recipients the moment you write each message. Paired with good workplace habits around communication, scheduled email is one of the simplest productivity improvements you can make without changing anything about how you work.

Outlook offers scheduled send across three versions of the app: Classic Outlook (the legacy desktop client), New Outlook (the redesigned version rolling out to Microsoft 365 users), and Outlook on the Web. The steps differ slightly across each. This guide walks through all three, plus how to manage or cancel a scheduled email and what to do when it doesn't work.

Key Takeaways

• Classic Outlook schedules delivery through the Delay Delivery option in the message's Options tab. The email sits in your Outbox until the scheduled time and requires Outlook to be running.

• New Outlook and Outlook Web use a "Schedule send" button in the send dropdown, and delivery is handled by Microsoft's servers so Outlook doesn't need to stay open.

• You can reschedule or cancel a scheduled email by opening it from your Outbox (Classic) or Drafts/Scheduled folder (New Outlook and Web) before the send time arrives.

How to Schedule an Email in Classic Outlook

Classic Outlook (also called Outlook Desktop or Outlook Legacy) handles scheduling through the Delay Delivery feature in the message composition window. Here's how:

1. Open Outlook and compose your email as normal.

2. In the message window, click the Options tab in the ribbon at the top.

3. In the "More Options" group, click Delay Delivery. A dialog box opens.

4. Under "Delivery options," check the box next to Do not deliver before.

5. Set your desired date and time in the fields that appear.

6. Click Close to dismiss the dialog, then click Send as normal.

The email will move to your Outbox and sit there until the scheduled time. Important: In Classic Outlook, the email sends only if Outlook is open and connected at the delivery time. If your computer is off or Outlook is closed, the email will send the next time Outlook connects to the mail server and the scheduled time has passed.

How to Schedule an Email in New Outlook

New Outlook (the updated version of the app for Microsoft 365 users) has a more intuitive scheduled send feature that works even when Outlook is closed:

1. Open New Outlook and compose your email.

2. Instead of clicking the Send button directly, click the dropdown arrow (small chevron or caret) next to the Send button.

3. Select Schedule send from the dropdown menu.

4. A panel or dialog appears with suggested send times. You can select one of the suggestions or click Custom time to pick a specific date and time.

5. Click Send (or the equivalent confirmation button) to schedule.

The email will appear in your Scheduled folder (found in the left sidebar under Drafts in some configurations) until the delivery time. Because New Outlook routes scheduling through Microsoft's servers, your computer doesn't need to be on for the email to send at the right time.

How to Schedule an Email in Outlook Web

Outlook Web (accessed through outlook.live.com or your organization's webmail portal) has the same server-side scheduling as New Outlook:

1. Go to outlook.live.com or your organization's Outlook web address and sign in.

2. Compose a new email using the New message button.

3. Write your email, then look for the dropdown arrow next to the Send button at the bottom of the compose window.

4. Click the arrow and select Send later or Schedule send.

5. In the dialog that appears, select a suggested time or use the date and time picker to enter a custom time.

6. Click Send to confirm.

The scheduled email will appear in your Drafts folder with a scheduled badge, or in a dedicated Scheduled folder depending on your Outlook version. As with New Outlook, no connection is needed at send time since Microsoft handles delivery on their servers.

How to Manage or Cancel a Scheduled Email

In Classic Outlook

Go to your Outbox folder. The scheduled email will be there. Double-click to open it. Go to Options > Delay Delivery and uncheck "Do not deliver before" to send immediately, or change the date and time to reschedule. Click Close and then Send again to save the change.

If you want to cancel entirely without sending: open the email from Outbox, click Delete or move it to Drafts before the send time.

In New Outlook and Outlook Web

Find the email in your Scheduled or Drafts folder. Open it. You'll see options to edit, reschedule, or cancel. Clicking cancel will return the email to your Drafts as an unsent message. Clicking edit lets you change the content or pick a new send time.

Common Issues and Troubleshooting

The email sent immediately instead of at the scheduled time (Classic Outlook)

This happens when you've already configured a send/receive to run right after composing, or if Outlook is set to send immediately on connection. In Classic Outlook, go to File > Options > Advanced > Send and Receive and make sure your settings are aligned with how you want delivery to work. Also confirm that the "Do not deliver before" checkbox was checked and saved correctly before clicking Send.

The email is stuck in Outbox and won't send (Classic Outlook)

Two possibilities: either Outlook isn't connected to the mail server at the scheduled time, or the email is too large and fails silently. Check your send/receive settings and verify your connection. For large attachments, consider using OneDrive links instead of direct attachments.

I can't find the Scheduled folder (New Outlook)

In some configurations of New Outlook, scheduled emails appear in Drafts with a clock icon rather than a separate Scheduled folder. Check your Drafts folder and look for emails with a scheduling indicator. If you recently switched from Classic to New Outlook, the folder structure may differ from what you expect.

The schedule send option doesn't appear

In New Outlook and Outlook Web, the schedule send option appears only in the dropdown next to the Send button, not as a standalone button. Make sure you're clicking the small arrow or chevron icon next to Send, not Send itself. If the option still doesn't appear, your administrator may have restricted the feature or your Outlook version may need an update.

Best Practices for Scheduling Emails

Match your sends to the recipient's working hours

Scheduling for 9am in the recipient's time zone is more considerate than sending at 11pm your time. It also aligns with what research on optimal scheduling and deep work shows: people are most receptive and responsive during their natural morning peak. Most people are more likely to read and respond to emails that arrive at the start of their day, when their inbox is fresh rather than already crowded.

Batch your email writing to one or two sessions per day

Scheduled send makes it practical to write all your emails in a dedicated morning or afternoon block and have them deliver throughout the day at appropriate times. This approach keeps you out of reactive email mode. For broader strategies, our guide on focusing at work covers how to protect deep work sessions from communication interruptions. and have them deliver throughout the day at appropriate times. This approach keeps you out of reactive email mode and lets you use your best focus time for deeper work. Using Outlook Focus Time alongside scheduled email lets you protect blocks for deep work while still maintaining timely communication.

Review before the send time arrives

Scheduled emails are still editable until they go out. Building in a brief review window before the send time is a safety net against sending a message written in frustration or before you've confirmed a detail. Even a one-hour gap between writing and sending has prevented more than a few regrettable emails.

Pair email scheduling with calendar blocking

Email management and calendar management work better together. The best Outlook scheduling assistant apps and tools that pair with Outlook Calendar can help you schedule communication time the same way you schedule meetings, so email doesn't bleed into focused work sessions. Lifestack syncs with Outlook Calendar and builds your daily schedule around your energy peaks, which pairs naturally with batching email to your lower-energy windows and protecting your peak focus time for work that actually requires it.

FAQ

Does Outlook need to be open for a scheduled email to send?

In Classic Outlook: yes. The email sits in your Outbox and sends the next time Outlook is open and connected to the mail server after the scheduled time. In New Outlook and Outlook Web: no. Microsoft's servers handle delivery, so your computer can be off and the email will still send on schedule.

Can you schedule an email in Outlook on mobile?

Outlook mobile (iOS and Android) added scheduled send support in 2024. In the Outlook mobile app, compose your email and look for the schedule icon (clock or send later option) in the compose toolbar or send button dropdown. The experience varies slightly between platforms.

Can you schedule a recurring email in Outlook?

Outlook doesn't have a native recurring email feature for sending the same email repeatedly on a schedule. For recurring communication, you can use a mail merge combined with a scheduled send, use an Outlook add-in that adds recurring email functionality, or set a recurring reminder to compose and schedule the email manually each time.

How far in advance can you schedule an email in Outlook?

There's no documented limit for how far in advance you can schedule an email in Outlook. In practice, emails scheduled months or years in advance work in both Classic and New Outlook. The practical limit is the accuracy of your future plans rather than any technical constraint.

What happens to a scheduled email if the recipient's email bounces?

A scheduled email that bounces after delivery will generate a non-delivery report (NDR) in your inbox, the same as a normally sent email. The scheduling mechanism doesn't affect how bounces are handled. You'll receive the bounce notification after the scheduled send time.

Is there a way to schedule emails in Outlook for Mac?

Yes. Outlook for Mac supports scheduled send. In the compose window, click the dropdown arrow next to the Send button and select "Send Later" or "Schedule Send." Set your date and time and confirm. The Mac version uses Microsoft's servers for delivery in the same way as New Outlook on Windows, so Outlook doesn't need to stay open.
