Outlook Schedule Send & Delay Delivery in 2026: Send Emails at the Perfect Time Every Time

Published: June 6, 2026 | Category: Outlook | Reading Time: 5 min

You finish writing an important email at 11 PM. You do not want to send it now—it might seem intrusive, or your recipient is in a different time zone—but you also do not want to forget about it in the morning. The solution is Outlook's Schedule Send and Delay Delivery features, which let you write emails whenever inspiration strikes and deliver them at exactly the right moment. In 2026, Outlook has made these tools smarter and more accessible than ever, with Copilot now suggesting optimal send times based on recipient behaviour. This guide covers every method available.

Method 1: Schedule Send (New Outlook for Windows and Web)

The new Outlook (the modern version introduced in 2023 and now the default for Microsoft 365 subscribers) has a built-in Schedule Send option directly on the compose window.

How to Schedule an Email to Send Later

Compose your email as normal.

Click the small dropdown arrow next to the Send button.

Select Schedule Send.

Choose from the suggested times (Outlook may suggest tomorrow morning, after business hours, etc.) or click Custom Time to pick a specific date and time.

Click Send. The email moves to your Drafts folder with a scheduled send indicator, not to the Sent Items yet.

The email sends automatically at the scheduled time as long as your Outlook is connected to the server (no need to have Outlook open—it sends via the Exchange server in the cloud).

How to Edit or Cancel a Scheduled Email

Go to your Drafts folder.

Find the email marked with a clock icon (scheduled).

Open the email and click Edit.

Make any changes, then reschedule or click Send Now to send immediately.

Method 2: Delay Delivery (Classic Outlook / Outlook Desktop)

In the classic Outlook desktop client, the equivalent feature is called Delay Delivery and is found in the message options. This method works even if your organisation has not yet migrated to the new Outlook experience.

Setting Delay Delivery on a Single Email

Compose your email.

In the compose window, go to the Options tab on the Ribbon.

Click the small arrow at the bottom-right of the More Options group to open Message Options.

Check the box next to Do not deliver before.

Set the date and time.

Close the dialog and click Send.

Important: In classic Outlook with an on-premises Exchange account, the email sits in your Outbox until the scheduled time. Outlook must remain open and connected for the email to send. With Microsoft 365 Exchange Online (the cloud version), the server handles delivery even if Outlook is closed.

Method 3: Delay All Outgoing Mail by a Few Minutes

A separate but related feature is a blanket delay on all outgoing email—for example, holding every email for two minutes before sending. This gives you a window to recall a message you immediately regret.

To set this up in classic Outlook:

Go to File > Manage Rules & Alerts > New Rule.

Choose Apply rule on messages I send.

Click Next until you reach the action step.

Check defer delivery by a number of minutes.

Click the link in the description to set the number of minutes (1–120).

Complete the rule wizard and click Finish.

With this rule active, every email you send sits in your Outbox for the specified delay before transmitting. To cancel a specific email within the window, simply open the Outbox and delete or edit it.

Copilot Suggested Send Times in 2026

One of the most useful Copilot features in the 2026 version of Outlook is smart send-time suggestions. When you schedule an email, Copilot analyses:

The recipient's typical working hours and time zone.

Historical patterns of when they open and respond to emails.

Their calendar availability (if they are in the same organisation).

Based on this analysis, Copilot suggests a specific time that maximises the likelihood of the email being read promptly. You see options like "Tomorrow at 9:15 AM (when Jana is typically most responsive)" rather than generic time slots. This is available for internal recipients within your Microsoft 365 organisation.

Practical Use Cases

Respecting work-life balance: Write your thoughts at 10 PM but deliver at 9 AM so recipients do not feel pressure to respond outside business hours.

Time zone management: Schedule emails to land during business hours for recipients in New York, London, or Singapore without doing the time zone arithmetic yourself.

Batch email campaigns: Prepare project status emails in advance and schedule them to send on Monday morning.

Meeting follow-ups: Write a follow-up immediately after a meeting while it is fresh and schedule it for after the attendees have had time to check their notes.

Holiday and OOO preparation: Prepare important emails before you go on leave and schedule them to deliver on specific dates while you are away.

Tips and Best Practices

Double-check the time zone: Outlook schedules sends in your local time zone. If you are travelling, confirm this matches your intended time.

Review scheduled emails regularly: Circumstances change. Get into the habit of scanning your Drafts folder for scheduled emails before major decisions or announcements.

Combine with Recall: Even after an email sends, Microsoft 365 Exchange allows you to attempt a recall (Message > Actions > Recall This Message) within a short window for recipients who have not yet opened it.

Conclusion

Schedule Send and Delay Delivery are among the most underused productivity features in Outlook, yet they make a genuine difference to professional communication quality and work-life boundaries. In 2026, with Copilot suggesting optimal send times based on recipient behaviour, there is really no reason to hit Send at the wrong moment ever again. Set up a blanket two-minute delay today as a safety net, and use Schedule Send for any email where timing matters.
