How Do I Delay An Email In Outlook

Delaying an email in Outlook gives you a crucial window to catch mistakes before they reach your recipient. If you have ever wondered “how do i delay an email in outlook,” you are not alone—this simple feature can save you from embarrassing typos, wrong attachments, or sending to the wrong person.

In this guide, I will show you step-by-step methods to delay your emails in Outlook, whether you use the desktop app, web version, or mobile. You will learn rules, settings, and pro tips to make your email sending safer and more controlled.

Why Delay An Email In Outlook

Emails are permanent. Once you hit send, you cannot take it back (unless you use recall, which is unreliable). A delay gives you a few minutes to review your message before it leaves your outbox.

Common reasons to delay include:

Catching spelling and grammar mistakes
Verifying you attached the right file
Checking the recipient list is correct
Preventing late-night email regrets
Giving yourself time to cool down before replying angrily

A delay is not the same as scheduling an email. Scheduling sets a specific send time. Delaying holds every email for a set period, like 1 or 5 minutes, before sending automatically.

This section answers the exact question: “how do i delay an email in outlook.” The method depends on which version of Outlook you use. Below are the most common approaches.

Using Outlook Desktop (Windows)

The desktop version offers the most control. You can create a rule that delays all outgoing messages or set a delay for individual emails.

Create A Rule To Delay All Emails

This method applies a delay to every email you send. Follow these steps:

Open Outlook on your Windows computer.
Go to the File tab in the top-left corner.
Click Manage Rules & Alerts.
In the Rules and Alerts window, click New Rule.
Under “Start from a blank rule,” select Apply rule on messages I send and click Next.
You will see a list of conditions. Do not select any—just click Next.
A pop-up will ask if you want the rule to apply to all messages. Click Yes.
Now, under “Select action(s),” check defer delivery by a number of minutes.
At the bottom, click the underlined phrase a number of minutes.
Set your delay time (e.g., 2 minutes) and click OK.
Click Next twice, then name your rule (e.g., “Delay All Emails”).
Check Turn on this rule and click Finish.

Now, every email you send will sit in your Outbox for the time you set. You can still open and edit it during that window.

Delay A Single Email Manually

If you only want to delay one email, use the Delivery Options:

Compose a new email as usual.
Click the Options tab in the email window.
In the “More Options” group, click Delay Delivery.
A dialog box opens. Under “Delivery options,” check Do not deliver before.
Set a date and time in the future.
Click Close, then send the email normally.
The email stays in your Outbox until the specified time.

This method is great for one-off delays without affecting your other emails.

Using Outlook On The Web (OWA)

The web version does not have a built-in “delay delivery” rule like the desktop app. However, you can use the “Undo Send” feature as a workaround.

Enable And Use Undo Send

This feature gives you a short window to cancel sending after you click Send.

Log into Outlook on the web (outlook.com or your work portal).
Click the Settings gear icon in the top-right corner.
Select View all Outlook settings at the bottom.
Go to Mail > Compose and reply.
Under “Undo send,” set the delay time. Options are 5, 10, 15, or 30 seconds.
Click Save.

Now, after you send an email, a banner appears at the top saying “Sending…” with an Undo button. Clicking it stops the email from being sent. You can then edit or delete it.

Note: This is not a true delay. It only works for the seconds you set. For longer delays, you must use the desktop app or schedule the email.

Using Outlook For Mac

Mac users have a similar rule system to Windows. Here is how to delay emails on a Mac:

Open Outlook for Mac.
Go to Tools > Rules.
Click the + icon to create a new rule.
Name your rule (e.g., “Delay Outgoing”).
Under “When a new message arrives,” select Outgoing messages.
Under “Do the following,” choose Defer delivery by.
Enter the number of minutes (e.g., 2).
Click OK to save the rule.

This rule delays all outgoing emails. You can also set individual delays using the “Delay Delivery” option in the email’s Options menu.

Using Outlook Mobile App

The mobile app does not support delay rules. However, you can use the “Undo Send” feature if your account is set up with Exchange or Microsoft 365.

Open the Outlook app on your phone.
Tap your profile picture or the Settings gear.
Select the account you want to adjust.
Scroll to Undo Send and choose a time (up to 10 seconds).
Save changes.

After sending, you have a few seconds to tap Undo. This is the only delay option on mobile.

Best Practices For Email Delays

Setting a delay is easy, but using it wisely makes a difference. Here are some tips to get the most out of this feature.

Choose The Right Delay Duration

Too short, and you might miss a mistake. Too long, and your recipient waits unnecessarily. Common choices:

1 minute: Good for quick proofreads.
2-3 minutes: Standard for most users.
5 minutes: Best for important or emotional emails.

Test different durations to see what works for you. Remember, you can always edit or delete the email while it sits in the Outbox.

Combine With Other Safety Features

Delaying alone is not foolproof. Use these additional features:

Delivery Receipts: Confirm when your email is opened.
Recall: Attempt to replace a sent email (works only within the same organization).
Read Receipts: Get notified when someone reads your email.

However, recall is unreliable. Delaying is much more effective for preventing mistakes.

Check Your Outbox Regularly

Delayed emails sit in your Outbox. If you close Outlook before the delay ends, the email might not send until you reopen the app. Make sure Outlook stays open until the email is sent.

Also, if you use a shared computer, log out properly to prevent others from seeing your delayed emails.

Troubleshooting Common Issues

Sometimes delays do not work as expected. Here are fixes for common problems.

Email Not Delayed Even After Setting Rule

Check that the rule is enabled. Go to File > Manage Rules & Alerts and make sure the rule has a checkmark next to it. Also, ensure you selected “Apply rule on messages I send” and not “Apply rule on messages I receive.”

Delay Only Works Sometimes

This can happen if you have multiple rules conflicting. Disable other rules temporarily to test. Also, if you use “Do not deliver before” on a single email, it overrides the global rule for that email.

Outlook Crashes Before Email Sends

If Outlook crashes, the delayed email may be lost. To avoid this, save important emails as drafts before setting a delay. You can also set a shorter delay (like 1 minute) to reduce the risk.

Undo Send Not Showing In Web Version

Make sure you are using the modern version of Outlook on the web. The classic version does not support Undo Send. Switch to the new interface by clicking “Try the new Outlook” in the top-right corner.

Alternatives To Delaying Emails

If delaying does not fit your workflow, consider these alternatives.

Schedule Emails For Later

Scheduling lets you choose a specific send time. This is useful for sending emails during business hours or on a specific date.

In Outlook Desktop:

Compose your email.
Click Options > Delay Delivery.
Set the “Do not deliver before” date and time.
Send normally.

In Outlook Web:

Compose your email.
Click the dropdown arrow next to Send.
Select Schedule send.
Choose a time or pick a custom one.

Use Third-Party Tools

Some add-ins offer advanced delay features. Examples include:

Boomerang: Schedule emails, set reminders, and delay sending.
Send Later: A simple tool for scheduling.
Microsoft Power Automate: Create custom workflows for email delays.

These tools often integrate with Outlook and provide more flexibility than built-in options.

Frequently Asked Questions

Can I Delay An Email In Outlook After I Have Sent It?

No, once you click Send, you cannot add a delay. However, if you use Undo Send (web or mobile), you have a few seconds to cancel the send. After that, the email is gone.

Does Delaying An Email Work If I Am Offline?

Yes. Delayed emails stay in your Outbox until you connect to the internet. When you go online, Outlook sends them according to the delay rule.

How Do I Delay An Email In Outlook For A Specific Recipient Only?

Create a rule with a condition like “with specific words in the recipient’s address.” Then set the delay action. This way, only emails to that person are delayed.

What Is The Maximum Delay Time I Can Set?

In the desktop rule, you can set up to 120 minutes (2 hours). For individual emails using “Do not deliver before,” you can set any future date and time.

Will Delaying An Email Affect My Sent Items Folder?

No. The email only moves to your Sent Items folder after it is actually sent. While delayed, it stays in your Outbox.
