How to delay all emails in new Outlook

Checked against Microsoft's documentation on November 5, 2026. Published by Delay Send, which sells one of the options below.

Short answer: new Outlook has no rule that delays every email you send; only classic Outlook has one. Built in, you get Undo send (up to 30 seconds, every email) and Schedule send (any time, one email at a time). To hold every email for minutes, go back to classic Outlook or use an add-in.

Your options, side by side

Option	Every email?	Longest wait	Where the email waits	Cost
Undo send new Outlook, Outlook.com	Yes	30 seconds	You cancel it during the wait	Free
Schedule send new Outlook, web	No, you pick a time each time	Any time you choose	Drafts	Free
Rule in classic Outlook classic Outlook for Windows only	Yes	120 minutes	Outbox; Outlook must stay online and connected	Free
Delay Send add-in new Outlook, Mac, web	Yes	10 minutes	Drafts	$29 a year or $59 once

Is the rule really gone?

Yes. In January 2026 a Microsoft Q&A moderator answered this directly: the new Outlook for Windows "doesn't support a rule that delays or defers all outgoing messages in the same way Classic Outlook does", and Microsoft hasn't shared a timeline for adding it. People have been asking since 2023.

Microsoft's help page on delaying email also lists the rule under classic Outlook only.

Some articles describe a "delay delivery" rule in new Outlook with a 1 to 10 minute slider. We couldn't find that in any Microsoft documentation. If your Rules settings don't show it, you aren't missing a setting.

Option 1: Undo send

This is the closest thing built in, and it applies to everything you send. Microsoft says you can delay sending for up to 30 seconds.

Open Settings, then Mail, then Compose and reply.
Under Undo send, choose how many seconds to wait.
Save.

Thirty seconds is enough to catch a typo you spot right away. It isn't enough if you tend to notice the wrong attachment a minute later.

Option 2: Schedule send

Good when one particular email should go out later. Not a safety net, because you have to remember it each time.

While writing the email, open the dropdown next to Send and choose Schedule send.
Pick a default time or a custom one, then select Send.
The email stays in Drafts until then. To change it, open it in Drafts and select Cancel send.

Microsoft notes this doesn't work with IMAP or POP accounts.

Option 3: The rule in classic Outlook

If your organization still lets you use classic Outlook for Windows, this is the original feature, and it's free. Use the toggle at the top right of new Outlook to switch back, then:

Select File, then Manage Rules & Alerts, then New Rule.
Under Start from a Blank Rule, choose Apply rule on messages I send, then Next.
Leave the conditions empty and select Next. Confirm with Yes to apply it to every email.
Check defer delivery by a number of minutes, click a number of and enter the minutes (up to 120).
Select OK, then Next twice, name the rule, turn it on and select Finish.

Messages wait in the Outbox, and Microsoft says Outlook needs to be online and connected for this to work. So if you close Outlook during the wait, the email waits too.

Option 4: An add-in that delays every email

This is what we make. Delay Send is an add-in that uses Outlook's own delivery scheduling: when you press Send, it sets a delivery time 1, 2, 5 or 10 minutes ahead, the same mechanism Schedule send uses. You keep sending the way you always do.

Open the email in Drafts during the wait to fix the recipient, add the file or change a line.
It goes out on its own, because the mailbox holds the timer rather than your computer.
To send something right away, switch the delay off in the Delay Send pane.

What it doesn't do:

It doesn't delay email sent from the Outlook phone apps. Microsoft doesn't run this type of add-in on iOS or Android, so those emails leave immediately.
It doesn't work in classic Outlook for Windows. Use the rule above there.
Your organization may block add-ins on work accounts. Check with IT before you buy.
The longest wait is 10 minutes. If you need more, use Schedule send or the classic rule.

We tested it on October 29, 2026 with a hotmail.com mailbox in Outlook on the web and a 5 minute delay: Outlook showed the email as scheduled, and it arrived 5 minutes later.

Which one should you pick?

You only catch typos right after sending: Undo send, set to 30 seconds. It's free.
You sometimes want one email to go out tomorrow morning: Schedule send.
You use classic Outlook and can stay on it: the rule.
You're on new Outlook, Mac or the web and want minutes on every email: an add-in like Delay Send.

What about recalling a sent email?

Recall is not a substitute. Microsoft says it works only if you and the recipient both have Microsoft 365 work or school accounts in the same organization, and only for people who haven't opened the message. Personal accounts can't use it at all.
