How can i set up a delay on all emails in New Outlook

I had the same question. I was able to establish a 10-second delay. (I have a Mac)

Pathway: Settings -> Mail -> Compose and reply -> Undo Send

We're not asking how to do this in Classic Outlook. That's the whole point, that this feature is not available in the new Outlook.

This is actually what we are looking for, though 10 seconds is not enough. The Classic Outlook rule only counts in minutes, and I have it personally set to 1. So the request should be to expand this timespan to (for my sake) 60 seconds.

Hi! I know how to put this setting in the new Outlook:

1. Click File
2. When this shows up, click Manage Rules and Alerts (it will not be in the blue side bar but in the middle under Account Settings)
3. Click "New Rule..."
4. Select "Apply rule on messages I send" and then click Next
5. Click next again (although if you want any of these specific things to apply, feel free to click any check boxes). If you do not check any boxes, a notification pop up will show asking if you want this rule to apply to every message you send. Click yes.
6. Select "defer delivery by a number of minutes". Once you select this check box, click "a number of minutes" in the box called "Step 2: Edit the rule description (click an underlined value)" below. Modify the number of minutes (this is up to you). Once you set this, click Next.
7. Click next again (although if you want any of these specific things to apply, feel free to click any check boxes.) The next step is naming the rule (up to you if you want to and what you want to name it).
8. Click Finish and you'll now have delayed email sending!

That's classic Outlook, not new Outlook
