What Is Email Recall in New Outlook?
Email recall allows you to:
-
Delete unread copies of a sent message
-
Replace the message with a corrected version
However, this feature only works under specific conditions—mainly within Microsoft 365 or Exchange accounts inside the same organization.
If recall is not supported, Outlook offers alternatives like:
-
Undo Send
-
Delayed sending
-
Sending correction emails
Important Things to Know Before Recalling an Email
Before attempting recall, understand these critical limitations:
✔ Both sender and recipient must use Microsoft 365 or Exchange
✔ It works best within the same organization/company
✔ The recipient must NOT have opened the email
✔ The email must still be in their inbox (not moved to folders)
✔ Recall does NOT work with Gmail, Yahoo, or other providers
✔ Recall is not available for POP/IMAP accounts
⚠️ If any of these conditions fail, recall will not succeed.
Method 1: Recall an Email in New Outlook (Desktop App)
This is the most reliable method.
It works in the New Outlook desktop app for Windows when using Microsoft 365 or Exchange accounts.
Step-by-Step Instructions
-
Open New Outlook on your PC
-
Go to Sent Items
-
Double-click the email you want to recall (it must open in a new window)
-
Click File
-
Select Info
-
Click Recall This Message
-
Choose one option:
-
🔹 Delete unread copies of this message
-
🔹 Delete unread copies and replace with a new message
-
-
Click OK
You’ll receive a notification telling you whether the recall succeeded or failed.
What Happens After Recall?
-
If successful → The email disappears from the recipient’s inbox.
-
If opened → Recall fails.
-
If replaced → Recipient receives the new version.
Pros
✔ Can completely remove unread emails
✔ Allows replacing incorrect messages
✔ Works automatically within organizations
Cons
✖ Only works for Exchange/Microsoft 365
✖ Fails if recipient already opened email
✖ Doesn’t work for external email providers
Method 2: Use Undo Send in Outlook Online (Web Version)
Outlook Web does not provide traditional recall, but it offers something even better for quick mistakes: Undo Send.
Undo Send delays sending your message for a few seconds, allowing you to cancel it before it leaves your outbox.
How to Enable Undo Send in Outlook Web
-
Open Outlook Web
-
Click the Settings (⚙️ icon)
-
Go to Mail → Compose and Reply
-
Scroll to Undo Send
-
Set delay time (up to 10 seconds)
-
Click Save
How to Use Undo Send
-
Send an email
-
A small pop-up appears at the bottom
-
Click Undo within the delay time
Once the delay passes, the email is permanently sent.
Pros
✔ Works instantly
✔ Prevents email from being delivered
✔ Works for personal Outlook accounts
Cons
✖ Maximum 10-second delay
✖ Cannot recall after delivery
Method 3: Recall an Email in Browser-Based New Outlook
If you’re using the New Outlook interface inside a browser and have an Exchange account, you may see a recall option.
Steps
-
Open Outlook in your browser
-
Go to Sent Items
-
Open the sent email
-
Click the three dots (More options)
-
If available, select Recall this message
-
Confirm your choice
⚠️ This option appears only for eligible Microsoft 365 accounts.
Method 4: Recall Email in Outlook Mobile (Android & iOS)
Unfortunately, the Outlook mobile app does NOT support email recall.
Alternatives for Mobile Users
-
Enable Undo Send (if available)
-
Immediately send a correction email
-
Contact recipient directly if urgent
Currently, Microsoft has not added recall functionality to mobile apps.
Why Email Recall Sometimes Doesn’t Work
Even when following steps correctly, recall may fail due to:
-
Recipient already opened the email
-
Recipient uses Gmail or another provider
-
Email was sent outside your organization
-
Email moved to another folder
-
Public/shared mailbox involvement
-
Cached Exchange mode conflicts
If recall fails, Outlook will notify you.
What To Do If Email Recall Fails
Don’t panic. Here’s what you can do:
1️⃣ Send a Professional Follow-Up
Example format:
-
Acknowledge the mistake
-
Provide corrected information
-
Keep it short
Example:
“Please disregard my previous email. The correct attachment is included below.”
2️⃣ Use Delay Delivery for Future Emails
To prevent mistakes:
-
Go to File → Manage Rules & Alerts
-
Create a rule to delay sending by 1–2 minutes
-
Apply to all outgoing messages
This gives you a safety buffer.
3️⃣ Schedule Emails Instead of Sending Immediately
Instead of clicking Send:
-
Use Schedule Send
-
Set delivery time 5–10 minutes later
-
Cancel if needed
Pro Tips to Avoid Email Mistakes
✔ Double-check recipients before sending
✔ Always verify attachments
✔ Re-read subject lines
✔ Avoid sending emails when stressed
✔ Enable Undo Send on all devices
