Classic Outlook Resend Message in New Outlook: What Changed

If you relied on the Resend Message feature in classic Outlook to forward a copy of a sent email with the original headers intact, you may have noticed it is missing or behaves differently in the new Outlook for Windows. The new Outlook for Windows replaces the legacy MAPI-based architecture with a web-based platform, which removed several features including the traditional Resend and Recall commands. This article explains exactly what changed with the Resend Message feature, how the new Outlook handles resending messages, and which workarounds you can use to achieve a similar result.

Why the Resend Message Feature Was Removed in New Outlook

The Resend Message feature in classic Outlook allowed you to reopen any sent email, modify it, and send it again while retaining the original sender, recipients, subject, and headers. This was useful for correcting a mistake, re-sending a failed message, or forwarding a complete copy of a conversation without stripping metadata.

New Outlook for Windows is built on Microsoft’s web technology stack, the same platform used in Outlook on the web and the Outlook mobile app. This architecture does not support the low-level MAPI commands that enabled Resend and Recall. Microsoft decided to focus on the most commonly used features during the transition and left out those with low usage data. According to Microsoft’s official documentation, Resend and Recall are not planned for the initial release of new Outlook, though Recall may arrive later for organizations with specific Microsoft 365 licensing.

What Resend Actually Did in Classic Outlook

When you selected Resend in classic Outlook, it created a new copy of the original message with the same Internet Message ID and headers. The recipient saw the email as a resend, not a forward. The original sent date and time were preserved unless you manually changed them. This was different from Forward, which creates a new message with your address as the sender and strips the original headers.

How the New Outlook Handles Sent Items

In new Outlook, the right-click context menu on a sent email offers only Forward, Reply, Reply All, and Delete. There is no Resend option. The ribbon also lacks a Resend button. The new Outlook treats every sent email as a final version that cannot be re-sent with the original sender identity. This is a deliberate design choice to simplify the interface and align with the web client behavior.

How to Resend a Message in New Outlook: Step-by-Step Workarounds

Since the native Resend feature is gone, you have two main workarounds. Each has different results regarding headers and sender identity.

Method 1: Forward the Email as an Attachment

Forwarding as an attachment preserves the original message body, headers, and attachments inside a single .msg file. The recipient opens the attachment to see the original email exactly as sent. This is the closest match to the classic Resend behavior for preserving content.

1. Open the sent email in the reading pane or a separate window
   Double-click the email in your Sent Items folder to open it in its own window. This gives you access to more ribbon options.
2. Click the More actions button (three dots) in the toolbar
   In the opened email window, locate the ellipsis button in the top-right area of the ribbon. Click it to expand additional commands.
3. Select Forward as attachment from the menu
   A new compose window opens with the original email attached as an .msg file. The attachment name matches the subject line.
4. Address the new message and add any explanation text
   Type the recipient email addresses in the To field. You can add a brief note above the attachment explaining why you are resending.
5. Send the message
   Click Send. The recipient receives a new email from your address with the original message attached.

Method 2: Forward the Email and Manually Edit Headers

If you need the recipient to see the original sender and date without opening an attachment, you can forward the email and then manually paste the original headers into the body. This is more work but gives a cleaner reading experience.

1. Open the sent email and click Forward
   In the reading pane or the opened email window, click the Forward button. A new compose window opens with the original content.
2. Remove the auto-added Forwarded message prefix
   Delete the line that begins with “———- Forwarded message ———” from the top of the message body.
3. Copy the original headers from the sent email
   Open the original sent email again. Go to File > Info > Properties. In the Internet headers section, select all the header text and copy it.
4. Paste the headers at the top of the forwarded message body
   Place your cursor at the very beginning of the message body and paste the headers. This recreates the look of a resent message.
5. Send the message
   Address the recipient and click Send. The recipient sees the original headers and body in a single email from your address.

Common Issues and Limitations When Resending in New Outlook

Recipient Sees the Forwarder as Sender, Not the Original Sender

In new Outlook, any Forward action shows your email address as the sender. The original sender information is only visible inside the attachment or in the pasted headers. If your workflow requires the recipient to see the original sender in the From field, you must use classic Outlook or Outlook on the web with a third-party add-in.

Original Sent Date Is Not Preserved

When you forward an email, the new message receives the current date and time. The original sent date is lost unless you manually type it into the body or attachment. The Resend feature in classic Outlook preserved the original date.

Recall Is Also Missing

Recall, which allowed you to pull back a sent email from a recipient’s inbox, is not available in new Outlook. Microsoft has stated that Recall will be added later for users with Exchange Online and Microsoft 365 E3 or E5 licenses. Until then, the only way to recall a message is to use classic Outlook or Outlook on the web with the Recall button in the ribbon.

Resend for Meeting Updates and Task Requests

Classic Outlook allowed resending meeting updates and task requests as if they were emails. New Outlook handles these items differently. To resend a meeting update, open the meeting from your Calendar, click Edit, make any changes, and then click Send Update. For task requests, you must create a new task request manually.

Classic Outlook Resend vs New Outlook Workarounds: Comparison

Item	Classic Outlook Resend	New Outlook Workarounds
Sender identity	Original sender preserved	Your address appears as sender
Original headers	Kept intact	Only inside attachment or manually pasted
Original sent date	Preserved	Lost; current date used
Recipient experience	Sees a resent message with original metadata	Sees a new forward or an attachment to open
Recall support	Available	Not available
Meeting resend	Supported via Resend	Use Edit and Send Update

The classic Outlook Resend feature gave you full control over message identity and metadata. New Outlook replaces this with forwarding and manual header editing. If you need the original sender and date to appear in the recipient’s inbox, the only reliable method is to switch to classic Outlook temporarily or use the Forward as attachment workaround and instruct the recipient to open the .msg file.

To switch back to classic Outlook while Microsoft completes new Outlook, go to the toggle switch in the top-right corner of the new Outlook window and select the option to use classic Outlook. You can then use the Resend button from the ribbon or right-click menu. Microsoft has not announced a date for adding Resend to new Outlook, so the workarounds described here will remain relevant for the foreseeable future.

If you frequently resend emails for compliance or audit reasons, consider saving a copy of the original .msg file to your local drive before sending. This gives you a permanent record of the exact message you sent, including headers, regardless of which Outlook version you use.
