In Outlook, copying an email creates a duplicate message that retains the original content, headers, and most attachments, while letting you edit the subject and recipients. This evergreen guide explains how to copy an email in the Outlook desktop app, Outlook on the web, and the Outlook mobile app, covering common methods, limitations, and practical use cases such as forwarding versus copying, safe handling of inline images, behavior with Outlook Data Files (PST/OST), and troubleshooting tips for missing features.
How the Built-in Copy Feature Works
Outlook provides several ways to duplicate a message. Which method works depends on the app (desktop, web, or mobile), your mailbox type (Exchange/M365, IMAP, POP), and whether you are working online or offline. Copying usually places the duplicate in the same folder; you must manually move or save it if you want it elsewhere. For audit, legal, or training scenarios, preserving original headers and timestamps is important; copying retains more metadata than a standard forward, but not every add-in or connector replicates exactly.
Desktop App (Windows and Mac)
On Windows and Mac, the recommended ways are Message Header Copy and Right-Click Duplicate. The Message Header Copy method is script-friendly and preserves structure, while the right-click method is convenient but behaves slightly differently depending on the view and store type (Exchange vs PST/OST). Certain items such as high-sensitivity messages or items governed by retention policies may limit duplication. If add-ins or custom forms intercept the copy action, behavior can vary; test with a non-sensitive message if your workflow depends on exact fidelity.
Outlook on the Web
Outlook on the web offers fewer native duplication options, so the common approach is to open the message and use Save as Draft or forward while preserving content and attachments. Headers are typically visible but less accessible than in the desktop app. In unified inboxes and focused inbox layouts, the experience can differ slightly; feature availability may change as the service updates. As with desktop, legal or compliance-sensitive workflows should verify archive behavior rather than rely solely on UI actions.
Outlook Mobile App
On iOS and Android, the app supports forwarding and saving drafts, but it does not expose a one-tap copy message command. Use the Forward flow and clear or adjust recipient fields to create a close equivalent, and verify that inline images and attachments carry over. The mobile client depends on server-side capabilities and may display different options depending on mailbox type and app version. For critical copies, prefer the desktop client when possible, and confirm the duplicated message includes all expected content.
Step-by-Step: Copy an Email in Outlook Desktop
Method 1: Message Header Copy
This method exposes the raw message header and body text, which you can paste into a new message. It is reliable across formats and useful for technical support or audits.
- Open the message you want to copy.
- Select File > Properties (or Message File Properties in some builds).
- In the Internet headers box, select the entire header text and copy it.
- Create a new email, paste the header into the body, and then paste the original message text below.
- Add a note that this is a copy if you plan to archive or share it.
Method 2: Right-Click Duplicate (Explorer Only)
Available in the main message list on Windows; not present in all views or on Mac.
- In the message list, select the conversation or single message.
- Press and hold Ctrl, then drag the message to the same folder.
- Release to create a copy with the same subject and visible content.
- Edit the subject as needed before sending.
Method 3: Save as Draft or Forward to Yourself
Use when you need a local copy inside Outlook or a safe place to edit. Saving as draft keeps the message in your account; forwarding is simpler but changes header layout and may alter perceived authorship.
- Open the message.
- Select Save & Close (Save as Draft) so it remains in Drafts, or choose Forward and remove/add recipients as appropriate.
- Move the resulting message to the desired folder.
What Gets Copied and What Does Not
Not every attribute transfers identically across methods. Attachments, inline images in the body, and the visible text usually carry over; original Sent on timestamps, sensitive classification labels, and certain tracking headers may not reflect the copy action. When exact transport-level fidelity is required (for legal hold or forensic review), copy the .msg file or export the folder rather than rely on in-app duplication.
Behavior by Item Type and Store
- Standard emails: Subject, body text, attachments, inline images carry over.
- Meeting requests and tasks: Often cannot be duplicated via Message Header Copy; use Save & Close or export methods instead.
- Items in PST/OST: Copy methods work while the file is accessible; if offline, verify the copy landed in the correct .pst or .ost container.
- Items under retention hold or sensitivity labels: Copy may be restricted; check policy and permissions.
Practical Use Cases and Alternatives
Common reasons to copy an email include preserving training examples, creating review material, or preparing a sanitized version for sharing with third parties. If your goal is to forward information to a colleague, standard forwarding is simpler; if you need point-in-time preservation for audits, prefer saving a .msg export or using the Message Header Copy method. For workflow automation, explore Outlook add-ins, Power Automate, or Exchange Web Services rather than manual duplication.
Troubleshooting and Limitations
Not all options appear in every version or deployment of Outlook. If a method is missing, check your version, mailbox type, and admin policies. Common issues include disabled Message Header Copy in locked-down organizations, missing Move to Folder controls in some web experiences, and inconsistent handling of inline images between clients. When in doubt, export the message as a .msg file for an exact copy, or verify with your IT or compliance team if retention or eDiscovery rules apply.
