If you recently switched from Classic Outlook to the new Outlook for Windows, you may notice the folder list looks different. The Outbox folder no longer appears in the same place you are used to seeing it. This change happens because the new Outlook uses a different sync engine and folder hierarchy than Classic Outlook. This article shows you exactly where the Outbox folder is located in new Outlook and how to access it when you need to review or resend stuck messages.
Key Takeaways: Finding the Outbox in New Outlook
- Folder Pane > More (three dots) > Folders: Reveals the complete folder list including the Outbox when hidden by the default compact view.
- Send / Receive > Show Outbox: Opens a dedicated Outbox window showing all queued messages with their send status.
- Ctrl+Shift+O: Keyboard shortcut that opens the Outbox directly without navigating through menus.
Why the Outbox Folder Moved in New Outlook
Classic Outlook stored the Outbox as a child folder under your main mailbox in the folder hierarchy. New Outlook uses a cloud-based sync model that reorganizes folders into a flat list. The Outbox is still present but it is hidden by default in the compact folder view. New Outlook also treats the Outbox as a temporary holding area rather than a permanent folder you browse regularly. Microsoft designed this change to reduce visual clutter and align the interface with Outlook on the web.
The Outbox appears only when you have at least one message that has not been sent. If you have no unsent messages, the folder does not show at all. This behavior differs from Classic Outlook where the Outbox remained visible even when empty. Understanding this rule helps you avoid searching for a folder that is simply not displayed.
Steps to Locate the Outbox Folder in New Outlook
You can find the Outbox using one of three methods. Use the method that fits your workflow best.
Method 1: Use the Folder Pane Menu
- Open the Folder Pane
In new Outlook, the folder pane is on the left side of the window. If it is collapsed, click the Folder Pane icon (three horizontal lines) at the top left or press Ctrl+Shift+1. - Click More (three dots)
At the bottom of the folder pane, click the three dots icon labeled More. A menu appears. - Select Folders
From the menu, choose Folders. This switches the folder pane to show the full folder tree including the Outbox. - Find Outbox in the Folder List
The Outbox appears as a separate entry below your main mailbox folders. It is not nested under Inbox or Sent Items. Click Outbox to view any queued messages.
Method 2: Use the Send / Receive Ribbon
- Go to the Send / Receive Tab
Click the Send / Receive tab in the ribbon at the top of the Outlook window. - Click Show Outbox
In the Send / Receive group, click the Show Outbox button. A separate window opens showing only the Outbox contents. - Review or Send Messages
In the Outbox window, you can double-click a message to edit it, or click Send All to send all queued messages immediately.
Method 3: Use the Keyboard Shortcut
Press Ctrl+Shift+O at any time. This shortcut opens the Outbox directly in its own window, regardless of which folder you are currently viewing. This is the fastest method if you use the Outbox frequently.
Common Outbox Issues and How to Handle Them
Outbox Folder Does Not Appear at All
If the Outbox does not appear in the folder list, you likely have no unsent messages. The folder only shows when it contains at least one unsent email. To test this, compose a new message and click Send. If the message stays in the Outbox, the folder will appear immediately. If the message sends immediately, check your send settings in File > Options > Mail > Send messages to ensure the option Send immediately when connected is unchecked if you want to queue messages.
Messages Stuck in Outbox Forever
A message stuck in the Outbox usually indicates a connection issue or a large attachment. Open the stuck message from the Outbox and check the attachment size. Outlook has a default attachment limit of 20 MB in new Outlook. If the attachment exceeds this limit, remove it or compress the file. You can also click Send All on the Outbox window to force a send attempt. If the message still does not send, close Outlook, restart the app, and try again.
Outbox Shows Messages That Already Sent
This can happen when the sync between Outlook and the server is delayed. The Outbox may briefly show a message that has already been sent. Wait a few seconds and press F5 to refresh the folder. If the message remains, click it and press Delete to remove it from the Outbox. The message will still appear in your Sent Items folder.
| Item | Classic Outlook | New Outlook |
|---|---|---|
| Outbox visibility | Always visible even when empty | Hidden when empty, appears only with unsent messages |
| Outbox location | Under the mailbox folder tree | Separate entry in folder list, or accessed via Show Outbox button |
| Keyboard shortcut | Ctrl+Shift+O | Ctrl+Shift+O (same) |
| Send behavior | Send immediately or queue based on Send/Receive settings | Send immediately by default; queue requires disabling immediate send |
Now you know exactly where the Outbox folder lives in new Outlook and how to access it using the folder pane, the Send / Receive ribbon, or the Ctrl+Shift+O shortcut. If you frequently queue messages for later delivery, consider turning off the option Send immediately when connected in File > Options > Mail so your messages stay in the Outbox until you manually send them. This gives you more control over when each message leaves your outbox.
