Outlook Reading View: Change the Reading Pane Layout

To change Outlook’s reading view, adjust the Reading Pane: in classic Outlook for Windows, go to View > Layout > Reading Pane and choose Right, Bottom, or Off. In new Outlook and Outlook on the web, open View > Layout > Reading pane and select a placement or hide it. The Reading Pane controls where message contents appear; it is separate from the inbox’s message-list density and the size of text inside an email.

These steps cover Microsoft 365 Outlook on Windows, plus the web and Mac versions where their controls differ. Menu names can vary slightly as Microsoft updates the interface, but the setting is generally called Reading Pane or Reading pane.

What You’ll Need

Access to Outlook and the mailbox whose layout you want to change.
A desktop browser or Outlook desktop app for the placement options described below. Outlook for iOS and Android opens messages in a full-screen message view and does not offer the same desktop Reading Pane layout choices.
A moment to identify which Outlook version you are using. Classic Outlook for Windows has a traditional ribbon; new Outlook has a redesigned interface and may show a New Outlook label or switch.

Step-by-Step

Open your inbox. Select the mail folder whose message layout you want to change, such as Inbox. The Reading Pane setting affects how you preview messages beside or below the list; it does not change the message itself or move mail between folders. If you use more than one account, check which mailbox is selected before adjusting the layout.
Choose the instructions for your version. The controls differ between classic Outlook for Windows, new Outlook, Outlook on the web, and Outlook for Mac. Follow the matching option below rather than looking for a button that belongs to another version.
In classic Outlook for Windows, open the View tab. On the ribbon, select View, then find the Layout group and select Reading Pane. If the ribbon is minimized, click the View tab to expand it. On a narrow window, the Layout commands may be compressed into a smaller menu, so maximize Outlook or look for a group overflow button.
Choose Right, Bottom, or Off in classic Outlook. Select Right to show the message preview to the right of the message list, Bottom to show it underneath, or Off to hide the pane. The change usually takes effect immediately. Click a message once to see whether its contents appear in the selected position.
In new Outlook for Windows, use the layout menu. Select View on the top menu, open Layout, and choose Reading pane. Pick the available right-side or bottom placement, or choose the option to hide the pane. If your version presents the choices as buttons rather than a submenu, select the one matching the position you want. Return to the message list to confirm the preview appears where expected.
In Outlook on the web, open the layout controls. Select View above the message list, then open Layout and choose Reading pane. Select the right, bottom, or hidden option shown. In some web layouts, you can instead select the Settings gear, choose Mail, then Layout, and change the Reading pane setting there. If you do not see a View menu, use Settings; Microsoft may present the controls differently across accounts or interface rollouts.
In Outlook for Mac, open the View menu. In the macOS menu bar at the top of the screen, select View, then Reading Pane. Choose Right, Bottom, or Off (the wording may appear as Hidden in some releases). This is the Mac equivalent of the Windows layout control, although it is in the app menu rather than the Windows ribbon.
Check how the message list responds. Select a message that is not a draft or a special folder item. With the pane on the right or bottom, a single selection should show its contents in the preview area. With the pane off, open a message by double-clicking it in classic Outlook for Windows, or by selecting it in the message list in new Outlook or the web version.
Adjust the divider if the preview is cramped. When the pane is visible, move the pointer to the boundary between it and the message list. When the resize cursor appears, drag the divider to give either area more room. If the window is too narrow, the pane may feel unusable; maximize Outlook or try the bottom layout before deciding the setting has failed.

Changing the Reading Pane is normally a display preference, not a change to email content. If you switch between several mail folders, check each one: some Outlook versions or folder arrangements can retain different view settings. Also note that opening a message in its own window is a separate action. Changing the pane does not force every message you open to appear in a separate window.

Common Mistakes

Confusing the Reading Pane with the message-list view. Compact, single, and preview-style list arrangements affect how the rows in the inbox look. They are not the same as placing the Reading Pane on the right or bottom. If the list looks too crowded, look for view or density controls instead of repeatedly changing the pane position.
Using steps for the wrong Outlook app. The classic Windows ribbon and new Outlook menus are different, and Outlook on the web can show settings in a different place. Confirm the app before following a path. The classic Windows command is under View and Layout; the Mac command is in the macOS View menu.
Expecting the setting to change text size. The pane position changes the available preview area, not the font size of the email. If text is too small, use Outlook’s zoom or display controls for the message, or your system’s accessibility settings. A wider pane can make long lines easier to read but does not enlarge the type.
Clicking a message when the pane is off and expecting a preview. Off means there is no preview area. Open the message to read it, or turn the pane back on from the View or Layout controls.
Dragging the wrong boundary. The divider can be subtle, especially on a narrow screen. Drag the line between the message list and the preview, not the edge of the Outlook window. If you cannot find it, switch to another pane position and try again.

Tips

Use Right on a wide display. A right-side pane keeps the list and selected message visible together, which is useful when scanning subjects and opening messages one at a time. It works best when the window has enough width for both areas.
Use Bottom on a narrow display. A pane below the list gives the message more horizontal space, which can help with wide tables or long lines. The trade-off is that fewer messages may be visible above it. Resize the divider to balance the two sections.
Choose Off for a list-only inbox. Hiding previews can leave more room for the message list and reduce accidental opening while you are sorting mail. You can still open a message when needed; the setting does not delete or archive anything.
Consider read-status behavior separately. In classic Outlook for Windows, the Reading Pane can mark messages as read after they have been displayed for a chosen time. Find this under File > Options > Advanced, then look for the Outlook panes section and Reading Pane. This setting is distinct from pane placement. Review it if a preview seems to mark messages read unexpectedly.
Keep a consistent arrangement where possible. If the pane seems to change when you enter another folder, switch back to the Inbox and check its layout. If a folder’s view has been customized, changing the global-looking menu may not make every folder appear identical. Adjust the folder that is giving you trouble.

Troubleshooting

The Reading Pane option is missing. Make sure you are in Mail and looking at a message list; other Outlook modules, such as Calendar, have different View controls. In classic Outlook, select the View ribbon tab and check the Layout group. In new Outlook or the web version, look under View and Layout, or use Settings > Mail > Layout. If the app window is narrow, maximize it or open the overflow menu because some commands may be collapsed.

The pane setting changes, but no message appears. Select a normal email in the list, rather than relying on an empty folder, a draft, or a group heading. Check that the pane is not set to Off or Hidden. If the preview area is extremely small, drag its divider. You can also change from Right to Bottom, which may reveal the preview more clearly on a narrow screen.

The layout changes back later. Confirm you changed the setting in the same Outlook version and account you use day to day. New Outlook and Outlook on the web may share some mailbox preferences, while classic Outlook can keep local view customizations. If a particular folder resets, apply the choice while that folder is selected. Restart Outlook once to see whether the preference persists; if it does not, install available Office updates and try again.

A message opens in a separate window instead of the pane. That is not necessarily an error. In classic Outlook, double-clicking a message opens it in its own window; a single click previews it when the pane is on. Close the separate window and select the message once in the list. In new Outlook and web, select a message in the list to display it in the reading area; opening a separate browser window is a different action.

The preview is blank or fails to load. Try another message to determine whether the issue affects one email or the whole mailbox. Refresh Outlook on the web, or close and reopen the desktop app. If only one message fails, open it directly and check whether its contents load there. If the entire mailbox is affected, check your connection and account status, then contact your organization’s support team if the problem continues.

Frequently Asked Questions

Is Reading View the same as the Reading Pane?
In everyday Outlook questions, Reading View usually means the Reading Pane: the area that previews a selected email beside or below the list. It is not a separate document-style reading mode. Outlook’s message-list layout, zoom, and pane placement are separate controls.

Can I put the Reading Pane on the left?
The standard desktop and web choices are generally Right, Bottom, or Off/Hidden. Outlook does not normally offer a left-side placement for the Reading Pane. You can widen or narrow the available areas by dragging their divider.

Can I change the Reading Pane on my phone?
Outlook for iOS and Android does not use the same right-or-bottom desktop pane layout. It shows the mailbox list and opens a selected message in the app’s message view. Change the arrangement on a desktop or in a browser if you need the desktop Reading Pane options.

Does turning the pane off delete or hide my emails?
No. It only hides the preview area. Your messages remain in the mailbox and can be opened normally. Off is useful if you want to see more of the message list or prefer to open each email deliberately.

Why are emails marked as read when I preview them?
Outlook may be configured to mark an item read after it appears in the Reading Pane, or when you select a different item. In classic Outlook for Windows, check File > Options > Advanced > Outlook panes > Reading Pane. New Outlook and web settings can differ, so look in Mail settings for read-status options if the classic path is unavailable.

Will this change apply to every folder and device?
Not always. Some view choices are specific to a folder or app, while certain settings may follow your account in new Outlook or the web version. Check the Inbox and any folder where you want a different arrangement, and verify the layout on another device rather than assuming every version shares the same preference.
