New Outlook Can Now Mimic Outlook Classic’s Design
MS may not admit that New Outlook has significant shortcomings, but it knows that many users still prefer Outlook Classic. To address this, MS has replicated Outlook Classic’s appearance as a theme for New Outlook, hoping that holdouts will finally switch. You can now make New Outlook look like the classic version, although it remains a web app.
A new optional setting in New Outlook for Windows 11 and Windows 10 allows users to apply this classic design as a theme. MS began rolling it out in August 2026, and it has now appeared on my PC.
I navigated to Settings > General > Appearance in New Outlook and enabled “Enable classic Outlook style.” Once activated, New Outlook looked much closer to Outlook Classic.
As soon as you select the option, New Outlook warns that “some settings aren’t available in classic Outlook style.” The entire Themes section—including Copilot themes, image backgrounds, and accent colors—is then disabled. In other words, you can use either the classic appearance or a custom theme, but not both.
New Outlook Remains a Web App
The theme does not change the fact that New Outlook is still a web app running in an Edge-powered container. However, that architecture also helps explain why the themes are so polished.
Because New Outlook is ultimately a website, MS can easily customize its appearance. A combination of CSS and JavaScript can transform the new interface into the design users have known for years.
In testing, Windows Latest observed changes throughout the New Outlook interface that make it resemble Outlook Classic. The title bar, icons, folder list, and ribbon have all been updated to look more like the classic version. This is New Outlook styled as Outlook Classic, and the resemblance is surprisingly close.
Title Bar and Navigation Changes
Even the blue patterned title bar, one of New Outlook’s signature design elements, is gone. In light mode, it is replaced by a plain background that more closely matches Outlook Classic.
MS has also added two small buttons to the top-left corner of the title bar: Send/Receive, which handles synchronization, and Undo. These mimic Outlook Classic’s Quick Access Toolbar. The Outlook logo also switches to the older multicolor icon.
The navigation bar has also been updated, although the changes are relatively minor. MS has made the background darker in dark mode and introduced monochrome outlines for the Mail, Calendar, People, and other app icons. The Calendar view also receives a classic-style theme.
New Outlook currently uses colorful icons, so replacing them and darkening the background helps recreate the Outlook Classic appearance.
Classic-Inspired Calendar Design
The Calendar ribbon also borrows from Outlook Classic. It includes “Today” and “Next 7 Days” buttons under a new “Go to” group, along with an “Add” button under “Manage Calendars.” These replace New Outlook’s Filter, Split View, and Print buttons. Calendar now includes a Folder tab as well.
In a support document reviewed by Windows Latest, MS confirmed that it is focusing on iconography and typography to bridge the gap between the two applications.
“When enabled, the setting applies coordinated changes across the Outlook experience, including visual styling, layout, typography, icons, and selected interactions,” MS explained. “This update is designed to help users who are transitioning from classic Outlook by providing a more familiar experience while maintaining the capabilities of the new Outlook.”
More Compact Folder and Message Lists
MS has redesigned the mail folder list to make it more compact, similar to Outlook Classic. Icons no longer appear beside individual folders such as Inbox, Drafts, and Sent Items.
The text is smaller, and the Favorites section now displays the full account name beside each Inbox instead of truncating it. I also noticed a new “Shared with me” section under my work account. Like Outlook Classic, it lists the shared mailboxes I can access.
The email list has also adopted one of my favorite Outlook Classic behaviors. Instead of grouping messages by month, New Outlook now organizes them into categories such as “Yesterday,” “Wednesday,” “Sunday,” “Last Week,” “Two Weeks Ago,” and “Last Month.” Each email also displays the day beside the date, such as “Wed 9/30/2026.”
Ribbon Tabs and Controls
The ribbon, one of the most noticeable parts of the interface, also receives familiar design changes. In Mail view, Send/Receive and Folder tabs now appear alongside File, Home, View, and Help. The blue “New mail” button becomes a neutral “New Email” button with a separate “New Items” drop-down menu, while also adopting Outlook Classic’s iconography.
The Send/Receive tab is currently basic, offering only two buttons: “Send/Receive All Folders” and “Work Offline.” The Folder tab includes New Folder, New Search Folder, Add to Favorites, and Folder Pane options.
The Home tab also includes a “Groups” section with New Group and Browse Groups, as well as a “Send to OneNote” button. Both were part of Outlook Classic’s ribbon.
The View tab has changed as well. It now includes “Use Tighter Spacing,” “Conversation Settings,” and a “To-Do Bar” option, offering another throwback to Outlook Classic.
Classic Styling in the Compose Window
Finally, the compose window receives the same Outlook Classic-inspired treatment. Across the top, you will find Message, Insert, Format Text, Draw, and Options tabs, with formatting controls displayed in the ribbon below.
Final Assessment
I could continue listing every change, but it is clear that MS has done a good job of bringing Outlook Classic’s appearance to New Outlook. However, one major issue remains: MS still needs to restore a native Outlook application, because the current version remains a RAM-intensive Edge instance.
