Microsoft has begun rolling out a Classic Outlook theme for users of its New Outlook on the web and for Windows. This move is part of Microsoft’s effort to make the transition from classic Outlook to the new version more manageable, especially for those who are accustomed to the familiar interface. The Classic Outlook theme will become available to all users, but it won’t override any existing administrator configurations or automatically migrate users from classic Outlook to the new one.
The rollout is scheduled to start in mid-August and is expected to be completed by the end of September. However, the Classic Outlook theme will only become generally available worldwide between late September and late October. This staggered release allows Microsoft to fine-tune the feature and ensure a smooth experience for users. When enabled, the Classic Outlook theme applies coordinated changes across the Outlook experience, including visual styling, layout, typography, icons, and selected interactions.
For those who are still adjusting to the New Outlook, this new theme will offer a more familiar environment that maintains the capabilities of the new version. The feature can be turned on or off at any time from Settings > General > Appearance, giving users complete control over their interface preferences. Notably, the Classic Outlook theme won’t be enabled by default for most users; instead, it will be available as an option.
This move is part of a broader effort by Microsoft to phase in its New Outlook client, which replaced Windows Mail as a pre-installed app on Windows 11 and Windows starting from October 2023 and January 2025, respectively. While the New Outlook has made significant strides since its introduction in May 2022, some users may still find it daunting due to the lack of certain features available in classic Outlook.
The Classic Outlook theme is a strategic step by Microsoft to address user concerns and make the transition more palatable. By providing an option for users who prefer the classic interface, Microsoft is acknowledging that change can be difficult and giving users flexibility. As technology continues to evolve, companies like Microsoft must balance innovation with user comfort, ensuring that their products meet the needs of their customers.
For those considering the Classic Outlook theme, it’s essential to understand that this feature won’t automatically migrate you from classic Outlook to the new version. Instead, it will offer a more familiar interface while still providing access to the capabilities of New Outlook. As Microsoft continues to refine its services, users can rest assured that their options are being taken into account.
