Change Language, Date & Time in Outlook on Windows 11
Language, date, and time settings in the new Outlook app on Windows 11 control how your emails, menus, and calendar events appear on screen. You can set Outlook to display menus in one language while showing dates and times in another regional format.
The Outlook app links directly with your Windows 11 system language, but you can change these settings manually if your calendar or inbox fails to update automatically. Adjusting these options ensures your emails and meeting invites match your local standards and calendar habits.
Open Outlook, click the Settings gear icon, go to General, select Language and time, choose your language, adjust date/time formats if needed, and click Save. This only affects Outlook, not your Windows operating system.
Change language, date, and time format in Outlook
Changing Outlook’s language settings helps ensure emails and calendar entries appear in a familiar language. Users can also adjust date and time layouts, such as prioritizing the month or enabling a 24-hour clock. This keeps the application functional regardless of location or preference. The following steps outline how to adjust these configurations inside the Outlook app on Windows 11.
The steps below guide you through the process.
Launch the new Outlook app on Windows 11 by clicking Start - All app - Outlook app from the taskbar . Alternatively, type Outlook into the Start menu search box and open the application.

Click the Settings button featuring a gear icon in the top-right corner.

Select the General tab on the left sidebar of the Settings page, then click Language and time on the right pane.

Open the drop-down menu on the Language and time settings page to pick the preferred language for Outlook.

Choosing a new language typically updates date and time formats automatically. Selecting English (United Kingdom), for instance, applies the default yyyy--dd-mm (2024-09-01) date layout for September 1, 2024.
Additional options for a specific language are:
- d/m/yy (1/9/24)
- dd/mm/yyyy (01/09/2024)
- dd/mm/yy (01/09/24)
- d.m.yy (1.9.24)

For the same English (United Kingdom) language, the default time format representing a 12-hour display is hr:mm AM/PM (1:01 AM - 11:59 PM).
Additional options available are:
- hh:mm - hh:mm (24-hour display)
- h:m - h:m (24-hour display)
- hh:mm (12-hour display)
- h:m (12-hour display)

Confirm the configuration by clicking the Save button at the bottom of the window.
That completes the process.
Conclusion:
- Modifying language, date, and time formats in Outlook on Windows 11 can greatly enhance communication and productivity, catering to personal preferences, regional standards, and professional requirements.
- By accessing the Language and Time settings in Outlook, users can easily select their preferred language and choose from a range of date and time format options.

- Adhering to one's preferred date and time display can streamline scheduling and deadline management, aligning with individual comfort and regional practices.
- The process empowers users to tailor their Outlook experience, optimizing efficiency and user experience within the application.
