Change Language, Date & Time in Outlook on Windows 11

Language, date, and time settings in Outlook control how your emails, menus, and calendar events appear across the Outlook desktop app on Windows 11. You can set Outlook to display menus in one language while showing dates and times in a different regional format.

The Outlook app links directly with your Windows 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.

Change language, date, and time format in Outlook

You can change Outlook language settings by opening the desktop app, going to Settings, and selecting General and then Language and time. From there, you pick your preferred display language, choose a regional format to update date and time layouts automatically, and save your changes so emails and calendar items match your preferences.

The steps below guide you through the process.

Open the Start menu ⊞, type Outlook, and select the app. Alternatively, access it via Outlook app on the taskbar 🖥️.

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.
