Change Language, Date & Time in Outlook on Windows 11
Outlook on Windows 11 lets you change both the display language and the format for dates and times.
This means you can choose the language Outlook uses for menus and messages, and how it shows dates like 12/25/2023 or 25/12/2023.
The new Outlook app for Windows 11 works with services like Microsoft 365, Outlook.com, Hotmail, and Gmail.
Sometimes, Outlook’s date and time format doesn’t change automatically when you change the main display language. You need to adjust the date and time settings for Outlook directly. This makes sure dates and times look the way you expect, making emails and calendar events easier to read.
You can set Outlook’s language and its date/time formats separately to best suit your needs.
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 language you understand. You can also adjust how dates and times appear, for instance, by showing the month first or using a 24-hour clock. This helps Outlook function more effectively, regardless of your location or preferences. Here’s how to adjust these settings in the Outlook app on your Windows 11 computer.
The steps below will guide you through the process.
First, open the new Outlook app on Windows 11.
You can do that by clicking Start -> All app -> Outlook app. Or use the Start menu search box to search for Outlook and open it.

When the app opens, click the Settings button (gear on the top right) to proceed.

On the Settings page, click the General tab on the left sidebar and select Language and time on the right.

On the Language and time setting page, select the language you want to use with Outlook using the drop-down caret.

The language you select will usually automatically update the date and time format. For instance, the default date format for the English (United Kingdom) language might be yyyy–dd-mm (2024-09-01), representing 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)

Make your selection and save your changes by clicking the Save button at the bottom when you’re done.
That should do it!
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.
