The new Outlook for Windows app offers a modern look and works with Microsoft 365, Outlook.com, Hotmail, and Gmail accounts. It includes many helpful tools like email signatures, external email accounts, out-of-office automatic replies, email sorting, subscription management, email forwarding, setting default From address, backing up your mailbox, changing the reading pane, opening a new window for a message, language translations, turn text predictions on or off, switch primary account, and sharing a calendar.
Why change these settings?
You might want to change these settings if you work with international teams, have specific regional requirements, or simply prefer a different date and time format for better organization.

Note: No administrator privileges are required to change these settings within the app.
First, open the new Outlook app on Windows 11. You can open it by clicking Start, selecting All apps, and choosing Outlook, or by searching for “Outlook” in the Start menu.

When the app opens, click the Settings button (the gear icon) located in the top right corner.

In the Settings menu, click the General tab on the left, then select Language and time on the right.

On the Language and time page, use the drop-down menu to pick your preferred language.

Choosing a language usually updates the date and time format automatically. If you need to adjust them further, you can select specific formats from the lists provided. For example, the United Kingdom settings offer several date formats like dd/mm/yyyy.

You can also adjust the time format, such as choosing between a 12-hour or 24-hour clock for a 12-hour display display.

Once you have finished your selections, click the Save button at the bottom of the screen.
Summary
Customizing your language and time settings in Outlook helps you stay organized and communicate clearly. By following these steps, you can tailor the app to match your regional standards or personal preferences, making your daily scheduling and messaging more efficient.
