The new Outlook for Windows is a modern tool for managing your emails and calendar. It is designed to be fast and easy to use. It supports many features, including sharing a calendar,  changing language, date, and time format, public a calendar, showing week numbers in Outlook calendar, deleting your search history, exporting your search history, adding or removing events from emails to your Calendar, switching to dark mode, link preview, sound alerts for notifications, turn on or off notifications when Outlook is closed, turn on or off incoming email alert sounds, customizing Calendar alerts, and sharing your work hours and location.

Why use Offline Mode?

Sometimes you might not have an internet connection, such as when you are traveling. Offline mode lets you keep working on your emails and calendar events even when you are not online. It saves a copy of your information directly to your computer. This also makes the app feel faster because it does not have to wait for the internet to load your data.

What happens when you are done?

Once you finish your work offline, Outlook will automatically sync your changes with your email server the next time you connect to the internet. Any emails you wrote or folders you moved will update across all your devices.

How to turn Offline Mode on or off

You can change these settings at any time using the steps below. Note: You do not need special permissions for this, though some corporate computers may restrict these settings.

  1. Open the Outlook app from your Start menu.
  2. Click the Settings (gear) icon in the top right corner.

What can you do while offline?

You can perform many common tasks without an internet connection, including:

  • Reading and organizing your emails.
  • Writing new email drafts.
  • Moving, deleting, or flagging messages.

If you try to do something that requires the internet, Outlook will show you an error message. Your changes will not be saved until you reconnect.
