How to Add Events to Windows 10 Calendar Using New Outlook

If you want to add events to a calendar on Windows 10 today, use the new Outlook for Windows rather than the old built-in Calendar app. Microsoft ended support for Windows Mail, Calendar, and People on December 31, 2024, and those apps can no longer send or receive email or calendar events. New Outlook is the supported replacement and is available on Windows 10 version 17763.0 or later.

If the old Calendar app is still installed, opening it may direct you to Outlook. You can also install new Outlook from the Microsoft Store. Microsoft explains the transition in its Mail and Calendar retirement notice and its new Outlook setup guide.

How to add an event to Windows 10 Calendar

1. Open new Outlook. If it is not installed, get it from the Microsoft Store. Sign in with the account whose calendar you want to use.
2. Select Calendar in the left navigation pane.
3. Select New Event. You can also select a time slot in the calendar and open the full event editor.
4. Enter the event details. Add a title, date, start and end times, location, description, reminder, and repeat schedule as needed.
5. Choose Save or Send. Use Save for a personal appointment. If you add attendees, Outlook treats it as a meeting and sends invitations when you select Send.

Microsoft's current Outlook calendar instructions also support inviting attendees, adding a location, creating recurring events, and using Scheduling Assistant when that feature is available for the account.

Add attendees or make it a Teams meeting

For a meeting, enter one or more people in the attendee field. If your account supports Microsoft Teams, you can turn on the Teams meeting option before sending the invitation. Outlook adds the meeting information to the invitation after you send it.

Set the reminder, recurrence, and calendar

Use the reminder control to choose when Outlook should alert you. For repeating appointments, use the repeat menu. If several calendars are connected, select the calendar you want before saving so the event is stored in the correct account rather than another personal or work calendar.

Use more than one calendar

New Outlook can display multiple calendars at the same time. Check or clear the calendars in the left pane to control what appears in the main view. This is useful when you keep work, personal, family, or other calendars separate.

Add Google, iCloud, Yahoo, or another account

New Outlook supports Microsoft accounts, Microsoft 365 work or school accounts, Gmail, Yahoo, iCloud, and other supported account types. To add another calendar account:

1. Open View settings, or use File > Account info if that option appears in your build.
2. Go to Accounts > Your accounts.
3. Select Add Account.
4. Enter the email address, select Continue, and complete the provider's sign-in and permission prompts.

See Microsoft's account setup instructions for Outlook for Windows for current provider-specific guidance. Some services may ask you to approve access in a browser or use an app-specific password.

Edit or delete an event

Select an existing event to open it. Change the details and select Save, or select Delete to remove it. For meetings with attendees, Outlook may ask whether an update or cancellation should be sent. For a recurring series, choose carefully whether you are changing one occurrence or the entire series.

What happened to the old taskbar event shortcut?

Older Windows 10 builds let you click the taskbar clock and create an event directly from the calendar flyout. That workflow belonged to the retired Windows Calendar experience and should not be the primary method now. Open new Outlook and create the event there instead.

Windows 10 itself reached end of support on October 14, 2025. PCs still run, but standard technical assistance and regular security updates have ended unless the device is covered by an applicable Extended Security Updates program. Microsoft provides the current status on its Windows 10 end-of-support page.
