The new Outlook for Windows brings the latest features with a modern, simplified design to your Windows PC. You can tailor it to your style and do more with the new Outlook for Windows. Learn more about the new Outlook for Windows here.

Beginning in 2024, Windows 11 devices will be shipped with the new Outlook for Windows as the default mailbox application free for all to use. Support for Windows Mail, Calendar, and People will end by December 31, 2024. We are currently in the process of migrating existing users to the new Outlook for Windows.

What to expect

If you have an account that is supported by the new Outlook for Windows, you'll see a toggle in Windows Mail and Calendar to Try the new Outlook in the upper right corner of your screen. Selecting the toggle will start the download of the new Outlook for Windows on your device. This may take several minutes to complete. After the installation completes, Windows Mail or Calendar will close and the new Outlook for Windows will open, where you can sign in and choose to import your accounts and settings. 

If you would like to go back to Windows Mail and Calendar, you can do so by selecting the toggle in the new Outlook for Windows. You’ll be asked to provide feedback on why you're going back – we encourage you to let us know what we can improve about the new Outlook for Windows so that our product team has the chance to address feedback before support for Windows Mail and Calendar ends in 2024.  

To streamline your experience, over the coming months we’ll begin automatically downloading and installing the new Outlook for Windows onto your device. (We’ll notify you before we begin the download.) The next time you open Mail and Calendar, we’ll let you know that we’re launching new Outlook for Windows for the first time. You'll continue to have the option to toggle back to Windows Mail and Calendar. 

If you're not interested in trying the new Outlook for Windows, you can stop using Windows Mail and Calendar and instead manage your email and calendar through your service’s webmail application, or a different email client. Support for Windows Mail, Calendar, and People is ending in 2024 so if you don’t want to use the new Outlook for Windows after trying it, you'll need to move to a different application by the end of 2024. More information on specific end of support dates will be made available in accordance with the Modern Policy for product lifecycles. 

What if one of my accounts is not yet supported? 

The new Outlook for Windows supports the following accounts:

  • Personal Microsoft accounts such as,,, etc.

  • Work or school accounts licensed for Outlook use (this is typically the account assigned to you by your organization's admin and what you use to sign in to Microsoft services at work or school)

  • Third-party accounts such as Gmail, Yahoo!, iCloud

  • Other third-party accounts connecting through IMAP

In the coming months we'll release support for POP connections.

What if I can't find some of my calendar events in the new Outlook for Windows? 

In most cases, if you are using a personal Microsoft account or third-party account like Gmail, Yahoo!, or iCloud, it may take a few minutes for your calendar data to sync to the new Outlook for Windows. You can learn more about ways to troubleshoot here.

If you have been using Windows Mail with only a mailbox connecting through IMAP, your calendar data may be locally saved on your device as the IMAP protocol does not support syncing calendar data to a mailbox. The new Outlook for Windows does not currently support viewing local data from Windows Calendar. You can always access this data by clicking the toggle in the new Outlook for Windows to return to Windows Calendar.
