This tutorial will show you how to turn on or off conversation view for Mail in the Outlook for Windows app for your account in Windows 10 and Windows 11.
The new Outlook for Windows brings the latest features, intelligent assisted capabilities and a new modern and simplified design to your Outlook app. You can tailor it to your style and do more with new Outlook for Windows.
Starting in June 2023, Microsoft is beginning the process of migrating existing Windows Mail, Calendar, and People users to the new Outlook for Windows.
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. The Mail and Calendar apps will continue to be available via download in the Microsoft Store through the end of 2024. On existing devices, users can switch to the new Outlook for Windows from a toggle in the Mail and Calendar apps.
You can change the appearance of the message list and reading pane. Email in the message list can be displayed as individual messages or grouped by conversation.
By default, when you add most account types to Outlook, your messages are displayed in Conversations. A conversation includes all messages in the same thread with the same subject line.
