Microsoft 一開始先根據大螢幕調整版面配置,例如使用清單詳細資料版面配置,在 Outlook 中透過清單詳細資料版面配置查看電子郵件清單,顯示在展開的電子郵件旁。在折疊式裝置或平板電腦上,這兩種檢視畫面會並排顯示,或處於雙窗格模式,以垂直分隔線隔開。使用者現在可以輕鬆瀏覽收件匣和日曆並進行分類,不必在收件匣和會話群組檢視模式之間切換。
在 Teams 應用程式中,當裝置處於橫向模式時,橫跨清單/詳細資料版面配置。因此在大螢幕裝置上,使用者能夠更快、更有效率地存取內容、即時通訊和檔案。
此外,他們也根據文件類型建立了獨特的雙螢幕體驗,讓使用者能夠充分利用空間,例如 Word 的閱讀模式、PowerPoint 的清單詳細資料版面配置,以及 Excel 的延伸畫布。

To achieve that, Microsoft knows it's essential to provide an optimal productivity experience for their customers across all devices they use. With the usage of tablets and foldables exploding for productivity apps, Microsoft has been investing in improving the experiences for the Outlook, Teams, and Office apps to give their users a more desktop-like experience on the go.\n\u003e *Teams has a fair share of users on tablets and foldables, and not having optimized experiences for larger form factors was something customers complained about.*\n\u003e\n\u003e Richa Srivastava, Senior Program Manager, Microsoft\n\nWhat they did\n-------------\n\n[Multi-window mode](/develop/ui/compose/layouts/adaptive/support-multi-window-mode) usage has taken off on large screen devices, and companies such as Microsoft have taken advantage of the additional real estate of large screens to provide better experiences for their users. Microsoft made the Outlook, Teams, and Office apps shine on foldables and tablets by optimizing their layouts and incorporating multi-window and [multi-instance](/develop/ui/compose/layouts/adaptive/support-multi-window-mode#multi-instance) capabilities. \n\n### Optimized layouts for large screens\n\nMicrosoft started by optimizing their layouts to better fit the large screen, such as using the list-detail layout for viewing a list of emails next to an expanded email in Outlook. While on a foldable or a tablet, the two views are displayed side by side, or in dual-pane mode, separated by a vertical divider. Users can now easily go through and triage their inbox and calendar without having to switch between inbox and conversation views. \n\nFor the Teams app, they spanned the list-detail layout for when the device is in landscape orientation. This enabled their users to access their content, chats, and files faster and in a more efficient manner when on large screen devices. \n\nFor Office, they also created unique dual-screen experiences based on the document type to enable their users to take advantage of the real estate, such as a reading mode for Word, a list-detail layout for PowerPoint, and an extended canvas for Excel.\n\n### Support for multitasking\n\nWhile the team improved individual app experiences, they also invested in ensuring the apps work well together. Across Teams, Outlook, and Office, Microsoft implemented multitasking features. They made sure the UI was fully resizable so that the apps could seamlessly be transitioned into split-screen or multi-window mode. This helped pair productivity use cases like having a chat open while also working on a document.\n\nThen the apps added functionality to help users be more productive in multi-window mode, like [drag and drop](https://developer.android.com/guide/topics/ui/drag-drop)---enabling drag and drop for text, files, and messages between apps, messages, and events. \n\nLastly, the Office team added multi-instance support which allows users to have multiple instances of the same app side by side, which is useful when viewing two documents simultaneously. The multi-window mode helps in optimized creation with lighter edits and consumption. For Outlook, they also implemented multi-instance, enabling use cases such as composing an email while also reading another message. \n\nFor Teams, users can simply switch from one chat to another and have meetings that are more efficient.\n\nGiven the legacy of the Microsoft apps along with being a large company, implementing the multi-window experience was a one-month project, while implementing multi-instance took the team two months to complete. The improved experiences and the positive customer reactions were better than the teams had hoped for!\n\nResults\n-------\n\nThrough their efforts, Microsoft has **enabled users to be more efficient and productive** on large screen devices. These investments led to **increased active users and retention,** and **positive customer feedback.** With the success they've seen for these apps, the Microsoft team will be continuing to evolve the user experience for all screens.\n\nGet started\n-----------\n\nLearn more about how you can get started with optimizing your app for [large screens](http://d.android.com/large-screens), and learn more about large screen [app quality](https://developer.android.com/docs/quality-guidelines/large-screens-app-quality)."]]
