Microsoft has announced the retirement of its Microsoft 365 companion apps, setting a December 16 deadline for IT administrators to manually uninstall the software from managed devices. The move places the operational burden of removal entirely on IT teams.
The Calendar, People, and Files companion apps are scheduled for retirement on December 16. This is not an automatic update; Microsoft is explicitly requesting that administrators proactively remove the applications from their device fleets. The company states that all the core functionality of these lightweight apps is already available within the flagship Outlook and Teams clients, making the standalone companions redundant.
For IT administrators managing Microsoft 365 environments, this announcement triggers an immediate operational mandate. Without a coordinated cleanup project, organizations risk having defunct software remain on devices past the deadline, creating unnecessary clutter and potential security oversights.
Key Considerations for the Cleanup Project
- Audit & Inventory: The first step is to identify all managed Windows devices where the companion apps are installed. Management platforms like Microsoft Intune or SCCM can be used to generate a comprehensive inventory.
- Silent Uninstall Packages: IT teams should develop and test silent uninstallation scripts or packages to remove the apps without requiring user interaction or causing disruption.
- Phased Deployment: A scheduled rollout, potentially starting with a pilot group, is recommended to complete the uninstallation well before the December 16 cutoff.
- User Communication: While the change has minimal end-user impact, it is advisable to inform employees that the companion apps are being removed and to direct them to use Outlook and Teams for their calendar, contacts, and file access.
This retirement aligns with Microsoft's broader strategy to reduce application sprawl and consolidate development efforts into its primary productivity platforms. The transition underscores the critical importance of proactive endpoint management, as the responsibility for this change rests solely with IT operations.
微軟宣布將停用 Microsoft 365 附屬應用程式，並設定12月16日為期限，要求IT管理員須從受管理裝置上手動解除安裝相關軟件。此舉將移除操作負擔完全交由IT團隊承擔。
「日曆」、「聯絡人」及「檔案」附屬應用程式將於12月16日停用。這並非自動更新；微軟明確要求管理員主動從其設備群組中移除這些應用程式。公司表示，這些輕量級應用程式的所有核心功能已內建於主要的Outlook及Teams客戶端中，因此獨立附屬應用程式已顯多餘。
對於管理Microsoft 365環境的IT管理員而言，此公告意味著立即需執行操作指令。若未進行有組織的清理專案，機構可能面臨已失效軟件在期限過後仍留存於裝置上的風險，造成不必要的雜亂及潛在的安全疏忽。
清理專案的關鍵考量
- 審計與盤點： 首要步驟是識別所有已安裝附屬應用程式的受管理Windows裝置。可使用如Microsoft Intune或SCCM等管理平台生成全面盤點清單。
- 靜默解除安裝套件： IT團隊應開發並測試靜默解除安裝腳本或套件，以無需使用者互動或造成干擾的方式移除應用程式。
- 分階段部署： 建議安排分階段推行，或可先從試點群組開始，務求在12月16日截止日期前完成解除安裝。
- 使用者溝通： 雖然此變動對終端使用者影響甚微，但仍建議通知員工附屬應用程式即將被移除，並指引他們使用Outlook及Teams處理日曆、聯絡人及檔案存取。
此次停用符合微軟減少應用程式過度擴張的整體策略，並將開發資源整合至其主要生產力平台。這次過渡突顯了前瞻性終端裝置管理的關鍵重要性，因變動責任完全落在IT營運團隊身上。
