Microsoft 團隊中的保留原則Retention policies in Microsoft Teams

Microsoft 365 的保留原則和保留標籤可協助您更有效率地管理組織中的資訊。Retention policies and retention labels from Microsoft 365 help you to more effectively manage the information in your organization. 您可以設定保留設定,以保留遵守貴組織的內部原則、行業法規或法律需求所需的資料。You can configure retention settings to keep data that's needed to comply with your organization's internal policies, industry regulations, or legal needs. 您也可以設定保留設定,以刪除被視為債務的資料、您不再需要保留的資料,或是沒有任何法律或業務價值的資料。You can also configure retention settings to delete data that's considered a liability, that you're no longer required to keep, or that has no legal or business value.

團隊支援聊天和通道訊息的保留原則,以便管理員決定是否要保留這些資料、刪除該資料,或保留一段特定的時間,然後刪除。Teams supports retention policies for chat and channel messages so that as an admin, you can decide proactively whether to retain this data, delete it, or retain it for a specific period of time and then delete it. 您可以將團隊保留原則套用到整個組織或特定的使用者與團隊。You can apply a Teams retention policy to your entire organization or to specific users and teams. 小組不支援保留標籤。Retention labels aren't supported for Teams.

團隊保留原則的運作方式How Teams retention policies work

團隊聊天訊息會儲存在聊天中每位使用者信箱的隱藏資料夾中,而團隊頻道訊息則會儲存在小組的群組信箱中類似的隱藏資料夾中。Teams chat messages are stored in a hidden folder in the mailbox of each user included in the chat, and Teams channel messages are stored in a similar hidden folder in the group mailbox for the team. 若要保留受保留原則制約的郵件,內容的複本會自動保留在名為 SubstrateHolds 的隱藏資料夾中,做為 [Exchange 可復原的 專案 ] 資料夾中的子資料夾。To retain messages that are subject to a retention policy, a copy of the content is automatically kept in a hidden folder named SubstrateHolds as a subfolder in the Exchange Recoverable Items folder. 在這些郵件從 SubstrateHolds 資料夾中永久刪除前,這些訊息會保持透過 eDiscovery 工具的搜尋。Until these messages are permanently deleted from the SubstrateHolds folder, they remain searchable by eDiscovery tools.

如需小組保留原則所包含及排除之內容的詳細資訊,以及這些原則的運作方式,請參閱 瞭解 Microsoft 團隊的保留情況。For detailed information about what's included and excluded for Teams retention policies, and how these policies work depending on your policy configuration, see Learn about retention for Microsoft Teams.

注意

這個頁面會說明為何保留原則刪除郵件時,可能會發生延遲。That page explains why you might sometimes see delays when retention policies delete messages. 例如,郵件在保留原則中設定的到期期限之後,最多可顯示7天。For example, messages can be visible up to 7 days after the expiration period you've configured in the retention policy.

如果您使用不同的保留設定設定多個小組保留原則,保留原則會解決任何衝突。If you set up multiple Teams retention policies with different retention settings, the principles of retention resolve any conflicts. 例如:For example:

  • 如果在保留或刪除相同內容時發生衝突,該內容會一直保留下來。If there is a conflict between retaining or deleting the same content, the content is always retained.
  • 如果您保留相同內容的時間有多長,則會保留較長的保留期間。If there is a conflict in how long to retain the same content, it is retained for the longest retention period.

當您有多個小組保留原則時,這些保留位址的兩個原則可能會產生大多數衝突,但如需詳細資訊,請參閱 保留原則或優先順序為何?These two principles of retention address most conflicts that might arise when you have multiple retention policies for Teams, but for more information, see The principles of retention, or what takes precedence?

何時使用小組的保留原則When to use retention policies for Teams

在許多情況下,組織會考慮使用私人聊天資料,而不是頻道訊息,通常是更多與專案相關的交談。In many cases, organizations consider private chat data as more of a liability than channel messages, which are typically more project-related conversations.

您可以針對私人聊天 (1:1 或1:設定個別的保留原則,) 與頻道訊息。You can set up separate retention policies for private chats (1:1 or 1:many chats) and channel messages. 您也可以設定適用于組織中特定使用者或團隊的唯一原則。You can also configure unique policies that apply to specific users or teams in your organization. 針對 [團隊聊天],您可以選取要套用原則的使用者。For Teams chats, you can select which users the policy applies to. 針對團隊頻道訊息,您可以選取要套用原則的小組。For Teams channel messages, you can select which teams the policy applies to.

例如,對於頻道訊息,您可以將一年刪除原則套用到貴組織中的特定小組,並將三年的刪除原則套用至所有其他團隊。For example, for channel messages, you can apply a one-year deletion policy to specific teams in your organization and apply a three-year deletion policy to all other teams.

建立及管理團隊的保留原則Create and manage retention policies for Teams

若要建立小組聊天與頻道訊息的保留原則,請使用 小組位置的保留原則中的指示。To create a retention policy for Teams chats and channel messages, use the instructions from Retention policy for Teams locations.

此頁面包含有關在 Microsoft 365 中建立及管理其他工作負荷之保留原則的其他相關資訊。That page has additional information about creating and managing retention policies for other workloads in Microsoft 365. 例如,您可能會想要為 Microsoft 365 群組建立保留原則,以保留並刪除在小組中存取並儲存在 OneDrive 或 SharePoint 中的檔案。For example, you might want to also create a retention policy for Microsoft 365 Groups to retain and delete files that are accessed in Teams and stored in OneDrive or SharePoint.

使用者體驗End user experience

針對私人聊天 (1:1 聊天) 或群組聊天,最終使用者將會看到舊版的聊天與保留原則設定會被刪除,而「我們已刪除您組織的保留原則」等「我們已刪除較舊的郵件」的控制訊息會顯示在尚未刪除的郵件上。For private chats (1:1 chats) or group chats, the end users will see that chats older than the retention policy configuration are deleted and a control message stating "We've deleted older messages due to your org's retention policy" is shown on top of yet undeleted messages.
