Microsoft Teams 中的私人頻道Private channels in Microsoft Teams

Microsoft Teams 中的私人頻道為小組內的共同作業建立了焦點空間。Private channels in Microsoft Teams create focused spaces for collaboration within your teams. 只有小組中身為私人頻道的擁有者或成員的使用者,才可以存取頻道。Only the users on the team who are owners or members of the private channel can access the channel. 任何人 (包括來賓) 都可以新增為私人頻道的成員,只要他們已經是小組的成員即可。Anyone, including guests, can be added as a member of a private channel as long as they are already members of the team.

如果要將共同作業限制為需要知道的人員,或是在不另外建立小組來管理已指派特定專案小組的情況下,促進小組人員之間的溝通,您可能會想要使用私人頻道。You might want to use a private channel if you want to limit collaboration to those who have a need to know or if you want to facilitate communication between a group of people assigned to a specific project, without having to create an additional team to manage.

例如,在下列情況中,私人頻道相當實用:For example, a private channel is useful in these scenarios:

  • 小組中的一群人希望能有個專屬空間能共同作業,而不需建立個別小組。A group of people in a team want a focused space to collaborate without having to create a separate team.
  • 小組中的一小群人希望使用私人頻道來討論機密資訊,例如預算、資源、戰略定位等。A subset of people in a team want a private channel to discuss sensitive information, such as budgets, resourcing, strategic positioning, and so on.

鎖定圖示表示私人頻道。A lock icon indicates a private channel. 只有私人頻道的成員才能查看以及參與他們所加入的私人頻道。Only members of private channels can see and participate in private channels that they are added to.

私人頻道建立之後,會連結到父系小組,且不能移至其他小組。When a private channel is created, it's linked to the parent team and can't be moved to a different team. 此外,私人頻道不能轉換成標準頻道,反之亦然。Additionally, private channels can't be converted to standard channels and vice versa.

建立專用通道Private channel creation

依預設,任何小組擁有者或小組成員都可以建立私人頻道。By default, any team owner or team member can create a private channel. 來賓則無法建立。Guests can't create them. 您可以在小組階層和組織層級管理建立私人頻道的功能。The ability to create private channels can be managed at the team level and at the organization level. 使用 原則 來控制您組織中的哪些使用者可以建立私人頻道。Use policies to control which users in your organization are allowed to create private channels. 一旦您設定好原則,小組擁有者就可以在小組的 [ 設定 ] 索引標籤中關閉或開啟成員建立私人頻道的功能。Once you've set the policies, team owners can turn off or turn on the ability for members to create private channels in the Settings tab for a team.

建立私人頻道的人即為私人頻道擁有者,只有私人頻道擁有者可以直接新增或移除頻道中的人員。The person who creates a private channel is the private channel owner and only the private channel owner can directly add or remove people from it. 私人頻道擁有者可以將任何小組成員新增至他們建立的私人頻道,包括來賓。A private channel owner can add any team member to a private channel they created, including guests. 私人頻道的成員有安全的交談空間,而且新成員加入之後,他們可以在該私人頻道中查看所有交談 (甚至是舊的交談)。Members of a private channel have a secure conversation space, and when new members are added, they can see all conversations (even old conversations) in that private channel.

小組擁有者可以查看其小組中所有私人頻道的名稱,也可以刪除小組中的任何私人頻道。Team owners can see the names of all private channels in their team and can also delete any private channel in the team. (已刪除的私人頻道可以在刪除後的30 天內還原。)(A deleted private channel can be restored within 30 days after it's deleted). 小組擁有者無法查看私人頻道中的檔案或私人頻道的交談和成員清單,除非他們是該私人頻道的成員。Team owners can't see the files in a private channel or the conversations and member list of a private channel unless they are members of that private channel.

小組成員只能看到已新增的私人頻道。Team members can only see private channels that they've been added to.

新增及移除擁有者和成員Adding and removing owners and members

如果私人頻道擁有者是一或多個私人頻道的最後一位擁有者,則無法透過 Teams 用戶端將其移除。A private channel owner can't be removed through the Teams client if they are the last owner of one or more private channels.

如果私人頻道擁有者離開您的組織,或從與小組相關的 Microsoft 365 群組中移除,則私人通道的成員會自動升級為私人通道擁有者。If a private channel owner leaves your organization or if they are removed from the Microsoft 365 group associated with the team, a member of the private channel is automatically promoted to be the private channel owner.

如果小組成員離開或從小組移除,該使用者也會從小組中的所有私人頻道離開或被移除。If a team member leaves or is removed from a team, that user will also leave or be removed from all private channels in the team. 如果將使用者新增回小組,則必須將該使用者新增回小組中的私人頻道。If the user is added back to the team, they must be added back to the private channels in the team.

頻道擁有者設定Channel owner settings

每個私人通道都有自己的頻道擁有者可以管理的設定,包括新增和移除成員的功能、新增索引標籤,以及整個頻道的 @mentioning。Each private channel has its own settings that the channel owner can manage, including the ability to add and remove members, add tabs, and @mentioning for the entire channel. 這些設定與父系小組設定彼此無關。These settings are independent of the parent team settings. 私人頻道建立時會繼承父系小組的設定,之後,就可以變更其設定,與父系小組設定互不相干。When a private channel is created, it inherits settings from the parent team, after which its settings can be changed independently of the parent team settings.

私人頻道擁有者可以按一下 [管理頻道],然後使用 [成員] 和 [設定] 索引標籤來新增或移除成員及編輯設定。The private channel owner can click Manage channel, and then use the Members and Settings tabs to add or remove members and edit settings.

管理私人頻道的生命週期Manage the lifecycle of private channels

請參閱 管理團隊私人頻道的生命週期 ,以取得如何管理組織中的專用頻道生命週期的指導方針。See Manage the lifecycle of private channels in Teams for guidance on how to manage the lifecycle of private channels in your organization. 這包括如何控制貴組織的使用者是否能夠建立私人頻道、如何代表小組擁有者建立私人頻道、如何取得所有私人頻道訊息的清單以進行封存和稽核之用,以及其他管理工作。This includes how to control whether users in your organization can create private channels, how to create a private channel on behalf of a team owner, how to get a list of all private channel messages for archiving and auditing purposes, and other management tasks.

私人頻道 SharePoint 網站Private channel SharePoint sites

每個私人通道都有自己的 SharePoint 網站。Each private channel has its own SharePoint site. 單獨的網站是確保專用通道檔案的存取權僅限於專用通道的成員。The separate site is to ensure access to private channel files is restricted to only members of the private channel. 根據預設,這些網站是使用文件庫建立的,而且可透過 網站管理介面輕鬆地增強至完整功能的網站。These sites are created with a document library by default, and can be easily enhanced to a full-featured site through the site management interface. 每個網站都是在與父團隊的網站相同的地理區域中建立。Each site is created in the same geographic region as the site for the parent team. 這些輕量型網站擁有自訂範本識別碼 TEAMCHANNEL#0,可讓您透過 PowerShell 和圖形 API 更輕鬆地進行管理。These lightweight sites have a custom template ID, "TEAMCHANNEL#0", for easier management through PowerShell and Graph API.

私人通道網站會同步處理資料分類,並繼承父小組網站的來賓存取權。A private channel site syncs data classification and inherits guest access permissions from the site of the parent team. 網站擁有者和成員群組的成員資格會與團隊內的私人頻道成員資格保持同步。Membership to the site owner and member groups are kept in sync with the membership of the private channel within Teams. 在 SharePoint 中,對擁有者或成員群組的成員資格所做的任何變更,都會自動在四個小時內還原為私人通道成員資格。Any changes to the membership of Owner or Member groups in SharePoint will be reverted to private channel membership within four hours automatically. 在特定使用者需要存取文件而不需要存取私人頻道訊息的情況下,請將他們新增至網站上的 [訪客] 群組,或新增至與擁有者和成員不同的新群組。In scenarios where certain users need to access documents without needing to access private channel messages, add them to the Visitors group on the site or to a new group that's separate from Owners and Members.

團隊會管理私人頻道網站的生命週期。Teams manages the lifecycle of the private channel site. 如果網站是在小組外刪除,只要私人通道仍在使用中,背景作業就會在四個小時內復原網站。If the site is deleted outside of Teams, a background job restores the site within four hours as long as the private channel is still active. 如果網站遭到永久刪除,就會為專用通道提供新的網站。If the site is permanently deleted, a new site is provisioned for the private channel.

如果已還原私人頻道或包含私人頻道的小組,就會將這些網站還原。If a private channel or a team containing a private channel is restored, the sites are restored with it. 如果私人通道網站已還原,且超過專用通道的30天虛刪除視窗,該網站就會以獨立的網站的方式運作。If a private channel site is restored and it's beyond the 30-day soft delete window for the private channel, the site operates as a standalone site.

私人頻道訊息合規性記錄Private channel message compliance records

在私人頻道中傳送的訊息記錄會傳送到所有私人頻道成員的信箱,而不是傳送到群組信箱。Records for messages sent in a private channel are delivered to the mailbox of all private channel members, rather than to a group mailbox. 記錄的標題會有格式設定,指出寄自哪一個私人頻道。The titles of the records are formatted to indicate which private channel they were sent from.

如需有關以「電子文件探索」搜索私人頻道訊息的詳細資訊,請參閱私人頻道的電子文件探索For more information about performing an eDiscovery search for private channel messages, see eDiscovery of private channels.

私人通道中的檔案存取權注意事項Considerations around file access in private channels

當您在私人頻道中建立新的 OneNote 筆記本時,其他使用者仍然可以存取該筆記本,因為「存取」行為與「和使用者共用私人頻道 SharePoint 網站中任何其他項目」的存取權相同。When a new OneNote notebook is created in a private channel, additional users can still get access to the notebook because the behavior is the same as sharing access to any other item in a private channel SharePoint site with a user.

如果透過 SharePoint 將私人頻道中筆記本的存取權授予使用者,則從小組或私人頻道中移除該使用者並不會移除該使用者對筆記本的存取權。If a user is granted access to a notebook in a private channel through SharePoint, removing the user from the team or private channel won't remove the user's access to the notebook.

如果將現有的筆記本新增為專用頻道的索引標籤,則不會變更對專用通道的存取,且筆記本會保留其現有的許可權。If an existing notebook is added as a tab to a private channel, access to the private channel isn't changed and the notebook retains its existing permissions.

私人頻道限制Private channel limitations

目前,私人頻道支援連接器和索引標籤 (Stream、Planner、Forms 除外)。Currently, private channels support connectors and tabs (except Stream, Planner, and Forms). 我們正致力讓私人頻道支援所有的應用程式,包括傳訊擴充功能和 Bot。We're working on full apps support for private channels, including messaging extensions and bots.

每個小組最多可以有 30 個私人頻道,每個私人頻道最多可以有 250 個成員。Each team can have a maximum of 30 private channels and each private channel can have a maximum of 250 members. 30 個私人頻道限制不計入每個小組 200 個標準頻道的限制。The 30 private channel limit is in addition to the 200 standard channel limit per team.

當您從現有團隊建立團隊時,不會複製現有團隊中的任何私人頻道。When you create a team from an existing team, any private channels in the existing team won't be copied over.
