Office 365 外部共用與 Azure Active Directory B2B 共同作業Office 365 external sharing and Azure Active Directory B2B collaboration

Office 365 (OneDrive、SharePoint Online、整合群組等) 中的外部共用與 Azure Active Directory (Azure AD) B2B 共同作業在技術上而言是相同的。External sharing in Office 365 (OneDrive, SharePoint Online, Unified Groups, etc.) and Azure Active Directory (Azure AD) B2B collaboration are technically the same thing. 所有外部共用 (OneDrive/SharePoint Online 除外),包括 Office 365 群組中的來賓都已使用 Azure AD B2B 共同作業邀請 API 來進行共用。All external sharing (except OneDrive/SharePoint Online), including guests in Office 365 Groups, already uses the Azure AD B2B collaboration invitation APIs for sharing.

Azure AD B2B 與 SharePoint Online 中的外部共用有何不同?How does Azure AD B2B differ from external sharing in SharePoint Online?

OneDrive/SharePoint Online 有個別的邀請管理員。OneDrive/SharePoint Online has a separate invitation manager. OneDrive/SharePoint Online 中的外部共用支援會在 Azure AD 開發其支援之前開始。Support for external sharing in OneDrive/SharePoint Online started before Azure AD developed its support. 隨著時間的經過,OneDrive/SharePoint Online 外部共用已發展出數個功能,而且已有數百萬個使用者使用該產品的內建共用模式。Over time, OneDrive/SharePoint Online external sharing has accrued several features and many millions of users who use the product's in-built sharing pattern. 不過,OneDrive/SharePoint Online 外部共用的運作方式與 Azure AD B2B 共同作業的運作方式有些微差異。However, there are some subtle differences between how OneDrive/SharePoint Online external sharing works and how Azure AD B2B collaboration works. 您可以在外部共用概觀中深入了解 OneDrive/SharePoint Online 外部共用。You can learn more about OneDrive/SharePoint Online external sharing in External sharing overview. 此程序在下列各方面通常會與 Azure AD B2B 不同:The process generally differs from Azure AD B2B in these ways:

  • OneDrive/SharePoint Online 會在使用者兌換其邀請之後,將使用者新增至目錄。OneDrive/SharePoint Online adds users to the directory after users have redeemed their invitations. 因此在兌換前,您不會在 Azure AD 入口網站中看到使用者。So, before redemption, you don't see the user in Azure AD portal. 如果其他網站同時邀請使用者,則會產生新的邀請。If another site invites a user in the meantime, a new invitation is generated. 不過,當您使用 Azure AD B2B 共同作業時,使用者會立即新增於邀請上,因而顯示在每個地方。However, when you use Azure AD B2B collaboration, users are added immediately on invitation so that they show up everywhere.

  • OneDrive/SharePoint Online 中的兌換體驗與 Azure AD B2B 共同作業中的體驗有所差異。The redemption experience in OneDrive/SharePoint Online looks different from the experience in Azure AD B2B collaboration. 在使用者兌換邀請之後,體驗看起來很類似。After a user redeems an invitation, the experiences look alike.

  • 您可以從 OneDrive/SharePoint Online 共用對話方塊挑選 Azure AD B2B 共同作業邀請的使用者。Azure AD B2B collaboration invited users can be picked from OneDrive/SharePoint Online sharing dialog boxes. 在 OneDrive/SharePoint 邀請的使用者兌換其邀請之後,也會出現在 Azure AD 中。OneDrive/SharePoint Online invited users also show up in Azure AD after they redeem their invitations.

  • 授權需求不同。The licensing requirements differ. 對於每個付費的 Azure AD 授權,您最多可讓 5 位來賓使用者存取您的付費 Azure AD 功能。For each paid Azure AD license, you can let up to 5 guest users access your paid Azure AD features. 若要深入了解授權,請參閱 Azure AD B2B 授權以及<SharePoint Online 外部共用概觀>中的「什麼是外部使用者?」To learn more about licensing, see Azure AD B2B licensing and "What is an external user?" in the SharePoint Online external sharing overview.

若要使用 Azure AD B2B 共同作業來管理 OneDrive/SharePoint Online 中的外部共用,請將 OneDrive/SharePoint Online 外部共用設定設為 [只允許與您組織目錄中現有的外部使用者共用] 。To manage external sharing in OneDrive/SharePoint Online with Azure AD B2B collaboration, set the OneDrive/SharePoint Online external sharing setting to Allow sharing only with the external users that already exist in your organization's directory. 使用者可以移至外部共用網站,並從系統管理員新增的外部共同作業者之間選擇。Users can go to externally shared sites and pick from external collaborators that the admin has added. 系統管理員可以透過 B2B 共同作業邀請 API 來新增外部共同作業者。The admin can add the external collaborators through the B2B collaboration invitation APIs.

OneDrive/SharePoint Online 外部共用設定

在啟用外部共用之後,在 SharePoint Online (SPO) 人員選擇器中搜尋現有來賓使用者的功能預設為關閉,以符合舊版的行為。After enabling external sharing, the ability to search for existing guest users in the SharePoint Online (SPO) people picker is OFF by default to match legacy behavior.

您可以使用租用戶和網站集合層級中的 'ShowPeoplePickerSuggestionsForGuestUsers' 設定來啟用此功能。You can enable this feature by using the setting 'ShowPeoplePickerSuggestionsForGuestUsers' at the tenant and site collection level. 您可以使用 Set-SPOTenant 和 Set-SPOSite Cmdlet 來設定此功能,讓成員搜尋目錄中所有的現有來賓使用者。You can set the feature using the Set-SPOTenant and Set-SPOSite cmdlets, which allow members to search all existing guest users in the directory. 租用戶範圍中的變更不會影響已佈建的 SPO 網站。Changes in the tenant scope do not affect already provisioned SPO sites.
