Exchange Online 中的遠端網域Remote domains in Exchange Online

有許多原因為何您可能會想要控制類型與您的使用者傳送至您在 Microsoft Office 365 中的 Exchange Online 網域外部的網域的郵件的格式。以下是一些這些原因:There are many reasons why you might want to control the types and the format of messages that your users send to domains outside of your Exchange Online domain in Microsoft Office 365. Here are some of those reasons:

  • 您不想讓使用者將郵件轉寄給其他網域的人。You don't want to let your users forward messages to people on other domains.

  • 您不想從某個您往來的組織收到自動化郵件,例如未傳遞回報和外出回覆。You work with an organization from whom you don't want to receive automatic messages, such as non-delivery reports and out-of-office replies.

  • 您在組織外有一個商業夥伴,而您希望該夥伴與組織外的任何人一樣都收到相同的外出回覆。You have a business partner outside your organization, and you'd like that partner to receive the same out-of-office replies as those received by people inside your organization.

  • 您的使用者經常將郵件傳送到一家支援的電子郵件格式受限的公司,而您想要確保傳送至該組織的所有電子郵件,都是以他們可讀取的格式傳送。Your users frequently send email to a company that supports limited email formats, and you'd like to make sure all emails sent to that organization are sent in a format that they can read.

若要完成這個工作,您可以使用項目已呼叫遠端網域。遠端網域設定覆寫的設定,您的使用者可能會設定在 Outlook 或 Outlook (前身為 Outlook Web App),在 web 上的或您在 Exchange 系統管理中心 (EAC) 或 Exchange Online PowerShell 中設定。例如,使用者可能必須為組織外部的人員設定不在辦公室的回覆,但如果遠端網域的寄件者將郵件傳送給他們,及遠端網域不設為收到不在辦公室的回覆,就會傳送任何不在辦公室的回覆。若要變更的設定,您可以:To accomplish this, you use what's called a remote domain. The remote domain settings override settings that your users might configure in Outlook or Outlook on the web (formerly known as Outlook Web App), or that you configure in the Exchange admin center (EAC) or Exchange Online PowerShell. For example, users might have an out-of-office reply set up for people outside the organization, but if a sender from a remote domain sends mail to them, and the remote domain is not set to receive out-of-office replies, no out-of-office reply is sent. To change the settings, you can:

  • 為特定網域建立遠端網域,並為傳送至該網域的電子郵件設定獨特的屬性。Create a remote domain for a specific domain, and set unique properties for emails sent to that domain.

  • 修改預設遠端網域的設定。如果您未設定其他遠端網域,則預設遠端網域的變更會套用至所有外部網域。如果您還有設定其他遠端網域,則預設遠端網域的變更會套用至其他所有外部網域。Modify the settings for the default remote domain. If you have no other remote domains set up, changes to the default remote domain apply to all external domains. If you have other remote domains set up, changes to the default remote domain apply to all other external domains.

如需有關如何建立和設定遠端網域的指示,請參閱<管理 Exchange Online 中的遠端網域>。For instructions on how to create and configure remote domains, see Manage remote domains in Exchange Online.

減少或增加傳送至其他公司的資訊流量Reducing or increasing information flow to another company

有郵件來自組織外部時將會自動產生幾種回覆。有幾種回覆是由使用者在 Outlook 或 Outlook Web App 中設定,而其他幾種是由管理員設定。因為遠端網域設定會覆寫使用者所做的設定,以及管理員所設定的郵件使用者和郵件連絡人設定,您可以選擇將哪幾種自動回覆傳送至遠端網域的每個人。When a message comes from outside your organization, there are several types of replies that are automatically generated. Some types of replies are set up by users in Outlook or Outlook Web App, and others are set up by admins. Because the remote domain settings override settings configured by users, as well as mail user and mail contact settings configured by admins, you can choose which types of automatic replies are sent to everyone on a remote domain.

如果遠端網域組態禁止將特定類型的回覆 (例如未傳遞回報) 傳送給該網域中的收件者,則雖然會產生回覆,但在傳送之前就會刪除。不會傳送錯誤訊息。例如,如果您關閉預設遠端網域的自動轉寄功能,當使用者嘗試將電子郵件自動轉寄到另一個網域時,他們可以變更設定或建立收件匣規則,但郵件不會轉寄。If a remote domain configuration blocks a specific type of reply, like a non-delivery report, from being sent to recipients in that domain, the reply is generated, but then it is deleted before it is sent. No error message is sent. For example, if you turn off automatic forwarding on the default remote domain, when users try to automatically forward email to another domain, they can change their settings or create the Inbox rule, but their messages won't be forwarded.

下表顯示您在遠端網域中可控制的回覆類型,以及每個遠端網域設定會覆寫的設定。The following table shows the types of replies you can control in a remote domain and the settings that each remote domain setting overrides.

回覆類型Type of reply 描述Description 此遠端網域設定覆寫的個別使用者設定Per-user settings that this remote domain setting overrides
郵件答錄機訊息Out-of-office messages

自動轉寄Automatic forwards
允許或防止將自動轉寄的郵件傳送給遠端網域的人。預設是允許自動轉寄。Allow or prevent automatically forwarded messages to be sent to people on the remote domain. The default is to allow automatic forwarding.
當使用者在遠端網域設定自動轉寄給收件者時,遠端網域設定覆寫 (訊息會封鎖自動轉寄已停用遠端網域時) 的使用者自動轉接設定。使用者可以使用這些方法來設定自動轉接:When users configure automatic forwarding to recipients on a remote domain, the remote domain settings override users' automatic forwarding settings (messages are blocked if automatic forwards are disabled for the remote domain). Users can configure automatic forwarding by using these methods:
在 Outlook 或 Outlook web 上的將郵件轉寄的收件匣規則。深入了解在OutlookOutlook web 上的收件匣規則。Inbox rules in Outlook or Outlook on the web to forward messages. Learn more about Inbox rules in Outlook and Outlook on the web.
在網路上的 Outlook 轉接選項。如需詳細資訊,請參閱將來自 Office 365 到其他電子郵件帳戶的電子郵件轉寄Forwarding options in Outlook on the web. For more information, see Forward email from Office 365 to another email account.
請注意: 當系統管理員使用其他方法來設定為使用者自動轉寄時、 轉寄的郵件不會受到 (郵件轉寄給遠端網域的收件者即使自動轉寄會停用遠端網域設定遠端網域)。例如:Note: When admins use other methods to configure automatic forwarding for users, the forwarded messages aren't affected by the remote domain settings (messages are forwarded to recipients on the remote domain even if automatic forwards are disabled for the remote domain). For example:
使用者的郵件轉寄。如需詳細資訊,請參閱 < Configure 電子郵件轉寄的信箱Mail forwarding for a user. For more information, see Configure email forwarding for a mailbox.

遠端網域的電子郵件寄件者可以要求在郵件送達回條。此遠端網域設定可以覆寫送達回條的寄件者的要求,並防止傳送送達回條。如需送達回條要求的詳細資訊,請參閱新增電子郵件追蹤An email sender on the remote domain can request a delivery receipt on a message. This remote domain setting can override the sender's request for a delivery receipt and prevent the delivery receipt from being sent. For more information about requesting a delivery receipt, see Add tracking to email messages.
未傳遞報告Non-delivery report
允許或防止未傳遞回報 (也就是 Ndr 或彈跳訊息) 傳送給遠端網域的人。預設值是允許傳送未傳遞回報。Allow or prevent non-delivery reports (also known a NDRs or bounce messages) to be sent to people on the remote domain. The default is to allow sending non-delivery reports.
此遠端網域設定為可防止未傳遞回報傳送時無法傳遞郵件的唯一方式。This remote domain setting is the only way to prevent non-delivery reports from being sent when a message can't be delivered.
會議轉寄通知Meeting forward notifications
防止或允許將會議轉寄通知傳送給遠端網域的人。預設是防止傳送會議轉寄通知。Prevent or allow meeting forward notifications to be sent to people on the remote domain. The default is to prevent sending meeting forward notifications.
會議轉寄通知會自動建立和會議參與者將會議轉寄時傳送給會議召集人。一般而言,傳送給會議召集人只有在屬於 Exchange Online 組織的網域。系統管理員可以讓他們能夠傳送至遠端網域上的會議召集人。Meeting forward notifications are automatically created and sent to the meeting organizer when a meeting participant forwards a meeting. Typically, they are sent to meeting organizers only on domains that are part of your Exchange Online organization. Admins can enable them to be sent to meeting organizers on the remote domain.

指定郵件格式Specifying message format

若要確保從您的 Exchange Online 組織傳送的電子郵件與遠端網域中的接收端傳訊系統相容,您可以指定傳送至該遠端網域的所有電子郵件適用的郵件格式和字元集。例如,如果您知道遠端網域不是使用 Exchange,則可以指定永遠不使用 RTF 格式。下表說明郵件格式設定。To make sure that email sent from your Exchange Online organization is compatible with the receiving messaging system in the remote domain, you can specify the message format and character set to use for all email messages sent to that remote domain. For example, if you know that the remote domain is not using Exchange, you can specify to never use Rich Text Format (RTF). The following table describes the message format settings.

設定Setting 描述Description 覆寫的設定Settings that this overrides
RTF 格式 (RTF)Rich Text Format (RTF)
選擇如何格式化郵件:Choose how to format messages:
永遠: 如果遠端網域使用 Exchange,請使用這個值。Always: Use this value if the remote domain uses Exchange.
永不: 如果遠端網域不使用 Exchange,則使用此值。Never: If the remote domain does not use Exchange, use this value.
請遵循使用者設定: 使用之使用者所定義郵件格式設定。如果您不知道遠端網域使用何種電子郵件系統,請使用這個值。Follow user settings: Use message format settings defined by the user. Use this value if you don't know what email system the remote domain uses.
預設值是依照使用者的設定。The default is to follow the user's settings.
有幾個地方可以定義郵件格式: Outlook 或 Outlook 在網頁伺服器和管理員也可以使用Set-mailcontactSet-mailuser指令程式來修改個別寄件者的設定。Message format can be defined in several places: Outlook or Outlook on the web, and the admin can also use the Set-MailContact or Set-MailUser cmdlets to modify settings per recipient.
遠端網域設定會覆寫指定由使用者或管理員設定如需郵件格式和的優先順序的郵件格式設定的詳細資訊,請參閱郵件格式和傳輸在 Exchange OnlineRemote domain settings override settings specified by a user or by the admin. For more information about the message formats and the order of precedence of message format settings, see Message format and transmission in Exchange Online.
MIME 字元集非 MIME 字元集MIME character set and Non-MIME character set
無: 使用郵件中指定的字元集。選取 [從清單中的字元集。 如果郵件並沒有字元集,會使用所選的字元集。根據預設,不指定任何字元集。None: Use the character set specified in the message. Select a character set from the list. If the message does not have a character set, the selected character set is used. By default, no character sets are specified.
這些設定用只有當郵件不包含字元集。支援的字元集的完整清單,請參閱為遠端網域設定支援的字元These settings are used only if the message doesn't include a character set. For a complete list of supported character sets, see Supported character sets for remote domains.

如果您為遠端網域指定特定的郵件格式,則會修改傳送至網域的標頭和郵件內容的格式。If you specify a particular message format for the remote domain, the format of the headers and message content sent to the domain are modified.

其他設定Other settings

您可以使用 Exchange Online PowerShell 來設定其他遠端網域的郵件設定。如需設定的完整清單,請參閱 < Set-remotedomain >You can configure other message settings for remote domains by using Exchange Online PowerShell. For a complete list of settings, see Set-RemoteDomain.

我還需要知道什麼?What else do I need to know?

  • 您只能設定外部網域的遠端網域。如果網域未列在 [Office 365 管理中心] > [網域] 頁面上,則此網域定義為外部。例如,如果 fabrikam.com 是您的其中一個網域,則您無法建立 fabrikam.com 的遠端網域。You can set up a remote domain only for an external domain. A domain is defined as external if it isn't listed on the Office 365 admin center > Domains page. For example, if fabrikam.com is one of your domains, you can't create a remote domain for fabrikam.com.

  • 您無法移除預設遠端網域。You can't remove the default remote domain.

  • 您可以在建立遠端網域時指定所有子網域。You can specify all subdomains when you create a remote domain.
