Exchange Online 中的远程域Remote domains in Exchange Online

有多个原因为什么您可能希望控制类型和您的用户发送到 Microsoft Office 365 中 Exchange Online 域外的域的消息的格式。下面是一些这些原因: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:

  • 您不想让用户将邮件转发给其他域上的用户。You don't want to let your users forward messages to people on other domains.

  • 您与某个组织合作,但不希望接收其自动邮件,例如未送达报告和外出答复。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.

  • 您有一个业务合作伙伴在组织外部,您希望该合作伙伴接收与组织内部用户接收到的相同外出答复。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.

  • 您的用户向支持限制电子邮件格式的公司频繁发送电子邮件,您希望确保发送到该组织的所有电子邮件均使用他们可以阅读的格式。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.

若要完成此任务,您使用所谓的远程域。远程域设置覆盖您的用户可能会在 Outlook 或 (之前被称为 Outlook Web App),在 web 上的 Outlook 中配置或在 Exchange 管理中心 (EAC) 或 Exchange Online PowerShell 中配置的设置。例如,用户可能需要为组织外部的人员-外出答复,但如果远程域未设置接收-外出答复来自远程域的发件人将邮件发送到它们,以及发送任何-外出答复。若要更改的设置,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:

  • 为特定域创建一个远程域,并设置发送到该域的电子邮件的唯一属性。Create a remote domain for a specific domain, and set unique properties for emails sent to that domain.

  • 修改默认远程域的设置。如果您未设置其他远程域,对默认远程域的更改将应用到所有外部域。如果您设置了其他远程域,对默认远程域的更改将应用到所有其他外部域。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.

有关如何创建和配置远程域的说明,请参阅在 Exchange Online 中管理远程域For instructions on how to create and configure remote domains, see Manage remote domains in Exchange Online.

如果邮件来自您的组织之外,有几种自动生成的答复。有些类型的答复由 Outlook 或 Outlook Web App 中的用户设置,其他类型的答复则由管理员设置。因为远程域设置会覆盖用户配置的设置,以及管理员配置的邮件用户和邮件联系人设置,您可以选择向远程域中的所有人发送哪些类型的自动答复。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.

如果远程域配置阻止向该域中的收件人发送特定类型的答复,如未送达报告,将生成答复,但在发送后将删除。不会发送错误消息。例如,如果您在默认远程域上关闭自动转发,则当用户尝试将电子邮件自动转发到其他域时,他们可以更改设置或创建收件箱规则,但邮件不会转发。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.

下表显示了您在远程域中可以控制的答复类型,以及每个远程域设置覆盖的设置。The following table shows the types of replies you can control in a remote domain and the settings that each remote domain setting overrides.

答复类型Type of reply 描述Description 此远程域设置将覆盖的每个用户的设置Per-user settings that this remote domain setting overrides
"外出"邮件Out-of-office messages
指定是否向远程域用户发送外出邮件,如果是,发送哪封邮件。您可以选择域用户为组织外部用户设置的答复,也可以选择为组织内部用户设置的答复。默认设置是发送为组织外部用户设置的外出答复。Specify whether an out-of-office message should be sent to people on the remote domain, and if so, which message to use. You can select either the reply that the user on your domain set up for people outside your organization, or the one for people inside your organization. The default is to send the out-of-office reply for people outside your organization.
此设置将覆盖在OutlookOutlook web 上的单个用户指定的-外出答复设置。This setting overrides out-of-office reply settings specified by individual users in Outlook or Outlook on the web.

允许向远程域用户发送或阻止自动转发的邮件。默认设置是允许自动转发。Allow or prevent automatically forwarded messages to be sent to people on the remote domain. The default is to allow automatic forwarding.
当用户在远程域配置自动转接到的收件人时,远程域设置覆盖 (邮件如果远程域的禁用自动转发阻止) 的用户自动转接设置。用户可以通过使用这些方法来配置自动转接: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 上的转发邮件中的收件箱规则。了解有关Outlook在 web 上的 Outlook中的收件箱规则的详细信息。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 web 上的 Outlook 中的转接选项。有关详细信息,请参阅将转接到另一个电子邮件帐户的 Office 365 中的电子邮件Forwarding options in Outlook on the web. For more information, see Forward email from Office 365 to another email account.
注意: 当管理员使用其他方法来配置的用户自动转发时,转发的邮件不受 (邮件转发到远程域的收件人即使禁用自动转发的远程域设置远程域)。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:
用户的邮件转发。有关详细信息,请参阅配置邮件转发的邮箱Mail forwarding for a user. For more information, see Configure email forwarding for a mailbox.
将邮件转发到邮件流规则 (也称作传输规则)。有关详细信息,请参阅Mail flow 规则 (传输规则) 在 Exchange OnlineMail flow rules (also known as transport rules) to forward messages. For more information, see Mail flow rules (transport rules) in Exchange Online.

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.

指定邮件格式Specifying message format

要确保从 Exchange Online 组织发送的电子邮件与远程域中的接收邮件系统相兼容,您可以指定用于发送到该远程域的所有电子邮件的邮件格式和字符集。例如,如果知道远程域不使用 Exchange,则可以指定从不使用 RTF 格式。下表介绍了邮件格式设置。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.

设置Setting 描述Description 将被覆盖的设置Settings that this overrides
RTF 格式 (RTF)Rich Text Format (RTF)
选择如何设置邮件格式:Choose how to format messages:
始终:如果远程域使用 Exchange,使用此值。Always: Use this value if the remote domain uses Exchange.
从不:如果远程域不使用 Exchange,使用此值。Never: If the remote domain does not use Exchange, use this value.
遵循用户设置:使用用户定义的邮件格式设置。如果您不知道远程域使用何种电子邮件系统,使用此值。 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.

我还需要了解哪些内容?What else do I need to know?

  • 您可以设置仅外部域的远程域。域指外部,如果它未列在Office 365 管理中心 > 页。例如,如果 fabrikam.com 为您的域之一,您无法创建用于 fabrikam.com 远程域。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.

  • 不能删除默认远程域。You can't remove the default remote domain.

  • 当您创建一个远程域时,您可以指定所有子域。You can specify all subdomains when you create a remote domain.
