郵件提示MailTips

寄件提醒 」 是指使用者他們正在撰寫郵件時顯示。Microsoft Exchange Server 分析郵件,包括清單中的收件者的地址,並被潛在的問題,它會通知寄件提醒使用者傳送訊息之前。寄件提醒所提供的資訊協助、 寄件者可以調整他們所撰寫的郵件,以免發生非預期的情況下或未傳遞回報 (Ndr) 的郵件。MailTips are informative messages displayed to users while they're composing a message. Microsoft Exchange Server analyzes the message, including the list of recipients to which it's addressed, and if it detects a potential problem, it notifies the user with MailTips prior to sending the message. With the help of the information provided by MailTips, senders can adjust the message they're composing to avoid undesirable situations or non-delivery reports (NDRs).

郵件提示如何運作How MailTips work

寄件提醒 Exchange 實作為 web 服務。用戶端軟體時寄件者所撰寫的郵件,讓 Exchange web 服務呼叫的用戶端存取伺服器以取得寄件提醒的清單。伺服器會回應套用至該郵件的寄件提醒的清單與用戶端軟體給寄件者顯示寄件提醒。MailTips are implemented as a web service in Exchange. When a sender is composing a message, the client software makes an Exchange web service call to the Client Access server to get the list of MailTips. The server responds with the list of MailTips that apply to that message, and the client software displays the MailTips to the sender.

下列無生產力的郵件案例是任何郵件環境中的常見案例:The following unproductive messaging scenarios are common in any messaging environment:

  • 因為郵件違反組織中所設定的限制 (例如郵件大小限制或每個郵件的收件者數量上限) 而產生的 NDR。NDRs resulting from messages that violate restrictions configured in an organization such as message size restrictions or maximum number of recipients per message.

  • 因為將郵件傳送給不存在的收件者、受限制的收件者或信箱已滿的使用者而產生的 NDR。NDRs resulting from messages sent to recipients that don't exist, recipients that are restricted, or users whose mailboxes are full.

  • 傳送郵件給已設定自動回覆的使用者。Sending messages to users with Automatic Replies configured.

所有與使用者傳送郵件有關的案例,都期待能夠傳送郵件,而不是收到表示郵件無法傳送的回應。即使在最合適的案例中 (例如自動回覆),這些事件也會導致喪失生產力。在 NDR 的情況下,這個案例會產生撥打給服務台所需的電話費用。All of these scenarios involve the user sending a message, expecting it to be delivered, and instead receiving a response stating that the message isn't delivered. Even in the best-case scenario, like the automatic reply, these events result in lost productivity. In the case of an NDR, this scenario could result in a costly call to the Help desk.

雖然也有數個案例可以傳送郵件而不發生錯誤,不過卻會造成不需要甚至是令人不悅的結果:There are also several scenarios where sending a message won't result in an error, but can have undesirable, even embarrassing consequences:

  • 傳送到極大型通訊群組的郵件。Messages sent to extremely large distribution groups.

  • 傳送給不適當的通訊群組的郵件。Messages sent to inappropriate distribution groups.

  • 不小心傳送給組織外收件者的郵件。Messages inadvertently sent to recipients outside your organization.

  • 針對以密件副本收件者身分接收的郵件選取 [全部回覆]*Selecting *Reply to All to a message that was received as a Bcc recipient.

藉由在使用者撰寫郵件時告知傳送該郵件的可能結果,即可減少這些問題案例發生的機會。例如,若是寄件者知道所傳送的郵件大小超過企業原則的規定,就不會嘗試傳送該郵件。同樣地,若是通知寄件者他們將要傳送的郵件會傳送給組織外的人士,那麼他們很可能會審慎斟酌郵件的內容和語氣是否適當。All of these problematic scenarios can be mitigated by informing users of the possible outcome of sending the message as they're composing the message. For example, if senders know that the size of the message they're trying to send exceeds the corporate policy, they won't attempt to send the message. Similarly, if senders are notified that the message they're sending will be delivered to people outside the organization, they're more likely to ensure that the content and the tone of the message are appropriate.

Exchange 中的郵件提示MailTips in Exchange

下表列出在 Exchange Server 中可用的郵件提示。The following table lists the available MailTips in Exchange Server.

郵件提示MailTip 可用性Availability 案例Scenario
無效的內部收件者Invalid Internal Recipient
OutlookOutlook
若寄件者新增的收件者似乎是組織內部的收件者卻不存在,就會顯示「無效的內部收件者」郵件提示。The Invalid Internal Recipient MailTip is displayed if the sender adds a recipient that appears to be internal to the organization but doesn't exist.
若寄件者寄送郵件的對象已經離開公司,但其地址因為名稱解析快取或是寄件者 [連絡人] 資料夾中的項目而進行解析時,可能就會發生這種情況。若寄件者所輸入的 SMTP 位址具有經過 Exchange 授權的網域,而且該位址無法解析到現有的收件者,也會發生這種情況。This could happen if the sender addresses a message to a user who is no longer with the company but whose address resolves due to name resolution cache or an entry in the sender's Contacts folder. It can also happen if the sender types an SMTP address with a domain for which Exchange is authoritative and the address doesn't resolve to an existing recipient.
郵件提示會指出無效的收件者,讓寄件者選擇將收件者從郵件中移除。The MailTip indicates the invalid recipient and gives the sender the option to remove the recipient from the message.
信箱已滿Mailbox Full
OutlookOutlook
Outlook Web AppOutlook Web App
若寄件者新增的收件者其信箱已滿,而且您的組織又已經針對超過指定大小的信箱執行「禁止接收」限制,就會顯示「信箱已滿」郵件提示。The Mailbox Full MailTip is displayed if the sender adds a recipient whose mailbox is full and your organization has implemented a Prohibit Receive restriction for mailboxes over a specified size.
郵件提示會指出信箱已滿的收件者,讓寄件者選擇將收件者從郵件中移除。The MailTip indicates the recipient whose mailbox is full and gives the sender the option to remove the recipient from the message.
郵件提示顯示時是準確的。若郵件並非立刻傳送,則郵件提示將每兩小時更新一次。這也會套用至儲存在 [草稿] 資料夾中的郵件和兩小時後重新開啟的郵件。The MailTip is accurate at the time of display. If the message isn't immediately sent, the MailTip is updated every two hours. This also applies to messages that were saved in the Drafts folder and reopened after two hours.
自動回覆Automatic Replies
OutlookOutlook
Outlook Web AppOutlook Web App
若寄件者新增的收件者已經開啟自動回覆功能,則會顯示「自動回覆」郵件提示。The Automatic Replies MailTip is displayed if the sender adds a recipient who has turned on Automatic Replies.
郵件提示會指出收件者已開啟自動回覆,並且顯示 [收件者設定之自動回覆的前 175 個字元。The MailTip indicates the recipient has Automatic Replies turned on and also displays the first 175 characters of the automatic reply configured by the recipient.
郵件提示顯示時是準確的。若郵件並非立刻傳送,則郵件提示將每兩小時更新一次。這也會套用至儲存在 [草稿] 資料夾中的郵件和兩小時後重新開啟的郵件。The MailTip is accurate at the time of display. If the message isn't immediately sent, the MailTip is updated every two hours. This also applies to messages that were saved in the Drafts folder and reopened after two hours.
若您的部分使用者信箱在 Exchange Online 上主控,且出現與 Exchange Online 共存的情況,則表示組織遠端部分之遠端網域物件的設定對處理此郵件提示的方式有直接影響。If part of your user mailboxes are hosted on Exchange Online and you're in a coexistence with Exchange Online scenario, the setting on the remote domain object that represents the remote part of your organization has a direct effect on how this MailTip is processed.
在 Exchange 伺服器上,使用者可以設定不同的自動回覆內部和外部的寄件者。如果設定遠端網域視為內部網域 (透過遠端網域物件上設定_IsInternal_參數$true)、 內部的自動回覆會傳回到不論其信箱所在的組織中的所有使用者。不過,如果遠端網域不設定為內部網域、 內部的自動回覆會傳回給為信箱位於本機網域中的所有使用者和外部的自動回覆會傳回到的使用者的信箱中的遠端網域。In Exchange Server, users can configure different Automatic Replies for internal and external senders. If the remote domain is configured as an internal domain (by setting the IsInternal parameter on the remote domain object to $true), the internal automatic reply is returned to all users in the organization regardless of where their mailbox resides. However, if the remote domain isn't configured as an internal domain, the internal automatic reply is returned to all users whose mailboxes are in the local domain and the external automatic reply is returned to users whose mailboxes are in the remote domain.
自訂Custom
OutlookOutlook
Outlook Web AppOutlook Web App
若寄件者新增的收件者設定了自訂的郵件提示,則會顯示自訂郵件提示。A custom MailTip is displayed if the sender adds a recipient for whom a customized MailTip is configured.

For example, you can create a custom MailTip for a distribution group explaining its purpose to reduce its misuse. For more information, see Configure custom MailTips for recipients.
根據預設,如果寄件者未獲准傳送郵件給該收件者,則自訂郵件提示就不會顯示。在這種情況下,則會顯示「限制的收件者」郵件提示。不過,您可以變更這項設定,使自訂郵件提示也能顯示。By default, custom MailTips aren't displayed if the sender isn't allowed to send to that recipient. In that case, the Restricted Recipient MailTip is displayed. However, you can change this configuration and have the custom MailTip also display.
限制的收件者Restricted Recipient
OutlookOutlook
Outlook Web AppOutlook Web App
若寄件者新增的收件者之傳送限制設定為禁止傳送郵件,則會顯示「限制的收件者」郵件提示。The Restricted Recipient MailTip is displayed if the sender adds a recipient for which delivery restrictions are configured prohibiting this sender from sending messages.
郵件提示會指出不允許寄件者傳送郵件的收件者,讓寄件者選擇將收件者從郵件中移除。同時也會明確通知寄件者,即使送出郵件也不會傳遞。The MailTip indicates the recipient to which the sender isn't allowed to send messages and gives the sender the option to remove the recipient from the message. It also clearly informs the sender that the message won't be delivered if sent.
若限制的收件者是外部收件者,或者通訊群組包含外部收件者,也會對寄件者顯示此資訊。不過,下列郵件提示會遭到擱置 (如果有的話):If the restricted recipient is an external recipient, or if it's a distribution group that contains external recipients, this information is also provided to the sender. However, the following MailTips, if applicable, are suppressed:

若寄件者所撰寫的郵件將送出組織外,就會顯示此郵件提示通知他們,以協助寄件者在措辭、語調和內容上做出正確的決定。This MailTip informs senders if a message they're composing will leave the organization, helping them make the correct decisions about wording, tone, and content.
根據預設,此郵件提示會關閉的。您可以加以開啟使用Set-organizationconfig指令程式。如需詳細資訊,請參閱 <透過組織關聯性的郵件提示By default, this MailTip is turned off. You can turn it on using the Set-OrganizationConfig cmdlet. For details, see MailTips over organization relationships.
若您的部分使用者信箱在 Exchange Online 上主控,且出現與 Exchange Online 共存的情況,則表示組織遠端部分之遠端網域物件的設定對處理此郵件提示的方式有直接影響。If part of your user mailboxes are hosted on Exchange Online and you're in coexistence with an Exchange Online scenario, the setting on the remote domain object that represents the remote part of your organization has a direct effect on how this MailTip is processed.
如果設定遠端網域視為內部網域 (透過遠端網域物件上設定_IsInternal_參數$true)、 此遠端網域中的任何收件者會被視為內部與因此將不會是外部收件者 」 郵件提示顯示。不過,如果遠端網域不設定為內部網域、 收件者於該網域使用者被視為外部和此郵件提示會顯示一則訊息時要包含這些收件者。If the remote domain is configured as an internal domain (by setting the IsInternal parameter on the remote domain object to $true), any recipients in this remote domain will be treated as internal and therefore the External Recipients MailTip won't be displayed. However, if the remote domain isn't configured as an internal domain, the recipients in that domain will be considered external and this MailTip will be displayed when a message is being composed to those recipients.
> [!NOTE]> 撰寫郵件至遠端網域中的通訊群組時,不會評估此郵件提示。> [!NOTE]> This MailTip isn't evaluated when composing a message to a distribution group in the remote domain.

> [!NOTE]> 到期來實作的複雜性,您的組織中連接器上的郵件大小限制並不列入考量。> [!NOTE]> Due to the complexity of the implementation, the message size limits on the connectors in your organization aren't taken into account.

郵件提示限制MailTip restrictions

郵件提示會受到下列限制:MailTips are subject to the following restrictions:

  • 在 Outlook 離線模式下工作時,不支援郵件提示。MailTips aren't supported when working in offline mode in Outlook.

  • 當郵件傳送至通訊群組時,屬於該通訊群組成員的個別收件者的郵件提示就不會進行評估。不過,若有任何成員是外部收件者,則對寄件者顯示通訊群組中外部收件者數目的「外部收件者」郵件提示隨即顯示。When a message is addressed to a distribution group, the MailTips for individual recipients that are members of that distribution group aren't evaluated. However, if any of the members is an external recipient, the External Recipients MailTip is displayed, which shows the sender the number of external recipients in the distribution group.

  • 若傳送郵件給 200 位以上的收件者,則基於效能因素,不會對個別信箱的郵件提示進行評估。If the message is addressed to more than 200 recipients, individual mailbox MailTips aren't evaluated due to performance reasons.

  • 自訂郵件提示會限制為 175 個字元。Custom MailTips are limited to 175 characters.

  • 雖然較舊版本的 Exchange Server 會在其完整複製中填入寄件提醒、 Exchange Online 只會顯示最多 1000 個字元。While older versions of Exchange Server would populate MailTips in their entirety, Exchange Online will only display up to 1000 characters.

  • 若寄件者開始撰寫郵件並任其開啟較長時間,則「自動回覆」和「信箱已滿」郵件提示會每兩小時評估一次。If the sender starts composing a message and leaves it open for an extended period of time, the Automatic Replies and Mailbox Full MailTips are evaluated every two hours.
