建議您在本教學課程中使用測試原則,讓您不會影響即時原則。We recommend using a testing policy for this tutorial so that you don't affect your live policy.
請確定您已備妥原則名稱,以及 [一般] 標籤的 GUID。Make sure that you have the name of your policy handy, as well as the GUID for your General label.

現在就開始吧。Let's get started.

針對標示為 [一般] 的電子郵件,實作警告訊息Implement a warning message for emails labeled as General

此程序描述如何設定您的原則,以便在 Outlook 使用者傳送標示為 [一般] 的電子郵件之前,先對其發出警告。This procedure describes how to configure your policy to warn Outlook users before they send an email labeled General.

使用者可以選擇留意警告,並變更標籤或內容,也可以選擇傳送電子郵件。The users can choose to heed the warning, and either change the label or the content, or they can choose to send the email anyway.

  1. 在用戶端電腦上,以系統管理員身分執行 PowerShell。On the client machine, run PowerShell as an administrator.

  2. 執行下列命令,以定義 [一般] 標籤的警告訊息。Run the following command, to define a warning message for the General label. 當您複製此命令時,請將 Global 取代為您的原則名稱,並以您自己的標籤識別碼取代字元的長字串。When you copy this command, replace Global with the name of your policy, and the long string of characters with your own label ID.

    Set-LabelPolicy -Identity Global -AdvancedSettings @{OutlookWarnUntrustedCollaborationLabel="8faca7b8-8d20-48a3-8ea2-0f96310a848e"}
    

    在此範例中,原則名為 Global,而 [一般] 標籤的 GUID 是 8faca7b8-8d20-48a3-8ea2-0f96310a848eIn this example, the policy is named Global, and the GUID for the General label is 8faca7b8-8d20-48a3-8ea2-0f96310a848e.

    提示

    如果您想要將此設定套用至多個標籤,請在值中列出其 GUID (以逗號分隔)。If you wanted to apply this setting to multiple labels, list their GUIDs in the value, separated by commas.

  3. 在 Outlook 中測試您的設定:Test your setting in Outlook:

    1. 在您的用戶端電腦上,開啟或重新啟動 Outlook 以提取更新後的設定。On your client computer, open or restart Outlook to pull the updated settings.

    2. 建立新的電子郵件訊息,然後套用 [一般] 標籤。Create a new email message, and apply the General label. 在 [訊息] 工具列中,選取 敏感度按鈕,然後選取 [一般]。

    3. 使用您自己的電子郵件地址定義 [收件者] 欄位,並將 [主旨] 欄位定義為 Testing a warning message for the General label,然後傳送電子郵件。Define the To field with your own email address, the Subject field as: Testing a warning message for the General label, and then send the email.

      您應該會看到下列警告,要求您在傳送電子郵件前先確認。You should see the following warning, asking you to confirm before sending the email. 例如:For example:

      測試 [一般] 標籤的警告訊息

    4. 假設您是錯誤嘗試傳送 [一般] 標籤電子郵件訊息的使用者。Pretend that you're a user who has mistakenly tried to email something that was labeled General. 在此情況下,您會想要留意警告,因此請選取 [取消]。In this case, you want to heed the warning, so select Cancel.

      您的電子郵件不會傳送,而是保持為開啟狀態,讓您可以變更內容或標籤。Your email is not sent, but remains open so that you can either change the content or the label.

    5. 您不需要進行任何變更,且可以決定內容是否適合傳送。There's no need to make any changes, and you can decide that the content is appropriate to send. 再次選取 [傳送]。Select Send again. 這次出現警告時,請選取 [確認並傳送]。This time, when the warning appears, select Confirm and Send.

      電子郵件會隨即傳送。The email is sent.

請繼續執行僅在外部傳送 [一般] 電子郵件時才顯示其警告訊息Continue with Show a warning message for General emails only when they're sent externally.

僅在外部傳送 [一般] 電子郵件時才顯示其警告訊息Show a warning message for General emails only when they're sent externally

此程序描如何將例外狀況新增至您稍早設定的警告訊息,以便只針對外部收件者顯示警告訊息。This procedure describes how to add an exception to the warning message you configured earlier, so that the warning message is only displayed for external recipients.

在內部傳送 [一般] 電子郵件時,不會顯示警告訊息。When sending a General email internally, the warning message is not displayed.

  1. 在用戶端電腦上,以系統管理員身分執行 PowerShell。On the client machine, run PowerShell as an administrator.

  2. 執行下列命令,將您的網域定義為警告訊息的受信任網域。Run the following command to define your domain as a trusted domain for warning messages. 當您複製此命令時,請將 Global 取代為您的原則名稱,並將 contoso.com 取代為您自己的網域。When you copy this command, replace Global with the name of your policy, and contoso.com with your own domain.

    Set-LabelPolicy -Identity Global -AdvancedSettings @{OutlookWarnTrustedDomains="contoso.com"}    
    

    提示

    如果您想要將此設定套用至多個網域 (例如,如果您想要新增受信任的夥伴),請在值中列出其網域 (以逗號分隔)。If you wanted to apply this setting to multiple domains, such as if you wanted to add trusted partners, list their domains in the value, separated by commas.

刪除之後,請重新啟動用戶端電腦上的 Outlook,使其不再以本教學課程中定義的設定進行設定。Once deleted, restart Outlook on the client machine so that it's no longer configured with the settings defined in this tutorial.

後續步驟Next steps

為了加速測試,本教學課程使用了傳送給單一收件者且不含附件的電子郵件訊息。For quicker testing, this tutorial used an email message to a single recipient, and without attachments.

請對多個收件者和標籤套用相同的方法,或將其套用至附件,其中標籤狀態有時對使用者而言較不明顯。Apply the same methods with multiple recipients and labels, or to attachments, where labeling status is sometimes less obvious to users.

例如,建議您在標示為 [公用] 的電子郵件訊息上顯示快顯視窗,但在標示為 [一般] 的電子郵件訊息上附加 PowerPoint 簡報。For example, you may want to have a popup message appear on email messages labeled Public, but have a PowerPoint presentation attached that's labeled General.
