有些網頁必須要用IE才能正常顯示，如果透過EDGE，就要啟用裡面的IE模式才行。
可以直接在EDGE設定中加入要用IE模式開起的網頁，但這有個缺點，要一台一台做，而且還有期限，預設30天，最長可以改到90天，不適合在公司裡這樣設定。
這時就可以用GPO來佈署，步驟如下:
1. 確認GPO裡有EDGE設定，因為DC都是2012版的，所以要自己下載ADMX檔來增加EDGE功能，方式可參考 https://www.anoopcnair.com/download-microsoft-edge-admx-group-policy-templates/
2. GPO裡有EDGE設定後，要啟用兩個設定
設定企業模式網站清單-這個先設定好檔案路徑跟檔名，例如
C:\ielist.xml，這個檔案在第3步會產生。
再來是要啟用設定InternetExplorer整合。
3. 安裝Enterprise Mode Site List Manager，透過這個檔案把要用IE模式開啟的網站建成一個xml的清單，取名成ielist.xml，派送到使用者電腦C槽中，跟第2步GPO裡的設定配合。清單的設定方式一樣網路上很多教學，可參考https://www.anoopcnair.com/configure-enterprise-mode-site-list-using-intune/
4.上述都設定好後，GPO佈署下去就ok了。
當用EDGE開啟IE模式的網站，看一下網址例左邊有出現一樣IE的檔案，就表示現在已在IE模式下執行，設定成功。

Using IE Mode to Open Websites in EDGE on Windows 10
Some websites require Internet Explorer (IE) to be displayed correctly. If you're using EDGE, you can enable the built-in IE mode to access these websites. While you can manually add websites to open in IE mode within EDGE settings, this method has its drawbacks. It requires configuring each device individually and has a time limit, typically set to 30 days (extendable up to 90 days), which is not ideal for company-wide settings.
To address this, you can deploy the settings using Group Policy Objects (GPO) with the following steps:
1.Ensure that the GPO includes the EDGE settings. Since the domain controllers are running the 2012 version, you'll need to download the ADMX files to add EDGE functionality. You can refer to the following link for the process: link to download ADMX files.
2.Once the EDGE settings are available in the GPO, enable two specific settings:
3.Configure the Enterprise Mode Site List: Set the file path and name, for example, C:\ielist.xml. This file will be generated in the next step.
Enable the Internet Explorer Integration setting.
Install the Enterprise Mode Site List Manager. Using this tool, create an XML list named ielist.xml that contains the websites to be opened in IE mode. Place the file in the C:\ directory of users' computers and align it with the settings from step 2. There are various tutorials available online on how to configure the list. You can refer to this link: link to configure Enterprise Mode Site List using Intune.
4.Once all the settings are configured, deploy the GPO to the desired devices.
To verify if a website is opened in IE mode using EDGE, check the URL. If you see the IE file icon on the left side, it indicates that the website is being accessed in IE mode, confirming the successful configuration.
