Edgeにてepp,vbsファイルがダウンロード後に自動で開かれない

Question

EdgeのAutoOpenFileTypesにてepp,vbsを指定しているがダウンロード後に自動で開かれない状態になっています。

ポリシー設定画面を確認したが特にエラー表示も出ておらず、原因,確認点などをご教示いただけますでしょうか。

また、vbsをダウンロードした際は以下のメッセージが表示されます。

Answer 1

I am sorry. It contains the following sections:

epp and vbs are specified in Edge's AutoOpenFileTypes, but they are not automatically opened after downloading.

I checked the policy setting screen, but there is no particular error display, could you tell me the cause, confirmation points, etc.?

Also, when you download VBS, the following message will be displayed.

It can cause problems with your device. Do you want to keep it?

Answer 2

Hi @梶村 拓海 ,

epp and vbs are specified in Edge's AutoOpenFileTypes, but they are not automatically opened after downloading.

As the AutoOpenFileTypes described,  Files with types that should be automatically opened will still be subject to the enabled Microsoft Defender SmartScreen checks and won't be opened if they fail those checks.  

Also, when you download VBS, the following message will be displayed.

From the screenshot, there is an error on ExemptDomainFileTypePairsFromFileTypeDownloadWarnings policy, which has been obsoleted.  According to Identify and interrupt downloads of potentially dangerous files, the vbs file type is defined as a danger_level of ALLOW_ON_USER_GESTURE. Therefore, you can use ExemptFileTypeDownloadWarnings to specify the filetypes that are allowed to download from specific sites without interruption.

Answer 3

Thank you for your answer. Change it to the ExemptFileTypeDownloadWarnings policy once and try to see if it works properly. I would like to ask another question, but the policy is in error, but there are terminals that can automatically open VBS files and terminals that cannot, and why is there a difference between terminals?

Answer 4

Hi @梶村 拓海,

The ExemptFileTypeDownloadWarnings policy is responsible for the exemption of the download warnings.
Whether the file can be opened automatically, it depends on the AutoOpenFileTypes and AutoOpenAllowedForURLs policies. 

As I said before, Files with types that should be automatically opened will still be subject to the enabled Microsoft Defender SmartScreen checks and won't be opened if they fail those checks. According to the screenshot, the vbs/epf/epp file type will be opened automatically on the "https://fresh2020-dev....." url, not opened automatically on others urls. 

What differences between the terminals? Are the VBS files the same?

You could share some screenshots so that we can understand it better.

Answer 5

It turns out that there is a difference between a device that works properly and a device that does not. Could you please take some time to check the value of AutoOpenAllowedForURLs because it may be causing this event? We will upload a screenshot of a working device.スクリーンショット 2024-01-16_ポリシー画面(正常動作端末).png
