Good afternoon.

I made a question on MS Communities (https://answers.microsoft.com/en-us/outlook_com/forum/all/disable-and-grey-out-automatic-download-options/15199a59-0570-4705-8644-3db59fdfc0d2) regarding the configuration of Automatic Downloads and Attachments Handling in Outlook using registry settings, GPOs or MDM Configuration profile.

Could you tell me if there is any way of uncheck and grey out the options described in the link?

Best regards

Edited

In case it is not clear this is what I need to change

1.- Remove and grey out

2.- Grey out

As you can see there are things that have been already disabled but there are many that I cannot find how

    Hi @Samael Ambrona Rodriguez ,

    According to my and research and test, I have found some related Group Policy controls some of the buttons you mentioned.
    Go to User Configuration > Administrative Templates > Microsoft Outook 2016 > Outlook Options > Preference > E-mail Options, Unconfigure the "Do not allow attachment preview" to make the option "Turn off Attachment Preview" not greyed out.

    Go to User Configuration > Administrative Templates > Microsoft Outook 2016 > Security > Automatic Picture Download Settings, enable the "Display pictures and external content in HTML e-
    mail", and "Do not permit download of content from safe zones", the option in picture below will be unchecked and greyed out.

    However, I'm afraid there is not a setting for option "Don't download the pictures in encrypted or signed HTML email messages".
    Hope above can help you!

    Dear @Faery Fu-MSFT

    Thank you for your answer.

    Those are the options that I have configured however, there is something that I don't understand. According to your pictures

    You have these two enabled, however according to documentation (see picutre below) Shouldn't it be disabled to avoid Outlook downloading the documents automatically?
