Turn off Protected View via GPO in Office 365

I want to enable a group policy so that files opened (in Word, Excel, etc) from a network location do not open in "Protected View". We're using Office 365 and I've dug around in Microsoft 365 Admin Center but can't seem to find a way to do this. Please help! 

(Using Office 365 but the shared drives are still in on-prem servers). GPO within my on-prem domain controller doesn't have any options to create/modify group policies for O365

When opening files on the local network, I get the message "Be careful-files from the Internet can contain viruses...." These files are not on the Internet, they're on the LAN. How can I resolve this without going to each staff member's machine and turning off Protected View or manually adding a "Trusted Location"?

    Hi Jess,

    Office 365 admin center doesn't have Group Policy feature/service. Group Policy is a component only in Windows Server. However you can download Administrative Template files (ADMX/ADML) and Office Customization Tool for Office apps to manage Office settings for users in on-prem DC. After you download the file, please copy & paste the content in "admx" folder to the path in your on-prem DC: C:\Windows\PolicyDefinitions. 

    Then you'll be able to use GPO to configure Office apps settings for all your users. 

    Regards,

    Marvin

    I have over 50 users and was looking for a way to implement this without manually doing this 50 times on each of their machines. Is there a way to push it out via some type of group policy within Office 365 Admin Center?

    Yes, manually add Trusted Locations. I would stick with the top level network location and not a bunch of subfolders. Like make T:\ a Trusted Location, but not T:\Acct, T:\HR, etc. Will be much better from a maintenance standpoint.
