Hi all,
I would like to allow 3rd party cookies only for specific site on Edge browser via GPO.
Can I achieve it using this GPO: User Configuration\Administrative Templates\Microsoft Edge\Content Settings\allow cookies on specific sites and then the name of the site?It will allow the 3rd party cookies also?
Hello @marioandm-7945
Adding the domain/website will allow any cookies from that domain, as explained in the next article:
https://docs.microsoft.com/en-us/deployedge/microsoft-edge-policies#cookiesallowedforurls
However, it is important to check the policy in Administrative Templates>Windows Components>Microsoft Edge>Configure Cookies with value 1.Block only 3rd-party cookies in order to block the rest of 3rd Party cookies, and the previous policy will override for the specific allowed domains/websites
Hope this helps with your query,

hello @LimitlessTechnology-2700
I created that policy cookiesallowedforurls and configure cookies- selected Block only third party cookies.
Third party cookies are blocked by GPO point 1 on screenshot
Cookies allowed for urls - exception appeared point 2 on screenshot
but user can still add some websites (point 3a on screenshot )and I wondering why and how to block this for users.
Also under the website added by user manually appears "including third party cookies on this site".
My questions are. How prevent user from adding sites manually ?
Why "including third party cookies on this site" doesnt appear under site added by GPO. 
screenshot is from my private laptop.Just wanted to explain how it looks on my working environment where I use gpo.
