My SharePoint domain is contoso.com, and we have another domain called contoso2.com. We want the users from contoso2.com to be resolved when we use People Picker column in SharePoint site, for example, when I type one user from contoso2.com in a people picker column, it will save the value successfully. Is it possible? If yes, how to do that? Any suggestion is appreciated.

    Hi @Andy ,
    You want to enter users from another domain in the list person column.
    1.You need to first establish a trust relationship between the two domains. Then Configure People Picker in SharePoint 2019.

    2.Then run the following command for each of your web applications, substituting the example URL and domains with your web application URL, local and trusted domain and/or forest.For a full forest trust:

    stsadm -o setproperty -pn peoplepicker-searchadforests -pv "forest:MY-DOMAIN.local;forest:TRUSTED-DOMAIN.local;domain:MY-DOMAIN.local;domain:TRUSTED-DOMAIN.local" -url http://my-sp-site.com.au/  
    

    You should now be able to add users from both sides of the trust to your Sharepoint list.
