First  As it currently stands  the  User variable does not have a  Users property  In your code   User simply represents one line  the  current  line in the foreach loop  from the text file    getmembership   Get-ADUser  User -Properties MemberOf   Select -ExpandProperty memberof   Secondly  I do not believe you can query an entire forest with one command  You will have to break it down into smaller chunks    Query forest for list of domains Call Get-ADUser for each domain  you may have to specify alternate credentials via the -Credential parameter   Thirdly  to get a list of groups that a user is a member of    User   Get-ADUser -Identity trevor -Properties     GroupMembership     user memberof        Get-ADGroup     Name     -join         Result  Orchestrator Users Group ConfigMgr Administrators Service Manager Admins Domain Admins Schema Admins   Fourthly  To get the final  desired string format  simply add the  User Name  a semicolon  and the  GroupMembership string together    User SamAccountName          GroupMembership
