Hello Powershell Experts,

I want to do a proof of concept using Powershell to generate a group membership audit report.  We have a file that has a list of authorized users for the test group.  I then want to compare the list of authorized user to the users actually in the group in Active Directory.  This is easy enough.  I’ve written the following to achieve this goal:

$TargetGroup = "NickTestGroup2"

$AuthorizedGroupMembers = Get-Content -Path C:\PowershellResources\Group2.txt

$GroupMembersInAD = Get-ADGroupMember -Identity $TargetGroup | ForEach-Object {$_.name}

$UnauthorizedGroupMembers = Compare-Object $GroupMembersInAD $AuthorizedGroupMembers -IncludeEqual | Where {$_.sideindicator -eq "<="} | ForEach-Object {$_.Inputobject}

$EmailBody = @"
The following is a list of unauthorized users in the '$TargetGroup':
$UnauthorizedGroupMembers
"@

This almost gives me what I want.  The value of the $EmailBody variable as it is now is:

The following is a list of unauthorized users in the ‘Test Group’:
User1 User2 User3

Ideally, I would like the output to look like:

The following is a list of unauthorized users in the ‘Test Group’:
User1
User2
User3


My question to all of you is:
How can I get my output to is how can I get the content of the $EmailBody variable to list the users on different lines as detailed above?

Try this:
$EmailBody = @"
The following is a list of unauthorized users in the '$TargetGroup':
$($UnauthorizedGroupMembers -join "`r`n")
"@

You change the default string separator $OFS (which is space by default), or join the strings yourself using a different separator.
$EmailBody = @"
The following is a list of unauthorized users in the '$TargetGroup':
$($UnauthorizedGroupMembers -join "`r`n")
"@
