Check if a file exists or not in Windows PowerShell?

Just to offer the alternative to the Test-Path cmdlet (since nobody mentioned it):

[System.IO.File]::Exists($path)

Does (almost) the same thing as

Test-Path $path -PathType Leaf

except no support for wildcard characters

Use Test-Path:

if (!(Test-Path $exactadminfile) -and !(Test-Path $userfile)) {
  Write-Warning "$userFile absent from both locations"
}

Placing the above code in your ForEach loop should do what you want
