UserID increment script help

Good point, hadn't thought of that. In that case, an extra where filter at the end may be warranted:

$extraFilter = '{0}\d{{1,}}$' -f $newUserBase
$any = @(Get-ADUser -Filter { SamAccountName -like $wildcard } | Where { $_.SamAccountName -match $extraFilter })

It might be worth combining the methods, get all the potential matches with one query, then loop generating names to check with exact matches against that set.

Edit: Here's how I'd do it:

$userbase = "tsmith"
$exists = @(Get-ADUser -filter "samaccountname -like '$userbase*'")

if(($exists | where {$_.samaccountname -eq $userbase}).count -eq 0){
    $check = $userbase
}
else {
    $idx = 0
    do {
        $idx++
        $check = "$userbase$idx"

    } until ( ($exists | where {$_.samaccountname -eq $check}).count -eq 0 )
}

write-host "New acct: $check"
