Although nothing wrong with the answer, I've tried to get into the habit of only returning properties I want to use as when working with bigger sets of data is can speed things up a little. In this case maybe go with:

Get-ADUser -Filter "EmployeeID -eq 12345" -Properties EmployeeID,DisplayName,Title,userprincipalname | select -property EmployeeID,DisplayName,Title,userprincipalname

Won't make a lot of difference to this command however if learning powershell, its something I wish I was aware of initially as it would have made a lot of AD related scripting a lot faster had I known. In a quick test in my environment, specifying properties * took 450ms where as specifying just the ones I intended to use was 60ms

It will make a big difference if an actual AD object was expected instead of a PSCustomObject.

There's no need to ask for ALL the properties of an AD object. Just specify the ones you need that aren't returned by default. How long does it take to do only this: Get-ADUser -Filter "EmployeeID -eq 12345" -Properties EmployeeID,DisplayName,Title,userprincipalname

From the Get-ADUser help:

Outputs
ADUser

Returns one or more user objects.

This cmdlet returns a default set of ADUser property values. To retrieve additional ADUser properties, use the Properties parameter.

To get a list of the default set of properties of an ADUser object, use the following command:

Get-ADUser<user>| Get-Member

To get a list of the most commonly used properties of an ADUser object, use the following command:

Get-ADUser<user>-Properties Extended | Get-Member

To get a list of all the properties of an ADUser object, use the following command:

Get-ADUser<user>-Properties * | Get-Member

Hello there,

Here's one quick way:

([ADSISearcher] "(sAMAccountName=kendyer)").FindOne()
If it returns no results, the user account was not found.

As a function:

function Test-ADUser {
param(
[Parameter(Mandatory = $true)]
[String] $sAMAccountName
)
$null -ne ([ADSISearcher] "(sAMAccountName=$sAMAccountName)").FindOne()
}
