Good morning!

I'm very new to Powershell scripting so please give me your utmost support whenever possible. Thank you in advance.

Scenario
I have been trying to work on a condition based on the result of Get-ADUser -Identity <Input>. Whenever I use that statement for an none existence user account, it will always be the default error message. I need to have it return a certain value be it True/False, 1/0 or anything else so that I can use the result from that statement to perform my task.

Can anyone please advise?

Thank you once again and best regards.
Ronald

    Wrap the cmdlet in a Try/Catch: 

    Try{
    Get-ADUser -Identity xxxxx -ErrorAction STOP
    # code goes here for a successful execution
}
Catch{
    # code goes here for a failed attempt
}

    Hi,
    besides what @Rich Matheisen suggested you can always do the following: 

    if ( Get-ADUser -Identity <Input>) {  
 #True (1)  
 } else {  
#False (0)  
}

    although I find the try and catch approach better.
