Find user without mailbox

[Jesper Stein]

Hi. Im trying to create a script that loads users from an AD Group and filter them based on an attribute. My goal is to have a script that loads users from a group, finde the ones that do not have a mailbox in my exchange inviroment, and mail enable them.

Right now im stuck on the "finde the users".

My Scirpt so far:

#----------------------------------------------------------
# LOAD AD MODULES
#----------------------------------------------------------
Import-Module ActiveDirectory -ErrorAction Stop

#----------------------------------------------------------
# IMPORT  MEMBERS OF GROUP
#----------------------------------------------------------
$Users = Get-ADGroupMember -Identity "S_Enable_Exch2010User"
$Users | ForEach{Get-ADUser -filter {-not(msExchMailboxGuid -like "*")}}

How ever, this looks at all users in my AD and not the ones in $Users.

What am I doing wrong....????

I dont have access to AD right now, but i think you could do something like this. ! in front of $user.msExchMailboxGuid means that if the variable is null(empty), it should create a mailbox, if its already have a mailbox, a message stating this is dispalyed. Hope this works, or sett you on the right track.

$Users = Get-ADGroupMember -Identity "S_Enable_Exch2010User" | Get-ADUser -filter {msExchMailboxGuid -like "*"}

foreach ($user in $users) {

if(!$user.msExchMailboxGuid) {
    enable mailbox command
}
else {
    $user.firstname+"already have a email account."
}
}

Why don't you simply use the Exchange cmdlets for that? Get-Mailbox or Get-Recipient will do the tasks with ease.

And to answer the specific question about the cmdlet - you are not referencing the $users value in any way or form, thus the cmdlet runs against the whole of AD. Add it to the filter.

Yes, if you don't pipe $_ in ForEach statement then you will get All Users. Try this instead (replace 'mydomain.com' with your desired domain, and samaccountname with the property you want):

$Users = Get-ADGroupMember -Identity "S_Enable_Exch2010User"

ForEach ($User in $Users) {

If !($_.msExchMailboxGuid) { 

    Set-ADUser -Identity $User -EmailAddress ($_.samaccountname + '@mydomain.com')

    }
