How to check if user has an Exchange mailbox

I am writing a script that will perform some functions if the user has an Exchange mailbox. I'm getting stuck on how to check if the user has a mailbox.

Right now I'm using powershell but I can use VBS or batch commands if that's easier.

Here's what I have with powershell:
$strName = "testuser"

$strFilter = "(&(objectCategory=User)(samAccountName=$strName))"
$objSearcher = New-Object System.DirectoryServices.DirectorySearcher
$objSearcher.Filter = $strFilter
$objPath = $objSearcher.FindOne()
$objUser = $objPath.GetDirectoryEntry()

$a = $objUser.msExchMailboxGuid

Open in new window




That works fine to get the mailbox GUID. What I would like to do is compare that $a variable to see if it's empty. But I can't figure out how to run a compare. Here's the value when there is no GUID:

PS C:\> Get-Variable -Name a |fl *

Name        : a
Description :
Value       : {}
Visibility  : Public
Module      :
ModuleName  :
Options     : None
Attributes  : {}

Open in new window


Does anyone have suggestions on how to do this with PowerShell or any other method?

Thanks!

You could try:

Get-User user1 | Select-Object Name,RecipientType,RecipientTypeDetails

you do through query from the active directory users and computer, to show all user with a value in the email address field

$a.Value.Length will be 0 if there's no GUID.

Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

@uescomp I should have given a little more detail. I'm running this command on an RDSH server. So no AD and no Exchange installed on the server so I can't run that command.

@waleeda Sorry but I need this automated in a script

@tgerbert Good suggestion but it's not working for the variable. I seemingly can't evaluate the value. When I run $a.value.length it just returns to the next prompt without giving output. Here's what I get:
PS C:\> $a.value.length
PS C:\>

Open in new window

It's almost like it has a null entry but when I try and compare it to null it just returns to the prompt. If I create the x variable with a null value I get the following:
PS C:\> $x = $null
PS C:\> $x.value.length
PS C:\>

Open in new window


But I can compare it... :
PS C:\> $x -eq $null
True
PS C:\>

Open in new window

but not the empty GUID:
PS C:\> $a -eq $null
PS C:\>

Open in new window

That above command should return either True or False but it is not returning anything. This is why I can't seem to compare it.

OK, I found out what I was missing. The datatype is an Object. I can use one of the object properties to get what I'm looking for. Here's the code:

$strName = "testuser"

$strFilter = "(&(objectCategory=User)(samAccountName=$strName))"
$objSearcher = New-Object System.DirectoryServices.DirectorySearcher
$objSearcher.Filter = $strFilter
$objPath = $objSearcher.FindOne()
$objUser = $objPath.GetDirectoryEntry()

$a = $objUser.msExchMailboxGuid
if($a.count -eq 1)
{write-host User has mailbox}

Open in new window
