Cant return string for msExchMailboxGUID

Question

_{Monday, May 26, 2014 1:08 AM}

Hi All,

I am trying to get users msExchMailboxGUID as a string using the function below, however the msExchMailboxGUID is being returned as System.Byte[]. Any idea how to get this to display as a string?

Function Get-ADProps {
               
                                $root = [ADSI]"LDAP://*******"
                                $people = Import-Csv .\users.csv
                                $searcher = new-object System.DirectoryServices.DirectorySearcher($root)      
                               
                $ADObjects = @()
                                ForEach($person in $people){
                               
                                                                $ADuser = $person.InternetAddress
                                                                $searcher.filter = "(&(objectClass=user)(mail=$ADUser))"
                                                                $users = $searcher.FindAll()
                                                               
                                Foreach($user in $users)
                                {
                                                                [Array]$propertiesList = $user.Properties.PropertyNames
                                                                $obj = New-Object PSObject
                                
                                               
                                                                Foreach($property in $propertiesList)
                                                                {
                                                                                $obj | add-member -membertype noteproperty -name $property -value ([string]$user.Properties.Item($property))
                                                                }

                                                                $ADObjects += $obj
                                                }
               
                }
                Return $ADObjects
}

Get-ADProps | Select msExchMailboxGUID, SAMaccountName

Joe, point 1 is very straight forward approach.You can try something like this

$pro = Get-ADUser -Identity 'TestAD' -Properties *
$string = $pro.msExchMailboxGuid
$bytes = [System.Text.Encoding]::Unicode.GetBytes($string)
[System.Text.Encoding]::ASCII.GetString($bytes)

Chen,  you method works too.  However I always hold the opinion that one should always use Exchange to do anything related to Exchange:

Import-Csv .\users.csv | select -ExpandProperty 'InternetAddress' | Get-Mailbox | select 'ExchangeGuid', 'SamAccountName'

The above one liner does the same job as the code in the OP, in readable format.

Mike,

Two things you should consider:

1. Use Exchange Management Shell, which will give you the mailbox GUID in a more printable format.
2. Use System.Guid, which is very straight forward.

Cheers.

I agree with you Joe,  Indeed one liner of yours does the same. I also want OP to use exchange method of doing. But, I thought of sharing Windows PowerShell quick way of doing.

Cheers :)

Hi,

yes thanks, Chen's reply was correct. I was not able to use exchange cmdlets in this instance so AD was the only option for me. Thanks for the reply Chen.
