Powershell – How to set msExchMailboxGUID using powershell or any other method

active-directoryexchange-2010powershell

I need to set the msExchMailboxGUID for many accounts in bulk. My input for this data comes from the Powershell command Get-MailboxStatistics. In it is an object that has the GUID for the mailbox.

I need to save that GUID into AD, so this is what I'm doing to GET the object:

   $thisDN = $oneUser.DistinguishedName
   $user = [ADSI]"LDAP://$thisDN"  

  try 
  {
     $user.get("msExchMailboxGUID")
  }
  catch
  {
      $desc = ""
  }

What is the correct way to Set the object?

I'm unable to use "set" or "put" to upload and save the error. It would even be better if someone can point me to detailed object details since I'm not sure where to look for details on something that is instantiated with the [ADSI] brackety thing.

If this is just using the COM ADSI objects, then what is the correct syntax for "put"? I've tried parentheses, commas, and am unable to get Powershell to talk COM.

Continuing from your example, this would work:

$guid = $user.get("msExchMailboxGUID")

$thisDN2 = $twoUser.DistinguishedName
$user2 = [ADSI]"LDAP://$thisDN2"

$user2.put('msExchMailboxGUID', @($guid))
$user2.setinfo()

Powershell – How to register a DLL using PowerShell without RegAsm

Not sure, but your trouble seems to come from a side effect of UAC Virtualisation (this article can also help) which exists from Vista and is still valid here. An abstrat is that system parts of the file system and registry are now protected from user access, but to assume that old (32 bits) programs continue working the system make them believe they write on these parts, but in fact he redirect them to user's places. Have a look in "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node" in your registry.

A trouble I encounter recently is that my MSI was built with a 32 bits librarie, so invoking these libraries during installation on a 64 bits machine make UAC virtualisation install my registry keys in Wow6432Node. This Internet article helps me to solve the problem. I use Orca to replace Installutillib.dll from 32 to 64 bits.

Powershell 2: How to find arbitrary object in AD having a specific email address

Note that the "mail" attribute is not the only place where an email address may be located. There is also a multi-valued attribute "proxyAddresses", where additional email addresses may be assigned to an object.

Someone has created a script here: (requires the free Quest AD cmdlet)

http://poshcode.org/1594

    Param (
    [Parameter(Mandatory=$true,
        Position=0,
        ValueFromPipeline=$true,
        HelpMessage="Enter SMTP address to search for in Active-Directory."
    )]
    [string]$objSMTP
    )
Function Get-ProxyAddresses ([string]$Address){
$objAD = $null
$objAD = Get-QADObject -LdapFilter "(proxyAddresses=*$Address*)" -IncludeAllProperties -SizeLimit 0 -ErrorAction SilentlyContinue
Write-Output $objAD
}#Close Function
#Validate Quest PSSnapin is loaded
Add-PSSnapin -Name Quest.ActiveRoles.ADManagement -ErrorAction SilentlyContinue
#Run Function to search AD for SMTP address
$Results = $null
$Results = Get-ProxyAddresses -Address $objSMTP | Select-Object Name,DisplayName,ObjectClass,Email,AccountisDisabled,AccountisLockedOut,MailNickName,LegacyExchangeDN -ErrorAction SilentlyContinue
IF($Results -eq $null){
Write-Host ""
Write-Host "No Object Found with .attribute[proxyAddress] containing $objSMTP."}
Else{$Results | Format-List *}
#End
