DirSync “Busted Users” Report

If you administer DirSync for your organization, you likely have seen emails like this, indicating some of your users didn’t sync.

DirSync Error Email

It can be a frustrating email, since the “error description” is for some reason blank and the “On-premises object ID” column is not something that’s easy to correlate to a user account within your Active Directory. There are also application event log entries (FIMSynchronizationService #6111 and Directory Synchronization #0), but again these aren’t exactly rich with detail.

Many of you know that DirSync is actually a customized installation FIM 2010 R2’s Synchronization Service. Within the miisclient.exe console, you can look at your most recent “Export” job and examine the errors one at a time.

Miisclient.exe Console


(By the way, this is actually the place to go if you wanted to configure filtering for directory synchronization.)

Using this console certainly works, but it’s not an efficient way to resolve errors. Microsoft seems to acknowledge this, but falls short of a fix with that email, in my opinion. Instead of wearing out your mouse, I propose you use the PowerShell script I have written below. Within, I leverage the free FimSyncPowerShellModule which you’ll need to download and copy to:

…\System32\WindowsPowerShell\v1.0\Modules\FimSyncPowerShellModule\FimSyncPowerShellModule.psm1

Once you’ve copied the module, you’re ready to run the report, which can be downloaded here.

Here is a sample output, followed by the code itself.

DirSync Report

Azure Active Directory Sync (DirSync) seems so simple on the surface doesn’t it?  “Next, Next, Finish”, right?  Ha!  If you’ve ever had to revisit your DirSync server to troubleshoot or make a configuration change, you know there can be more than meets the eye.  A lot of useful information happens to be scattered across various registry keys, SQL tables and XML files.  If you’re not familiar with the FIM Management Console, and these other locations it might be hard to see what’s going on.

Here’s a free script that aims to help by creating a dashboard highlighting useful DirSync configurations.  See the image below for a sample output.  Before you run it you should be aware of the limitations listed in the “known issues” area of the script.

Oct 2014 Update: Fellow MVP, Michael Van Horenbeeck has written an update to this script for use with the new Azure AD Sync Tool.  Please be sure to check it out here: http://vanhybrid.com/2014/10/26/azure-ad-sync-tool-html-report/

DirSync Report

Known Issues:
1) All commands, including SQL queries run as the local user.  This may cause issues on locked-down SQL deployments.
2) For remote SQL installations, the SQL PowerShell module must be installed on the dirsync server.
    (http://technet.microsoft.com/en-us/library/hh231683.aspx)
3) The Azure Service account field is actually just the last account to use the Sign In Assistant.
    There are multiple entries at that registry location.  We're just taking the last one.
4) Assumes Dirsync version 6385.0012 or later.

Converting SMTP Proxy Addresses to Lowercase

Update: Be aware, this script has not been tested with SIP, X400 or other address types. I am working on an update to validate these scenarios, but in the meantime, proceed at your own risk with these address types.

I recently encountered a question in an online forum where someone asked for a script to convert all of their user’s email addresses to lower case values.  While this doesn’t affect the message delivery, it can have an impact on aesthetics when the address is displayed in an external recipient’s email client.  An Exchange Email Address Policy can do this to some degree, but I wanted to see how it could be done with PowerShell.

The challenge with a script like this is twofold:

  1. Email addresses (proxy addresses) are a multi-valued attribute, which can be tricky to work with.
  2. PowerShell is generally not case-sensitive, and therefore when we try to rename Mr. Gallalee’s email address in the screenshot below, we can see that it does not work:

WARNING: The command completed successfully but no settings of 'demolab.local/Users/Rob Gallalee' have been modified.

After a little bit of inspiration from a script written by Michael B Smith, I came up with the below:


$MailboxList = Get-Mailbox  -ResultSize unlimited

$MailboxList | % {

$LoweredList = @()
$RenamedList = @()

foreach ($Address in $_.EmailAddresses){
if ($Address.prefixstring -eq "SMTP"){
$RenamedList += $Address.smtpaddress + "TempRename"
$LoweredList += $Address.smtpaddress.ToLower()
}
}
Set-mailbox $_ -emailaddresses $RenamedList -EmailAddressPolicyEnabled $false
Set-mailbox $_ -emailaddresses $LoweredList

#Without this line the "Reply To" Address could be lost on recipients with more than one proxy address:
Set-mailbox $_ -PrimarySmtpAddress $_.PrimarySmtpAddress
}

This script works as follows:

  1. Puts all mailboxes into the $MailboxList variable.  If you don’t want all mailboxes,  edit the Get-Mailbox cmdlet as you see fit.
  2. Filters out X400 and other non-SMTP addresses.
  3. Creates an array called $RenamedList which stores each proxy address with “TempRename” appended to it (e.g. Rgallalee@demolab.localTempRename).
  4. Creates another array ($LoweredList) and use the “ToLower” method on each proxy address.
  5. Sets the proxy address for the user to the value of $RenamedList and then to $LoweredList.
    1. This is how we get around the case case insensitivity – name it to something else and then name it back.
  6. Step 4 and 5 don’t preserve the “Primary” / “Reply-To” address, so we set it back manually with the last line.

Note: This script turns off the email address policy for each user.

As always, feedback is welcome.

EDIT Dec 2018:
This is a similar approach, but for mailboxes migrated to Office 365. In this case, only the Primary SMTP addresses are targeted.

It may also be faster than the above, due to the fact we’re only operating against mailboxes that have uppercase (vs all of them).

Set-ADServerSettings -ViewEntireForest:$true

$TargetObjects = Get-RemoteMailbox -ResultSize Unlimited | Where {$_.PrimarySmtpAddress.ToLower() -cne $_.PrimarySmtpAddress}

Write-Host $TargetObjects.count "Remote mailboxes have one or more uppercase characters." -ForegroundColor Cyan

#Backup First
Function Get-FileFriendlyDate {Get-Date -format ddMMMyyyy_HHmm.s}
$DesktopPath = ([Environment]::GetFolderPath("Desktop") + '\')
$LogPath = ($DesktopPath + (Get-FileFriendlyDate) + "-UppercaseBackup.xml")

$TargetObjects | select DistinguishedName, PrimarySMTPAddress, EmailAddresses | Export-Clixml $LogPath
Write-Host "A backup XML has been placed here:" $LogPath -ForegroundColor Cyan
Write-Host

$Counter = $TargetObjects.Count

foreach ($RemoteMailbox in $TargetObjects) {

    Write-Host "Setting: " -ForegroundColor DarkCyan -NoNewline
    Write-Host $RemoteMailbox.PrimarySmtpAddress -ForegroundColor Cyan
    Write-Host "Remaining: " -ForegroundColor DarkCyan -NoNewline
    Write-Host $Counter -ForegroundColor Cyan

    Set-RemoteMailbox $RemoteMailbox.Identity -PrimarySmtpAddress ("TMP-Rename-" + $RemoteMailbox.PrimarySmtpAddress) -EmailAddressPolicyEnabled $false
    Set-RemoteMailbox $RemoteMailbox.Identity -EmailAddresses @{remove = $RemoteMailbox.PrimarySmtpAddress}

    Set-RemoteMailbox $RemoteMailbox.Identity -PrimarySmtpAddress $RemoteMailbox.PrimarySmtpAddress.ToLower()
    Set-RemoteMailbox $RemoteMailbox.Identity -EmailAddresses @{remove = ("TMP-Rename-" + $RemoteMailbox.PrimarySmtpAddress)}

    $Counter --
}

Write-Host
Write-Host "Done." -ForegroundColor DarkCyan

#End

 

Combining PowerShell Cmdlet Results

In my last post I used used New-Object to create an desirable output when the “Get-Mailbox” cmdlet didn’t meet my needs.  If your eyes glazed over trying to read the script, let me make it a bit simpler by focusing on a straight forward example.

Say you need to create a list of user’s mailbox size with their email address.  This sounds like a simple request, but what you’d soon find is that mailbox sizes are returned with the Get-MailboxStatistics cmdlet and the email address is not.  For that, you need to use another cmdlet, such as Get-Mailbox.

With the New-Object cmdlet, we are able to make a custom output that contains data from essentially wherever we want.

See this example:

$MyObject = New-Object PSObject -Property @{
EmailAddress = $null
MailboxSize = $null
}

In this example, I have created a new object with 2 fields, and saved it as the $MyObject variable.

For now, we’ve set the data to null, as shown below:

$MyObject

The next step is to populate each of those fields.  We can write to them one at a time with lines like this:

$MyObject.EmailAddress = (Get-Mailbox mcrowley).PrimarySmtpAddress
$MyObject.MailboxSize = (Get-MailboxStatistics mcrowley).TotalItemSize

Note: The variable we want to populate is on the left, with what we want to put in it on the right.

To confirm our results, we can simply type the variable name at the prompt:

$MyObject with data

Pretty cool, huh?

Ok, so now about that list.  My example only shows the data for mcrowley, and you probably need more than just 1 item in your report, right?

For this, you need to use the foreach loop.  You can read more about foreach here, but the actual code for our list is as follows:

(I am actually going to skip the $null attribute step here)

$UserList = Get-mailbox -Resultsize unlimited
$MasterList = @()
foreach ($User in $UserList) {
$MyObject = New-Object PSObject -Property @{
EmailAddress = (Get-Mailbox $User).PrimarySmtpAddress
MailboxSize = (Get-MailboxStatistics $User).TotalItemSize
}
$MasterList += $MyObject
}
$MasterList

$MasterList with data

Finally, if you wanted to make this run faster, we really don’t need to run “get-mailbox” twice.  For better results, replace the line:

EmailAddress = (Get-Mailbox $User).PrimarySmtpAddress

With this one:

EmailAddress = $User.PrimarySmtpAddress

Dealing with PST Files

Chances are, if you read my site, you also read the Exchange team blog.  This means you’ve seen the PST Capture Tool!  I’ve had a chance to work with this tool for a little while now and have found it to be a delight!PST File

“PSTs are bad M’kay?“

This is a line we’ve all recited a time or two (ok maybe not exactly that line), but do we even know why?  Are we just parrots, or do we actually have a reason for condemning this hugely prolific file format?

Let’s start by acknowledging that PST files aren’t all bad.  M’kay?  If you run Outlook at home, or if you use IMAP/POP-based accounts (Gmail, Hotmail, etc) at work, using a PST file can actually be a good idea.  While it is possible to direct internet mail to the Exchange mailbox, this would create several problems:

    • Wasting expensive Exchange disk space
    • Potential violation of company policies
    • Internet mail is now subject to corporate retention (and discovery!) policies
    • Makes moving to a job more painful
    • etc.

AutoArchive Group Policy Settings

I’d even go so far as to say you might want to use PST files for archiving corporate email!  If you run a small shop – or a big one that isn’t subject to any retention policies.  A group policy configuring AutoArchive (and a note to your users) might be a good way to implement spring cleaning in your Exchange data stores.

See, PST files actually can serve a purpose!

Then there is the other side of the coin:

In most situations, PST files represent unmanaged storage of email.  For someone who is charged with administering an email environment, this means we aren’t able to do our job.  If users begin to rely on something that we aren’t taking care of; what happens when it breaks?  We’ve all had the uncomfortable task of telling someone we can’t get their data back at least once in our careers.  It doesn’t make for fun times.

More important than our comfort; many organizations are subject to regulations which require them to turn email data over to the courts upon request.  A judge wont want to hear your sob story about how PST files aren’t searchable, and how you’re going to have to look across the whole network by hand to find that email thread.

I recently completed an Exchange 2010 deployment for a government organization that was subject to such legislation.  Once we activated the Personal Archive for their users, they decided to put the kibosh on PST files.  To enforce this, we laid out a three phased approach:

  1. Prevent the users from making new PST files
  2. Prevent the users from adding content to existing PST files
  3. Use the abovementioned PST Capture Tool to import PSTs as necessary

The first two steps were quite simple to accomplish.  Outlook reads a registry value called PSTDisableGrow (REG_DWORD).  We deployed a GPO to implement this as follows:

Outlook 2003 HKCU\Software\Microsoft\Office\11.0\Outlook\PST\
Outlook 2007 HKCU\Software\Microsoft\Office\12.0\Outlook\PST\
Outlook 2010 HKCU\Software\Microsoft\Office\14.0\Outlook\PST\

Set PSTDisableGrow to “1” (without the quotes).  This will allow users to mount PST files in Outlook, but it will not allow any new content to be placed within.  Don’t worry about overkill here.  I used a single GPO for all 3 settings.  Outlook version X doesn’t care about extra registry settings in Outlook Y’s key.

PSTDisableGrow has some siblings; read more about DisablePST, DisableCrossAccountCopy and DisableCopyToFileSystem here.

That’s all for now, have a great week!
