exchange power-shell script to email distribution list owners - powershell

Question

I am having a bit of a tough time writing a script for exchange. I have an environment, that has a hybird environment. I am trying to make a power shell script to find all large distro groups and email the owners of the groups to clean them up. However, I am having issues with pulling the owner email and and name for the email portion of the script.
But, there are a few restrictions, I can't use AD powershell, exchange only. and I can't use the get-mailbox cmdlet.

set the scope of the search
Set-ADServerSettings -ViewEntireForest $true
$DistGroups = Get-DistributionGroup -ResultSize 2
ForEach ($Group in $DistGroups) {
#Get each group details
$MemberCount = (Get-DistributionGroupMember $Group).count
$GroupName = (Get-DistributionGroup $Group).DisplayName
$Owner = (Get-DistributionGroup $Group).ManagedBy
$OwnerEmail = Get-recipient -identity $Owner | select PrimarySmtpAddress
$OwnerFN = Get-Recipient -identity $Owner | Select FirstName
If ( $MemberCount > 50000) {
#define email stuff
$messageBody = "Hi, <b>$OwnerFN,</b><p>"
$messageBody += "We are auditing distribution groups in our environment and your group, $GroupName, was flagged as being
<font color=red>really large</font>. The current member count is <font color=red> $MemberCount</font>.<p>"
$messageBody += "Please take steps to update the group and clear out unnecessary or old group members… <p>"
$messageBody += "Thanks, <p>"
$messageBody += "The Exchange Admin Team"
#Send the mail
$email = New-Object System.Net.Mail.MailMessage
$email.From = "Email_Group_Admin_Report#Internal.Mail.company.com"
$email.To.Add("me#company.com")
#$email.To.Add("$OwnerEmail")
#$email.CC.Add("#company.com")
#$email.BCC.Add("admin#company.com")
$email.DeliveryNotificationOptions = [System.Net.Mail.DeliveryNotificationOptions]::OnSuccess
$email.IsBodyHtml = $True
$email.Priority = [System.Net.Mail.MailPriority]::High
$email.Subject = "Distribution Group Audit"
$email.Body = $messageBody | Out-String
$smtp = New-Object System.Net.Mail.SmtpClient
$smtp.Host = "mail.compnany.com"
$smtp.Send($email)
}
}
I am able to get the count, and the Distro name, I can't seem to get the managed by property or the other stuff, it spits out an entire list of primary emails and Firstnames and such... The managed by property doesn't seem to appear....

Answer 1

$OwnerEmail = Get-recipient -identity $Owner | select PrimarySmtpAddress
This will return an object, but when you send the email you're acting as if you have a string.
email.To.Add("$OwnerEmail")
Option A:
($OwnerEmail = Get-recipient -identity $Owner).PrimarySmtpAddress
email.To.Add($OwnerEmail)
Option B:
$OwnerEmail = Get-recipient -identity $Owner | select PrimarySmtpAddress
email.To.Add($OwnerEmail.PrimarySmtpAddress)

Answer 2

I had a tough time with the output formats, but I finally got it working as expected. Thought I would post the working script here... Maybe you will find it useful.
add-pssnapin microsoft.exchange.management.powershell.e2010
# Find all Distros
$DistGroups = Get-DistributionGroup -ResultSize unlimited
ForEach ($Group in $DistGroups) {
#Get each group details
if ($Group.managedby -ne $null) {
$t = $Group.Managedby
$t | foreach { $Owner = $_.Name }
}
else {
$Owner = "Unknown"
$DL_Name = $Group.displayname
}
$MemberCount = (Get-DistributionGroupMember $Group).count
if ($Owner -eq "Unknown") { echo "The owner is unknown!"
}
#set membercount catch here
elseIf ( $MemberCount -gt 2000) {
$OwnerEm = get-recipient $Owner | select PrimarySmtpAddress | ft -HideTableHeaders | out-string
#$OwnerEm = get-recipient me#company.com | select PrimarySmtpAddress | ft -HideTableHeaders | out-string
#define email stuff
$messageBody = "Hi, <b>$Owner,</b><p>"
$messageBody += "We are auditing distribution groups in our environment and your group, $DL_Name, was flagged as being <font color=red>really large</font>. The current member count is <font color=red> $MemberCount</font>.<p>"
$messageBody += "Please take steps to update the group and clear out unnecessary or old group members… <p>"
$messageBody += "Thanks, <p>"
$messageBody += "The Exchange Admin Team"
#Send the mail
$email = New-Object System.Net.Mail.MailMessage
$email.From = "Email_Group_Admin_Report#Internal.Mail.company.com"
#$email.To.Add("me#company.com")
$email.To.Add("$OwnerEm")
#$email.CC.Add("#company.com")
#$email.BCC.Add("admin#company.com")
$email.DeliveryNotificationOptions = [System.Net.Mail.DeliveryNotificationOptions]::OnSuccess
$email.IsBodyHtml = $True
$email.Priority = [System.Net.Mail.MailPriority]::High
#$attachment = "C:\myfile.txt"
#$email.Attachments.Add( $attachment )
$email.Subject = "Distribution Group Audit"
$email.Body = $messageBody | Out-String
$smtp = New-Object System.Net.Mail.SmtpClient
$smtp.Host = "mail.company.com"
$smtp.Send($email)
echo "the $DL_Name has a high member count. The member count is $MemberCount. The manager has been sent and email at $OwnerEm"
}
else {
echo "the $DL_Name seems fine! The member count is $MemberCount. The manager '$Owner' is doing great!"
}
}
I left the echo statements in so you can view the statuses via a console, or pipe them to a file.... or something...
