e.g.

Try this and see if it works as expected..
Get-DistributionGroupMember "GroupName" | Get-mailbox | % {
for ($i=$_.EmailAddresses.Count;$i -ge 0; $i--)
{
 if ($_.EmailAddresses[$i].ProxyAddressString  -like “smtp:*” `
	-and $_.EmailAddresses[$i].ProxyAddressString -ne "SMTP:$($_.PrimarySmtpAddress.tostring())")
  {
  Add-Content C:\Group.txt "$($_.EmailAddresses[$i].ProxyAddressString) $($_.PrimarySmtpAddress.ToString())"
  }
 }
}

Hi Subsun

Sorry for my late reply.  The output looks fine with following expections:

1) The lines always begin with smtp:  Would it be possible to get an output without smtp: ?  

2) The script only works if user mailboxes are members of the DL.  But I also have DL's, contacts, public folders which are members of the DL.  Would it be possible to have a script which exports the aliases of these objects as well?

  }
 }

Keep in mind the script will output the recipient which has a different alias address. If a recipient have only primary SMTP address then it wont display in the output (I presume that's what you looking for)

Thank you Subsun, your script works perfectly fine except that it does not read the aliases from public folders.  would that be possible?

SubsunCommented:
It should read aliases from all recipients including public folders. As I mentioned above If a recipient have only primary SMTP address then it wont display in the output. Does your public folder have more than one email address?

Hello Subsun,

You're right, was my mistake.  Our public folders only have 1 email address, the primary SMTP address.

SubsunCommented:
So are we good? or do you want to add those addresses in report?

Check this code and see if the output format is as expected..
Get-DistributionGroupMember "GroupName"  | Get-Recipient | %{
$Primary = $_.PrimarySmtpAddress.ToString()

$_.EmailAddresses | ? {$_.SmtpAddress} | Select -Expandproperty SmtpAddress | % {
	If ($_ -ne $Primary) {
		Add-Content C:\Group.txt "$_ $Primary"
		}
	Else{
		Add-Content C:\Group.txt "$Primary"
		}
	}
}

Or Try this.. Following code will display the email addresses in following format..
If there is only one email address for the recipient then it will write just PrimarySMTPAddress to the file else it will write..
AliasSMTPAddress PrimarySMTPAddress

Get-DistributionGroupMember "GroupName"  | Get-Recipient | %{
$Primary = $_.PrimarySmtpAddress.ToString()
$Email = $_.EmailAddresses | ? {$_.SmtpAddress}
	If (($Email | Measure).Count -gt 1) {
	 $Email | Select -Expandproperty SmtpAddress | % {
		If ($_ -ne $Primary) {
			Add-Content C:\Group.txt "$_ $Primary"
			}
		}
	}
	Else{
		Add-Content C:\Group.txt "$Primary"
	}
}
