Import CVS via powershell Error - Member Already present

Question

Hello,
I've been trying to import some CVS file into exchange with the powershell management console.  I've created a script to import the CVS files below and to ignor the duplicate items:
Import-Csv .\Contacts.csv|
foreach-object {if (Get-MailContact -anr $_.displayname) {write-host $_.displayname 'is a duplicate entry'}
else {New-MailContact -Displayname $_.DisplayName -ExternalEmailAddress $_.EmailAddress -OrganizationalUnit “Contacts” -Alias $_.Alias}
However when I enter the command i just get the following message:
Import-Csv : The member "Dale and Valley Homes" is already present.
At C:\contactimport.ps1:1 char:11
+ Import-Csv <<<< .\Contacts.csv|
+ CategoryInfo : NotSpecified: (:) [Import-Csv], ExtendedTypeSystemException
+ FullyQualifiedErrorId : AlreadyPresentPSMemberInfoInternalCollectionAdd,Microsoft.PowerShell.Commands.ImportCsvC
ommand
I've been looking all over the forums and haven't found a solution to my problem. Any help would be appreciated.
Thanks.

please adjust your cdv with headers and provide them in the import-csv Command
Import-Csv $outFile -Header A,B,C
