smtp creator in excel

$data = $null

$data = @{}

Select-String c:\hash2.txt -Pattern "([a-z]+).+?=.+?([a-z.]+)" |

 ForEach { $_.matches} |

 ForEach { $tokens = @($_.groups[1].value,$_.groups[2].value); $data.Add($tokens[0],$tokens[1])}

 #$data

Import-Csv c:\import1.csv | ForEach `

{

    $_.name.ToLower() -match "^(?<last>[a-z -]+),( (?<middle>[a-z]+))? (?<first>[a-z-]+)( (?<code>[a-z0-9()]+))?$" | Out-Null

    $first = $matches["first"] -replace "[^a-z]","."

    $middle = $matches["middle"] -replace "[^a-z]","."

    $middle2 = $matches["middle"] -replace "[^a-z]","."

    $last = $matches["last"] -replace "[^a-z]","."

    $code = $matches["code"] -replace "[()]"

    $company = $data[$_.company]

    If ($middle)

    { $middle = "." + $middle }

    If ($code)

    { $code = "." + $code }

$newSMTP = "{0}{1}{2}.{3}{4}@{5}" -f $first,$middle,$middle2,$last,$code,$company

#$ADUser = Get-ADUser -identity $_.UserID -Properties Company  

$mbox = Get-Mailbox $_.UserID

$mbox

If ($mbox.PrimarySMTPAddress -ne $newSMTP)

        {

Write-Host  -ForegroundColor Green "Setting primary SMTP $newsmtp address for $mbox "

$newsmtp | out-file -filepath c:\smtp4.csv -append

set-mailbox -identity $_.UserID -PrimarySmtpAddress $newsmtp -EmailAddressPolicyEnabled $false

} else {

Write-Host -ForegroundColor red -backgroundcolor yellow "$mbox has an SMTP-Address already exists in system"

}

    }

hash2.txt looks like that:

"Company1" = 'company1.com'

"company2" = 'company2.com'

"company3" = 'company3.com'

Now the script working as follows:  looking in CSV for company and attach depending on the company the correct mail prefix like @company1.com.

looking in csv for name buidling the name:  firstname.lastname@company.com

What i like to do is to write every build smtp to a special worksheet in excel from row1 up.
