Powershell create account with multiple email addresses

I have this working script but what I would like to do is import multiple emails at the sametime of creating accounts. Is this posssible with what I have. Hypothetically I would have a field from the file I am impoting from with .csv with fields like below

name  alias  userprincipalname  organizationalunit  email addresses
test      test   test                            contoso.local             test1@test.com, test@contoso.local


Import-CSV C:\temp\users.CSV | % {
New-Mailbox -Name $_.Name `
-Alias $_.Alias `
-UserPrincipalName $_.UserPrincipalName `
-OrganizationalUnit $_.OrganizationalUnit `
-Password $pass `
-ResetPasswordOnNextLogon $true
}
