What exactly do you mean by "validate"? If you already have an e-mail
address, how can it be validated? You can validate a name to see if it
resolves to an e-mail address in Outlook. In that case use
Namespace.CreateRecipient and try to resolve it.

Hello;

I am trying to validate a list of email addresses in EXCEL against the
address book in outlook.

Any help would be much appreciated.

Thanks
