The ContentOwner parameter specifies the e-mail address of the person to whom this content belongs. This parameter is necessary for any content that you expect to move to an Exchange server and must match the proxy address of an existing Active Directory user. ContentOwner should be either a valid Notes ProxyAddress or SMTP Address if the ContentOwner is not correct.
