The following recipient(s) could not be reached: John Doe on 8/22/2006 10:12 AM You do not have permission to send to this recipient. For assistance, contact your system administrator. MSEXCH:MSExchangeIS:/DC=com/DC=globalknowledge:NC10S252 There is nothing on the recipients configuration that would reject messages from the sender. Both parties are internal employees and both have exchange accounts on the same server and even the same mailbox store. I am perplexed on this one... Thanks for any info.
