I was trying to send an email to a person of the same company in a different domain but the message is bouncing back to me. I verified her E-mail addresses tab under user properties in Active directory and she have an entry for X400 type. If I click on "to" when I'm creating a new email and search for the users and the click on advanced|properties|Email addresses tab then the X400 entry is missing. Why this is happenig? Could be a Global address List Sync Issue?
Please Let me know
