Hello All, I am having a problem giving my CIO's secretary "Send As" permissions to his mailbox. It works fine for mailboxes of users that are not domain admin/enterprise admins. The CIO is a member of the Enterprise Admins group but not domain admins (I don't know why). Anyway, we are on a 2000 Exchange server. When I add her to is acl with send as permissions, it accepts but about 15 minustes to a half hour later, she is automatically removed. (I am assuming because or replication). At his time Enterprise Admins and full access to the servers. Any Ideas?
