We have a root Domain called A.local and B.local is a sub-tree within the same forest located at another sites.
Recently we setup a Transport Rule via EMC. It controls a group of users (A Universal Dist Group from B.local) ability to send external email. So, Member in this group will be prohibited from sending External Mails.
One of the user being granted external email access and removal from this group via ADUC MMC.
For some reason, EMC still shows the users under the Block External email group and she is still unable to send external emails and there is no option available to remove this user from the group via EMC....
Any idea?
