I created user-disable mailboxes on my AD and i give full control to a group of users
that i want to access that mailboxes. Give to SELF external account associated to be able to disable
the accounts on AD. The users can access the mailboxes with no problems but ....
when they try to send messages from that mailboxes the exchange return the following error: You do not have permission to send to this recipient. For assistance, contact your system administrator.
What is wrong here?? Why my users can send messages from these mailboxes???
