While troubleshooting another issue with one of three exchange servers, SMTP protocol was reinstalled by a domain admin (although not Exchange Admin). Since this happened no email leaves the Outbox on the clients, the Local Delivery Queue says ready but always has 0 messages.
Incoming mail to mailboxes on this server get a bounce back saying it cannot find the mailbox.
We have 2 other exchange servers (1 of which has other problems) that are not seeing this behavior.
