I just had a question solved regarding outlook clients not connection to exchange because services were not starting up correctly. That problem was solved, but since then i've noticed we haven't been able to send or receive any email at all.
I have tried restarting the transport service. I can telnet the mail domain, no problems there. There are 500+ emails in the queue that I can see in the EMC. I haven't edited any of the connectors and they all look fine.
In the event viewer there are the warnings I have screenied below. Besides this I cannot see any other problem!
