Can't send or receive on new exchange 2010 server
Posted on 2013-06-11
I have a 2003 exchange server, a 2007 server and a 2010 server.
The 2003 server sends and receives all mail out of the organisation
It goes to Symantec cloud filter first.
There are no mailboxes on the 2003 server. It is legacy. I am not sure why (I am still new to the organisation)
The 2007 server currently holds the site’s mailboxes. It sends outbound mail through the 2003 server using inbound and outbound hub transport connectors.
They are easy to find and I can see their configuration.
We have a plan to upgrade to 2010. Our plan has been to create a new 2010 server. (all three servers are physical)
The 2003 server I have built as per Microsoft instructions and all tests have been successful till now.
I have migrated an old user’s mailbox across to the new server. I have also created a new user on the new server.
I have used the same settings in the 2010 server as were configured for the 2007 server.
I can open the mailbox via owa and see mail that was already there.
I can’t send and receive from it. When I go to send from it I get: #550 4.4.7 QUEUE.Expired; message expired ##
Outbound email sits in the queue indefinitely.
When I say send or receive, I mean I can’t send to users inside the organisation on the 2007 mail server, and they can’t send to the 2010 one.
Also externally I can’t send to the 2010 and the 2010 users can’t send externally either.
I can logon via OWA to the mailboxes on the server, I can move mailboxes to the server, the other exchange servers have this server in their heirachy in ESM.
I have removed the connectors and recreated them.
I have restarted the server.
Any ideas ?
Thanks for your help in advance.
