Hi,
i am currently deploying a new exchange 2013 solution. I already deployed 2 CAS and 2 Mailbox Servers. There is currently no DAG configured. I'm just testing mail flow and i noticed that inbound mail is somehow deferred.
I just had a look into Queue Viewer and saw a lot of strange objects there...

Sender Address is always HealthMailbox* or inboudproxy@inboundproxy.com...
Some Idea why those mails are stuck in the queue?
