We are having an issue with email routing within our exchange environment which has us looking into ow email is being routed.

We have 2 Exchange 2013 servers which both have the MBX/CAS roles on them.  They use IIS ARR as a reverse proxy on them which was not fully setup for load balancing.

Issue: When one of the exchange servers is down/off all routing of email stops sending and connecting to mailboxes even on databases held on the second server stops.  No access to webmail.  When the server is up and running all mailflow /OWA access works perfectly.

We are trying to distinguish how and why mail is being routed through to the exchnage server which was switched off but no luck as of yet.  

Any advice would be greatly appreciated.  
Thanks in advance
