  • The diagram makes it look like that, yes. But that is an old diagram, and after RPC exploits appeared, FE in DMZ is not as popular as it once was. FE-BE communication requires some vulnerable ports to be open, otherwise the FE can't function properly as a domain member. I think it is now best to just have the FE within the LAN, and use it primarily as a protocol proxy. The only reason I linked to the diagram was to show how the servers responded to different protocols, rather than a suggestion for a practical topology.

  • A front end server can only act as a proxy to mailbox data held on back end servers. One particular limitation is that you can't practically have mailboxes on the FE server. If you have mailboxes on an FE server (and the System Manager will not actually prevent you from doing this), then they will not be accessible by any type of client. They don't get broken, or anything like that. You just can't access them until you move them to a BE server.

  • BTW - this is the Exchange 2013 forum.

    You should take this to the 2003 one :)

  • Yes, there are a lot of questions about anything BUT Exchange 2013 in the Exchange 2013 forums - it doesn't look like everyone reads the forum title to see if it is pertinent before posting.

    Please mark as helpful if you find my contribution useful or as an answer if it does answer your question. That will encourage me - and others - to take time out to help you.

  • Yeah,  for Exchange 2003 I can understand.

    Not so much for Exchange 2007.  They have no excuse :)

  • There was Exch2010 server forum in the past.

    But I could only find Exch2013 forum now.

  • From the LAN, I think MAPI goes direct to the BE mailbox server that the mailbox is on. From the WAN, MAPI should be coming in via RPC over HTTP (Outlook Anywhere), and will be proxied via the FE server. There is a nice diagram here:
