Exchange 2010 SP1 Network Ports Diagram v0.31

It took a while, but I’ve updated the Exchange 2010 SP1 Network Ports diagram I first published in December. Note that the updated version is based on SP1, which you can find in the way to change the address book service for example.

For this version, I’ve included clients, 3rd party SMTP elements, UM and OCS/Lync components and a small list of how to change ports or fix dynamic port settings.

You can download the diagram here. When you got feedback, use the comments or send me an e-mail. Otherwise, feel free the use it; crediting or a reference is appreciated.

Update: Small correction, 135/TPC RPC endpoint mapper from Outlook to Client Access Server was missing (Thanks Maarten).

Update (13Aug11): The Visio can be downloaded through here.

  3. This is very nice. I perform lots of deployments and write several design docs so I will definitely find a place in those docs for this visio. Great stuff and I will make sure I give credit where credit is due (to you). Again, thanks

  6. Nicely formatted mon frere! That looks like it started life as a Visio diagram. Any chance of the Visio for amendments and additions? Yes, I could do it myself from scratch but its a busy week…


    • Hi there

      Yes, it would be great to get our hands on the visio version so re-producing this great doc!

      Any chance we get the Visio file format?



  7. Again awesome work. I was also wondering if i could get the visio version if you have it available. I will still give credit on the doc, but i would need to update to include load balancing.

    Thanks in advance,

  13. very nice technical document, i think we all appreciate the time and effort involved in creating something as detailed as this.


  14. Michel, thanks for putting this together. A few questions.
    I do see port TCP/808 for MRS on this diagram.
    Also, there are a few “Dynamic/TCP” that do not have reference numbers associated, for instance Dynamic/TCP between the CAS and the Mailbox, and Dynamic/TCP between Mailbox and Mailbox. Are those supposed to be reference (3)?
    Do you know if these ports are able to be set to static ports?

  17. According to your diagram 5 ports need to be open between Exch servers and AD DCs.

    Below article talks about opening ports between Exchange servers or Exchange Servers and domain controllers. This article clearly states : Starting with Exchange Server 2007 and current as of Exchange Server 2013, having network devices blocking ports/protocols between Exchange servers within a single organization or between Exchange servers and domain controllers in an organization is not supported. A network device may sit in the communication path between the servers, but a rule allowing “ANY/ANY” port and protocol communication must be in place allowing free communication between Exchange servers as well as between Exchange servers and domain controllers.
