MAPI 7830

Arafat Rahman


We use customized MAPI port which is 24577. After adding RB steelhead in domain, we are seeing optimization on 24577. But still can see a lot of traffic going without optimization on 7830 (MAPI) port. 


Whats the go with that? Is there way to optimize it? According to RB doco, 7830 is used by RiOS.

    sounds like you are using outlook 2007 with encryption turned on. Are you seeing red waring traingles for each 7830 current connection? first , uncheck encryption support within the outlook 2007 client and see if this provides optimizations for 7830?

    the steelhead can support outlook 2007 encryption if configured in the right manner.

    The documentation I find, including KB 1930, show 7830 as a MAPI Exchange port.  Also, the port labels show a gap in the Riverbed port between 7820 & 7850: 7744, 7800-7801, 7810, 7820, 7850, 7860, 7870.


    KB 1930:

    The Steelhead appliance and RiOS use the following TCP ports:


    <span>Port </span>




    Data store sync port 


    In-path port 


    Out-of-path port 


    Failover port 


    MAPI Exchange port 


    NSPI port


    Connection forwarding (neighbor) port


    Interceptor appliance
