  • MsExchange RBAC EventID 16, about permissions


    I just set up two Exchange Servers (2010 SP3)

    When I try to load the Management console, I receive this message: "The Operation couldn't be performed because domain\Administrator couldn't be found."

    I looked into the event viewer and saw this: "MsExchange RBAC EventID 16"

    With a search engine, I find some people having the same issue, and the recommendation is to look for the group "Organization Management" within "Microsoft Exchange Security Groups" , and in this group the user "Administrator" must reside.

    It is the case in my implementation.

    There are no firewalls involved. I restarted the Domain controller twice at least and the two Exchange servers.

    I found this:

    "... Is the SID same on your DC1 and Exchange Server?
    If so, I suggest you reinstall Exchange Server on another server (with different SID) to have a try.

    This happens to me. I cloned two virtual machines and I din NOT know the Computer SID would be duplicated.
