In the default email policy, I deleted the X.400 address. Now I'm discovering that X.400 is required for our legacy 2003 Exchange server or the Information Store service will not start (http://support.microsoft.com/kb/329599/en-us
) and I need to start it up one last time to replicate before removing it from our setup.
I can't find any documentation on how the syntax is supposed to be built for an X.400 proxy address within Active Directory. Any ideas?
