Message to distribution group stops at thecategorizer!

[Lisa]

Hello all,

I've Exchange 2003 sp2 on Windows 2003 sp1, recently when I send mail to
distribution group the message tracking shows that the message ends up with
the categorizer and that's it !!!

I just had this problem as well. I did a Google search on it (Distribution
Grop stuck in categorizer) and found a few articles on it both in web and
groups. Do you have multiple domains? My setup has a root domain and a
resource domain where all our users are. I just saw this issue this week. a
lot of the articles talked about the server not being able to talk to a
Global Catalog to expand the group. My DG was a global group. I changed it to
Universal and it went right through. Although 99% og my Distribution Groups
are Global and not local, changing it to Universal worked. Since I do not
have users in multiple domains I amnto worried about replication traffic if
changes to tha group are made. However, my priority was getting the group to
work since it contained 20 "high profile" users. Try chabgin it to Universal
and see if it works.

Change it to a universal group. The membership of all universal groups is
stored in the GC partition of all GCs. The membership of a domain group is
only contained on DCs in that domain. You must specify an expansion server,
exchange must be able to contact the expansion server, and the request must
succeed, otherwise a null (empty) result set is returned and the message
dies at the categorizer because it has been delivered to null set (the bit
bucket).

You could muck around with troublshooting connectivity and calls to DCs, but
the easiest solution and the best practice is to make distribution groups
universal groups and avoid the whole problem.
