Exchange fails to deliver to all Distribution Group members
Posted on 2010-08-24
We seem to be having an annoying issue with our Exchange server, whereby not all members of a particular Distribution group are actually receiving emails sent to the group. It seems to vary on each occasion as to who actually does and doesn’t receive the group emails, but out of 45 members no more than 15 ever seem to get them.
We’ve tried deleting and recreating the Distribution Group in question, which seems to have had no effect whatsoever.
I’ve also done a full defrag of the Exchange database, and while I wasn’t able to do a repair (as Exchange was in a ‘clean shutdown state’), I did run isinteg which found and successfully corrected a handful of errors.
Everything I seem to find in relation to people having these sorts of issues always comes back saying its Exchange database corruption, solve it with eseutil and isinteg. But if I’m getting clean isinteg results shouldn’t that mean my Exchange database is fine? Is it possible that it’s actually an Active Directory issue?
