Changed distribution list not able to receive email

I have an Exchange Universal distribution group that was deleted and recreated.  The Exchange address book seems to be holding on to the old group.  The groups was recreated exactly the same as it was but when internal users email to that group messages are rejected. If the email address is typed in manually the message goes thru successfully.

That is probably the outlook name cache.  
For a quick test, have them pick the group name out of the address book and *not* type it in.  Chances are it will work.

Assuming it does, there are some things that can be done, and some things to watch out for.
If they have Outlook 2003/2007 (or older), you can delete any *.nk2 files in their profiles (or there is software to edit these files).  Then they will begin building new ones automatically.

With newer versions, I'm not sure how you would reset that from an administrative point of view, but the users can manually eliminate those entries by typing in the name, and when it appears on the screen, use the down arrow until it is highlighted, and hit the delete key.  Then the next time they type it in, it will be cached.

Now -- one important fact.. they cannot reply to any of the old emails from that group.

Hello,

Read my article here - http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/A_9650-NDRs-and-the-legacyExchangeDN.html

It will explain how you can add an X500 address to the distribution group, which matches the legacyExchanDN of the old group. This will allow mail to reach the new group when users reply to old emails or their autocomplete still have the old group.
