Exchange 2007: Distibution Lists, undeliverable

Our company has one central Exchange 2007 server and two Exchange 2003 servers.  We have a problem when a new Distro list is created. I have tried the following things:

For the 1st list (FRIT PSG) list, I created a Universal distro list with the ADUC on the Exchange 2007 server. After, the list did show in the Global Address Book, but no members were visible nor was the list editable.

The next day, I used Exchange 2007 Management Console and imported the "Existing Group" as a distribution group. This process was successful and the members of the list did then show in the GAL. However, the users sending to the list were still getting undeliverable notices.


The 2nd list (FRUK PSG) I created the distro list exclusively with the 2007 EMC. Again the creation of the list was successful. But, when a mail is sent to the list from an Outlook client it is undeliverable.


The Outlook Client:
We have a mix of Outlook 2003 and Outlook 2007 clients. As 70% of our users are mobile, we use Cached Mode for all Outlook Clients.

Web Mail:
If you send a mail to the either Distro List from Outlook Web Access then the message is delivered without error.


The Undeliverable Message:

Delivery has failed to these recipients or distribution lists:
 
FRUK PSG

Since, you are in cached-mode, try downloading the Address Book so that you have the address in the GAL.

Go to Tools->Download Address Book.
Or take off Cached mode, then you will be looking at the current address book, just like OWA.

We have tried the download of the address book. But the problems remains.

Yesterday for example we created a new user. Today it does not show in the OAB. Again, if we look in OWA the address is there.

So it seems to us that the real problem is with the update of the OAB as it seems to affect both new users and new Distro lists on the mobile computer.

Any ideas how to sort this out is appreciated.

It seems we found the source of the problem. First we must create the Disto List in ADUC 2003. Then we have to import the list into the Exchange 2007 EMC. After it is imported we did have to uncheck the "Automaticly update email address based on email address policy". After doing this the list work properly.

We would be interested in why this is the case. If anyone can shead some light on that, it would be appreciated.

The solution to this problem was a missing string for the object in Active Directory. Using the String Attribute Editor, we changed the attribute: leagacyExchangeDN to value: /o=FANUC Robotics Europe SA/ou=FREU/cn=Recipients/cn=ICT

This corrected all delivery problems.
