Exchange 2010 Distribution Group in Outlook 2003


I've created a new distribution group in AD and linked it to the exchange distribution groups
In Outlook 2007 i see the new group and i can also write emails and expand the group
but in outlook 2003 i see only the old group (there was an old group linked to exchange before with the same name, i changed the name and disabled the group. The group still exists in AD as an security group. I need to split up the group one for security and one for distribution) the new has the same alias like the old but a other name...

We are running Server 2008 R2 Exchange 2010 and clients are xp and office 2003
only some pcs got 2007 office and here is no problem with the new and the old groups

ive tried to download the adressbook under 2003 but it still cant find the new group and for some reasons the old group is still in the adressbook, but only in outlook 2003 !
When i choose the old group in 2003 and try to expand the distribution group he cant find it

so what can i do?
thanks for the help

It looks like your outlook 2003 is not up to date with new informations.

Do you have the possibility to turn off the Cache mode (no use of OAB) and see if group appears in outlook 2003 ? If you can not modify the current profile (mobile user, big mailbox to synchronize) then you can create a test profile.

ok thanks for the reply

if i uncheck the cache mode then i see my new group with all members in 2003
good idea but when i check the cache mode ill come back to the old adressbook with the old distribution group... any ideas to refresh recreate the list?
i think it would help to set up the mail prifle compleatly new but some users have 10gb of mail boxes so this is not the best way  
on server side:
get-addresslist |update-addresslist

Wait a few seconds.

On user profile on Windows client close all outlook windows, check outlook process is not running, go to %userprofile%\local settings\applications data\microsoft\outlook and delete OAB files. This is safe but you still can keep them in a "old" directory

Start outlook, go get a coffee, the sync will start ~4 minutes after outlok is started.
Check that new OAB files are created, close/open outlook again, and test if group is here
edit : second line

get-globaladdresslist |update-globaladdresslist
