Global address list pb in Exchange 2010

Hello all,

I have an address list pb in my organization.

I have this warning i my journal server :

"OABGen could not generate full details for some entries in the offline address list for address list '\Liste d'adresses globale'.  To see which entries are affected, set event logging for the offline address list generator to at least medium."

And when i try to access to the global address list with OWA, i can't :

I think the pb comes from the deleting of the "All rooms" address list. Have you got any others ideas ? Is it possible to restore the specific address list?

I tried this explenation without succes :
http://blogs.msdn.com/dgoldman/archive/2007/12/05/deleting-the-all-rooms-address-list-stops-it-from-showing-up-in-owa.aspx

I don't have DN {All Rooms DEL: in msExchResourceAddressLists attribute.
But when i lauch the command to list Organization config i have (Toutes les salles = All rooms) :

"[PS] C:\Windows\system32>Get-OrganizationConfig

Have you got any solution?
Thanks,
