Hi, i've detected that the active node in exhange 2k7 is not stable, then i proceed to change the cluster to the pasive node that it more stable tha the other one, now the only problem that i have is that the user with cache mode in outlook doesn't update the address book, because i understand that the only allow for this is the active node. Now my question is i don't like use the active node (all the Storage group replication between node is ok), i would to continue using the pasive node even update the OAB... what can i do. Regards

Are you seeing the errors referenced in that article? If so, then I would make those registry changes.
