Yes, but in the case of Outlook 2003, they use the OAB first. http://www.petri.co.il/gal_problems_and_oab_automatic_updates_in_outlook _2003.htm ________________________________ From: Michael B.

OAB (any PF change) requires a recreation of the profile. Let's see, from my book: The process of accessing information from a public folder, because of the referral mechanism, is fairly complicated; but very versatile. It is designed to give a user multiple efficient paths to access replicas of any given public folder. If a particular replica should not be available, then another (hopefully identical) replica is chosen from which the user will retrieve information. The process goes like this: * A user requests data from a public folder * The Information Store (IS) returns a list of all the replica's that hold that data (for example, see Figure 6-1) * The IS requests the Routing Engine (RE) to assign a cost to each replica * Replicas that have infinite cost are discarded by the IS * Replicas whose connectors are known to be down are discarded by the IS * The IS sorts the remaining replicas by cost within the current Routing Group, and then by cost outside the current Routing Group * If the user is on the same server, then the IS directs the request to that server * If there is an available replica in the current Routing Group, then the IS directs the request to that server (if there are multiple choices at the same lowest cost, then the client picks a server at random from the available choices) * If the available replicas are in a different Routing Group, then the IS directs the request to a server in the Routing Group with the lowest cost (if there are multiple choices at the same cost, then the client picks a server at random from the available choices) * If there are no replicas available, the user is denied access From the client messaging application perspective, it requests information about where to access a public folder, and the application is returned a list of direct access locations, of which it can choose any. All the complexity is hidden within the Information Store and Outlook. A user will, by default, reuse the same selected server each time a particular public folder is accessed. .... For more detailed information on public folder referrals, see Microsoft KB 273479. ________________________________ From: Harding, Devon [mailto:dharding@xxxxxxxxxxxxxxxx] Sent: Wednesday, June 08, 2005 4:40 PM To: [ExchangeList] Subject: [exchangelist] RE: OAB Replication http://www.MSExchange.org/ So if a user in another AG is running Outlook 2003 w/cached mode enabled, they'll use their local Exchange server for GAL/OAB if I choose to replicate to all? ________________________________ From: Michael B.

They aren't by default. In Exchange 2000 and 2003, they are public folders. So if you replicate them and you recreate a user's profile, they will use the "closest" PF server after that. ________________________________ From: Harding, Devon [mailto:dharding@xxxxxxxxxxxxxxxx] Sent: Wednesday, June 08, 2005 4:09 PM To: [ExchangeList] Subject: [exchangelist] OAB Replication http://www.MSExchange.org/ We have 20 Exchange servers in 12 Admin Groups.
