Free/Busy Availability between two Sites

Hello,

We have multiple sites across UK running AD and Exchange 2010 in the One Organization with coexistence of couple of Exchange 2003 hosting Free/Busy in HQ.

Each site has cluster of Mailbox servers, CAS and HUB servers.

Since the Free/Busy was located only at HQ I recently created a Public Folder Database at one of the branch offices and added it in the replica list of Free/Busy.  Since this the users in branche office are able to access Free/Busy without any lag where as previous it use to take few seconds before Free/Busy was retrieved.

My question is what happens if the link break between the two sites? Will Free/Busy still continue to work for both sites? By the way the users in branch office do not require to see Free/Busy of users in HQ.  Users in branch office only need to be able to see Free/Busy of users in that branch because each branch run there own operation and have separate email domain also the MX feed plus segmented GAL.

All users use Outlook 2007, 2010 no 2003

Please advise whether Free/Busy will continue to work at both sites in the event of loss of link??

If the mailbox database on each site has an associated public folder database then F/B won’t be affected if the connection between the sites breaks.
To be sure, check the following on each PF database:
-in order to post F/B information Outlook need a system public folder matching the legacyExchangeDn of the user and a folder similar to this:
EX:/o=OrgName/ou=The NAme of Your Admin Group
-check my article for additional info >

We are talking about Ex2003 here because OL2007 and Ol2010 on ex2010 will use availability service for F/B and not public folders.

So basically you are saying that since we do not have any Outlook 2003 or below at the branch office there was no real need to add the new Public Folder DB for the branch office to the replica list for Schedule + Free Busy under System Folders? which currently reside on old Exchange 2003 server...

I dont follow ... if your branch office is on Ex2010 then users (not on Outlook 2003) on that site wont need public folders for  F/B distribution.
However the same users wont see F/B on users on a site with ex2003

Exchange 2003 > need PF for F/B > true
Exchange 2010 and no OL2003 >need PF for F/B > false
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

So if there were all Outlook 2007 and higher clients  at both sites then will the Free Busy Public Folder would be redundant and can be deleted?? And if the link does go down the FreeBusy info will be limited to the users in each site?
