Cannot access Public Folders after 'Move All Replicas' from Exchange 2003 to Exchange 2007

Hi Guys,

We've installed a new server with Exchange 2007 on and have migrated all the mail across from the exisiting Exchange 2003 but along this we had right clicked on the Public Folders on the Exchange 2003 box and let it run for 4 days now. Now no-one can access any Public Folders and they don't even show up when you choose folder list and Public Folders in Outlook, the odd thing is that if anyone has a Public Folder as a favourite then they can access it fine.
The Public folders on the 2003 box are showing as 'In Sync' and have 2 copies, if i look at the Public Folders folder on the 2003 box it shows empty but the Public Folder replicas all show the folders there but on the 2007 box there's nothing showing at all.
Any ideas ?

First make sure you have a backup of the public folders (stop exchange and copy the database files). If the public folders are not to big I would recreate them on the 2007.

Not quite sure I caught what you did with your public folders.  Can you let me know if you have the latest service packs on both Exchange servers?

You said you migrated your mail, did you actually do the migration for the public folders?  You have to do this by setting the Exch07 box as a replica on each public folder.  Then after confirming the data was there you remove the replica for 03.

You said that on the Exch03 server they show "In Sync" and have 2 copies, but you can't see the folder in 2003?  That doesn't make sense.  You can't manage (see) public folders on Exch07 unless you are running SP1 if I remember right.  So you may not be able to see them if you haven't updated.

Hope that helps.

The mail was migrated by going onto the Exchange 2007 and moving the mailboxes and this all went fine. We then went onto the 2003 box, right click the Public Folder database and selected 'Move Replicas' which then brought up another window where we chose the new server and then it accepted this and we waited for a couple of days. If we then go into ESM on the 2003 box and check the new 2007 server from there it doesn't show any Public Folder Instances (i.e the one's we have created on the 2003 server) but on the 2003 box they all show there.
I've manually gone into each public folder and the 2007 server is showing in the replication tab.
The 2007 server had been updated but the Exchange isn't showing any SP1 so i'll download and install that first and post back shortly.

Sorry, I should have posted this.  You can tell only by the build number.  The latest SP for 2007 is SP3 build 8.3.0083.006

Here is the link for future reference:

I'm not sure if this is relevant but if i go into the Exchange 2007 and go to Address Lists - Public Folders - Edit - Preview i can see all the Public Folders there.
If i then go through the wizard bit that's there it shows "The recipient domain.local/Microsoft Exchange System Objects/OAB Version 3a is invalid and could not be updated.

This repeats for other Public Folders.

I found out after a lot of research that the existing Exchange 2003 send the Folder Replicas through SMTP and it had a smart host on it and so although the infrastructure parts of Public Folders showed as moved the actual folders went out through the smart host to the internet (i.e to nowhere). I changed the smarthost to point to the new Exchange 2007 box and it has worked fine.
