Exchange 2003 - 2010 Transition Public Folders disaster

Hi,

I am in the middle of a co-existence Exchange Server 2003 to 2010 transition. It's been a bit of a slog, but I've got to where I thought was a good place. I haven't migrated any users across from 2003 yet as I still need to migrate users from an Exchange 2010 server in another forest.

I added the Exchange 2010 server as a replica for all the Public Folders using the "addreplica" script. That all went OK. After a few days, I ran the 'Move All Replicas' command from Exchange 2003 ESM. That took a while, (like a day and a half), but after checking the "Public Folder Instances", everything had been moved across.

I wasn't going to do anything else with Public Folders until the very last thing before I migrated my 2003 mailboxes across and decommissioned the 2003 server.

However, I had a call from one of our Entourage 2004 users to say that she couldn't see anything in her Public Folder. Right, OK. Exchange 2010 doesn't use WebDAV anymore so that's why Entourage won't work. I thought I could just add the Exchange 2003 server as a replica for all the Public Folders, everything would flow back, and that would be that.

It all started OK. All the folders have replicated across, and I can see them in the Public Folder Instances on the 2003 server, but very little of the Public Folder contents have come across. Nothing I've tried is working.

I've had a look at the Event logs on both servers. On the 2010 server, I was getting an error "The store driver couldn't deliver the public folder replication message "Backfill Request (EX2003-IS@domain.com.au)" because the following error occurred: Property: [0x3ff00102] , PropertyErrorCode: UnknownError, PropertyErrorDescription: 0x80040107".

I read that you should install Rollup 2 for SP3 on the Exchange 2010 server, but I already have that installed. That error lasted for about 5 minutes, and then stopped. No other errors for a couple of hours.

I'm just not sure if it's being INCREDIBLY slow to replicate back, or that nothing is happening at all.

Any guidance is appreciated.

Thanks.

Steve

Couple of things to add;

1) the routing connector between EX2010 and EX2003 is working.
2) EX2003 and EX2010 are set on the Replication tab for every Public Folder, both on the EX2003 server and EX2010 server.

Do all the System Public Folders need to be replicated back too?

Hi,

I'd previously seen that link. All the folders have replication servers set, (and all sub-folders too).

I fixed it. I realized Rollup 1, not Rollup 2 was installed. Once that was installed, I made sure the admin account I was using had access to the public folders. Syncing then started to happen for all the folders.
