Hello I am part way through migrating from Exch 2007 to 2010. All my mailboxes are over and the new server is working as I want it to. The problem has come when trying to un-install the 2007 server. I get the following error: Summary: 3 item(s). 2 succeeded, 1 failed. Elapsed time: 00:00:20 Mailbox Role Prerequisites Failed Error: Uninstall cannot continue. Database 'Public Folder Database': The public folder database "JUPITER\Second Storage Group\Public Folder Database" contains folder replicas. Before deleting the public folder database, remove the folders or move the replicas to another public folder database. For detailed instructions about how to remove a public folder database, see http://go.microsoft.com/fwlink/?linkid=81409.

Below is what I get when trying to follow the standard process of moving them. [PS] C:\Windows\system32>MoveAllReplicas -Server Old -newserver new Set-PublicFolder : The parameter "Replicas" cannot be $null or an empty array. At C:\Program Files\Microsoft\Exchange Server\Scripts\ReplaceReplicaOnPFRecursi ve.ps1:147 char:24 + $_ | set-publicfolder <<<< -server $_.OriginatingServer; + CategoryInfo : InvalidOperation: (\NON_IPM_SUBTRE...ne Address Book:PublicFolderId) [Set-PublicFolder], InvalidOperationException + FullyQualifiedErrorId : 7492CDDB,Microsoft.Exchange.Management.MapiTasks .SetPublicFolder I'm not the most experienced exchange admin so it could be something simple ive over looked. Thanks in advance.

Is SMTP working correctly between the servers? This is the most obvious question but most of the time its the answer.MVP Exchange Server

As far as I'm aware it is. All the mailboxes moved over fine and they are both on the same LAN and communicating for other things like AD etc...

Can you confirm with telnet to port 25? We need to confirm this first.MVP Exchange Server

Yeah SMTP is working between servers. I've messed about with the system public folders (there are no others) and now when I run 'MoveAllReplicas -Server Old -newserver new' the command doesnt throw up any errors but I still get the same message when trying to un-install. I have waited a few hours between trying as well not that it should talk long to replicate when there is next to no data in the folders.

If you can confirm the PF's have been replicated properly and rehomed to the Exchange 2010 Server then you can just manually remove the Ex2007 PF store, I have had to do this a few times so I could just get the Ex2007 uninstall to proceed. In ADSIEdit, go to Configuration, Configuration, Services, Microsoft Exchange, FirstOrganization, Administrative Groups, Exchange Administrative Group, Servers, Servername, Information Store, First Storage Group. Then on the right hand pane, highlight the Public Folder Store and Delete it.MVP Exchange Server

It looks like that might have worked! I wasnt viewing the adsiedit tool correctly so its taken me until now to find the configuration section. Thanks for the clear instructions. I'll post back if it errors, its a slow server so will take a while to uninstalled Id imagine.

Hi, ADSI Edit is a useful tool can help us troubleshoot the Exchange issue. AllenAllen Song
