Public Folders Not Available After 2003 to 2010 Migration

Hello All,

I have done a swing transition from Exchange 2003 to 2010. All the mailboxes moved over just fine and are working. I also did a move replica on the public folders which seem to have moved at the least according to Exchange System Manager in 2003 they are now located on the 2010 server.  In the 2010 managment console they appear just fine and suggest they are located on the 2010 public folder database.

The problem is that they do not appear in anyones Outlook. They do appear in OWA but generate an error to talk the adminiistrator when you try to access them.

Anyone have any suggestions?  Any help is appreciated.

Did you ever begin replicating the public folder?  You have to go in manually and select which folders to replicate form 2003 to 2010.  Is the old server still up?

I have moved replica as per this:


Old server is still online.
Before that step, you had to ensure that they were replicating.  In other words, id you right click on each public folder and select the new server database as a replication partner.

Did not do that.
A new Public Folder database will also be automatically created on the new Mailbox Server. The hierarchy, which is the structure of all Public Folders will be automatically replicated between all Public Folder Databases in the entire organization. The content replication of the Public Folders will have to be configured manually though.

To replicate the Offline Address Book and Free/Busy folders from Exchange Server 2003 to Exchange Server 2010 open the Exchange System Manager on the Exchange Server 2003 server and navigate to the System Folders in the ‘Folders’ folder in the First Administrative Group Navigate to the first Offline Address Book folder, right click it and select “All Tasks…”. The next is to select “Manage Settings”.

If you want to toggle between the System Folders and the normal Public Folders, navigate to the Public Folders, right click the Public Folders and select “View System Folders” or “View Public Folders”.

The “Manage Public Folder Settings wizard” will appear. Click Next on the Welcome page and select the “Modify lists of replica servers”. Follow the wizard and add the Exchange Server 2010 Mailbox Server role as a new replica. When finished, the folder and all its subfolders will be replicated to the Exchange Server 2010 Public Folder database. Repeat this step for the second Offline Address Book folder and the Schedule+ Free Busy folder.

Note: When the “Manage Settings” option is not available you can select “Properties” and select the replication tab to add the Exchange Server 2010 Public Folder Database.

Note: replication of public folders can take quite some time.

The (default) Public Folder that are located on the Exchange Server 2010 Mailbox Server should be replicated to the Exchange Server 2003 Mailbox Server. To accomplish this logon to the Exchange Server 2010 Mailbox Server, open the Exchange Management Console and navigate to the Tools node. Under the Tools node open the Public Folder Management Console.

Right click the Offline Address Book in the results pane, select Properties and click the Replication tab.

Add the Exchange Server 2003 Mailbox Server to the replica list, the contents will now be replicated to the Exchange Server 2003 Mailbox Server. Be aware that Public Folder replication is a low priority mechanism, so it takes some time before both Public Folder databases are in sync.

Repeat these steps for the Schedule+ Free/Busy folder.

the above was from

this should help you get replicated.

This is a good guide. I am giving you points for posting it and closing this question. My issue is more complicated and Microsoft support is involved now.
